REDUCED POLLUTION POWER GENERATION SYSTEM AND GAS GENERATOR THEREFORE

Abstract: Pollution-free or low pollution, efficient, large scale electrical power generation systems, using thermal energy from combustion of hydrocarbon fuel are described herein. The pollutant-free hydrocarbon fuel is combusted in a gas generator with pure oxygen or substantially pure oxygen that is free of nitrogen. Water is also injected into the gas generator. The gas generator discharges high enthalpy steam and carbon dioxide which can then be utilized in a variety of applications, including driving turbines for power generation. The steam can be recycled into the gas generator or discharged for various uses. The carbon dioxide can be collected for industrial use or discharged.

Description: REDUCED POLLUTION POWER GENERATION SYSTEM AND GAS GENERATOR THEREFORE Technical Field This invention relates to systems for the efficient generation of environmentally clean energy by combustion of hydrocarbon fuel, focused on the commercial generation of electrical power. This invention also relates to low pollution gas generators for industrial applications where the working fluid used requires variable temperatures and pressures such as in food processing, oil well high energy gas injection, medical and greenhouse facility constant temperature control, and other applications. Background Art The current art in generating a major portion of commercial levels of electrical power, in the United States and world-wide, depends upon thermal generating plants burning hydrocarbon fuels (mainly coal and low grade fuel oils) with air, which contains 23.1% oxygen and 76.9% nitrogen by weight, to generate high enthalpy steam which, in turn, is used to drive turbo-electric generators. The technology of designing, constructing and operating extremely high energy generators for jet engines, rocket engines, and gas turbine auxiliary power systems, has been significantly advanced in recent years. Generation and controlled use of such extremely high energy levels is a specialized practice and is readily adaptable to commercial industry. The current state-of-the-art in power generation results in the production of atmospheric pollutants, mainly high levels of nitrogen oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO) and particulate matter. Such emissions are at, and in a great many cases above, critical allowed threshold levels and must be reduced to preserve clean air. Current United States regulatory requirements prescribe the amounts of the above listed atmospheric emissions permitted in particular locations by a given power generating plant. Allowable emission thresholds are decreasing over time putting more and more pressure on industry to reduce emissions. Drastic economic penalties are being established, either in the form of fines (called purchased credits) related to the amounts by which emissions exceed allowable limits, or plants can be ordered to cease emitting operations. In addition to the undesired effects of the build-up of atmospheric pollutants on the quality of the environment, current art extracts further societal prices in terms of the added costs of pollution control and monitoring equipment, and the purchasing of credits which are passed on to the consumers. There have been many efforts to solve the emissions problem by exploiting non-combustible energy sources, such as windmills, fuel cells, solar cells, closed cycle solar reflector/boilers, use of tidal motion and others None of these sources can approach the required output levels in a cost-effective manner, with operating efficiency required for large-scale, sustained commercial applications currently supplied by the conventional thermal power generating plants. Nuclear plants can produce at the required levels of outputs, but they have encountered regulatory requirements leading to high costs, and there is a strong societal opposition to increasing use of nuclear power. Hence nuclear power use in the United States is severely restπcted. Disclosure of Invention This invention is a unique, well developed technology for a high temperature, high pressure combustion device, designed to produce and control an efficient, high energy fluid stream, without generating unacceptable pollution, and which is usable in a vanety of embodiments described in this application The thermo- mechanical design and physical conformation are specific features the purposes of which are efficient operation, pollution avoidance, long life and minimum maintenance These results are accomplished through unique integration of a number of advanced combustion technologies using selected reactants in a water cooled device generating a high puπty steam and carbon dioxide working gas. Elements of pnor specialized technologies are adapted and combined in the design of a thermal power generating plant which can operate cleanly using any of several relatively inexpensive and widely available reactants including liquid oxygen, propane, methane, natural gas, or light alcohols such as ethanol and methanol. These reactants are or can be placed in mass commercial production and distribution, being already in extensive use in other fields such as home heating, cooking, industrial heating, metal cutting and welding, aerospace propulsion applications and others. Further, these reactants can be burned at high temperatures, in high pressure combustors which, while not currently widely used in the power industry, are a practiced art in the aerospace industries, but without emphasis on environmentally clean operation in those applications. In this invention, the combustor is a high energy, continuous flow device. The liquid reactants (including a hydrocarbon fuel, oxygen and water diluent) are injected into a combustion chamber, via an efficient, high performance, specialized injection device, under high pressure, generating high temperature gas. In combusting any of the fuels with liquid oxygen under controlled conditions (i.e., combustor pressure, temperature and fuel/ oxidizer mixture ratio), the products of combustion are high pressure, high temperature steam and gaseous carbon dioxide, with virtually no NOx, SOx, CO or particulates generated, depending upon the puπty of the fuels and oxidizers used, and the controls of the combustion process. The carbon dioxide product can be recovered during the steam condensing process for commercial use. Current costs of the fuel elements generated in bulk by existing, large scale production facilities, are relatively cost competitive with coal and oil The release in an appropπately scaled reactor produces power at a cost that is competitive with current thermal plants, yet this invention will not yield the massive amounts of polluting gases, thus avoiding the additional penalty costs of pollution control equipment and purchased credits for excess emissions. A specially configured version of this invention takes the form of a source of a high quality fluid, which can either improve a number of existing commercial applications (e.g. food processing, materials sterilization, oil well injection, etc.), or enable new applications such as intermediately scaled mobile plants for temporary, on-site power support, or non-polluting, steam powered drive systems for large locomotion systems such as trains or ships. Brief Description of Drawings Figure 1 is a schematic showing an embodiment of the invention, its elements and connectivity that constitute an efficient, pollution-free power generation system. Liquid reactants are shown being introduced to the system from sources that may be either on-site or adjacent production facilities, or from storage facilities. This embodiment features system enhancing elements which maximize energy utilization and minimize component size through turbine drive gas regeneration and inter- turbine drive gas reheating. Figure 2 is a schematic showing an embodiment of the system from which the inter-turbine reheaters were removed, which simplifies the system of Figure 1, reduces cost, and slightly increases performance, but at the expense of increased component sizes and weights. Figure 3 is a schematic showing an embodiment of the system from which both the reheaters and regenerators were removed, which simplifies the system of Figure 2, further reduces cost and decreases system performance, but at the expense of further increased component sizes and weights. Figure 4 is a schematic showing an adaptation of embodiment 3, from which the recirculating water circuit and customer supplied heat rejection system were eliminated, with water supplied from a source (e.g., lake, river, or purified sea water), thus eliminating the complexity and cost of the closed loop water recovery and heat rejection subsystems. Figure 5 is an illustration of an embodiment of the basic concept which uses those elements of the system required to generate the drive gas only. The generation of the high pressure, high temperature, high purity steam and carbon dioxide mixture that this system is capable of delivering has multiple industrial applications (e.g's., oil well injection, material sterilization, or heating of large structures or building complexes, and others). Figure 6 is an illustration of an embodiment that is a modification of Figure 5, wherein the gas generator output is used to power a turbogenerator set, with components sized to mount on a mobile platform for applications such as remote site construction or exploration, auxiliary or peaking power supply, service power, or large locomotive drive applications, such as for trains or ships. Figure 7 is a cut-away diagram showing the elements of the main reactor (or gas generator). This illustration shows the functional elements of the device, including the reactants' inlets and manifolds, the injector, the transpiration cooled combustion chamber, and the internal mixing chamber and outlet. Figure 8 is a cut-away of a typical mter-turbine reheater. The device is a specialized version of the main reactor. The size of an individual reheater is dependent on the physical state of the out-flow received from the preceding turbine unit. Best Modes for Carrying Out the Invention Figure 1 illustrates a non-polluting, efficient electrical energy generating power plant 1000, compπsing a reactant induction subsystem 100, a gas generation subsystem 200, a reheated turbine drive subsystem 300, an electrical energy generation subsystem 400, an exhaust management subsystem 500, and a regenerated water management subsystem 600. The reactant service subsystem 100 feeds and controls the flow of the fuel and oxidizer reactants that power this system. This includes a liquid oxygen (LOX) feed line 1, feeding the LOX pump 2, which is powered by dπve unit 6. The LOX pump 2 delivers high pressure LOX to the system gas generator subsystem 200, via the discharge line 3. High pressure gaseous or liquid fuel is delivered to the gas generator subsystem 200 through feed line 4. The drive gas generator subsystem 200 includes a gas generator 7, which efficiently combusts the injected reactants under controlled conditions, producing a high pressure, high temperature gaseous mixture of steam and carbon dioxide which is delivered as a turbine drive gas. The dπve gas is delivered to the high pressure turbine drive 13, in subsystem 300, via discharge line 10 Thermal control of the combustion process can be accomplished by controlling cooling water flow rate to the gas mixing chamber and to the chamber structure via water feed lines 64 and 66, supplied by water service feed line 65, from the water management subsystem 600. The turbine dπve subsystem 300, converts the gas generator subsystem 200 output energy into mechanical energy to dπve the electπcal generator subsystem 400. The turbine subsystem 300, consists of three power turbines, pressure staged for optimum efficiency, and two mter- turbme reheater units to maximize the energy in the dnve gas. The turbine dπve subsystem 300 consists of high pressure power turbine 13, high pressure power turbine exhaust line 11, and high pressure power tap-off line 45 This assembly is followed by an mter-turbine reheater in which the exhaust temperature is brought back to that at the gas generator outlet by combusting the proper amount of the reactants in the reheater chamber and mixing the output with the main flow stream, thus adding energy and maintaining constant inlet temperature going into the next turbine. This takes place in the first inter-turbine reheater 62, w hich consists of the reheater 62, and reheater LOX feed line 56, reheater fuel feed line 57, reheater water feed line 68, high pressure turbine steam exhaust from line 1 1, and reheater discharge line 59. This section is followed by a medium pressure range power turbine 14, medium pressure power turbine discharge line 12, medium power turbine tap-off line 15, followed by the second reheater unit consisting of inter-turbine reheater 63, reheater LOX feed line 58, reheater fuel feed line 60, reheater water feed line 69, medium pressure turbine steam exhaust from line 12, and reheater discharge line 61. The turbine power section is terminated by a low pressure power turbine 17, and discharge line 25, which sends the gas flow to an exhaust recovery condenser 41, in the exhaust recovery subsystem 500. The energy generation subsystem 400 is the electrical energy conversion facility 18, consisting of electncal generator(s), and power conditioning, which develop the end product of this plant, electncal energy. The exhaust management subsystem 500 is a gas handling subsystem with two purposes: (I) to make the most efficient use of the exhaust products, and (n) to veπfy that pollution controls are effective. This subsystem consists of a carbon dioxide recovery branch and a water recovery branch, both serviced by the heat rejection facility 30. The carbon dioxide recovery assembly receives near ambient temperature, gaseous carbon dioxide (CO2) from the condenser 41, via discharge line 19, and from the water management subsystem 600, via discharge line 47, into compressor 20, which is powered by dπve unit 21. After one stage of compression, the gas is delivered to a water cooler 26, via discharge line 23, and, after cooling by passage through the heat exchanger section of the cooler vessel 26, the fluid is returned to compressor 20, via return line 24, and further compressed before discharge to facility return line 5, for recovery processing. Cooling water is supplied to cooler 26, from the heat rejection facility 30, by cooling water pump 34, powered by dπve unit 36. Cooling water is drawn through inlet line 33, and delivered through pump discharge line 31, and cooler inlet line 28. After passing through the heat exchanger element in cooler 26, the cooling water is returned to the heat rejection facility 30, via discharge line 29. Carbon dioxide is also recovered from preheater 93 via discharge line 94. The water recovery branch consists of the condenser vessel 41, cooling water inlet line 27, which sends cooling water through the condenser 41 heat exchanger section to cool down and condense the exhausted steam back to water. The cooling water is then returned to the heat rejection facility 30, via cooling water outlet line 22, and the condensed water is returned to the water management subsystem 600, via discharge line 37. The water management subsystem 600 maintains the proper water balance in the operating system 1000. It does this by maintaining the proper cooling water injected at the gas generator inlet. The major product of combustion, using the reactants intended for this system, is water, therefore following start-up there is more than enough water available to operate the system However, to insure adequate water availability during start-up, shut-down, and other transient operations, the heat rejection facility will serve as a reservoir as well as a receiver for any excess water generated. The main elements in the embodiment of the water management subsystem 600 are pressure staged pumps 16a, 16b, and 16c, powered commonK b\ dπve unit 9, condensate pump 38, powered by dπve unit 39, and two (2) performance enhancing regenerator units 46 and 93. The water recovered in the exhaust management subsystem 500 is returned to the water supply from condenser 41, discharge line 37, to condensate water pump 38, which is powered by drive unit 39. Condensate water pump 38 delivers the water to the feed water pumping system via discharge line 40. Excess water is diverted to the heat rejection facility 30, via return line 35, or any required start-up or make-up water is drawn from the heat rejection facility 30, via inlet line 95 and delivered to the inlet of pump 16a. The mam water flow is delivered to the feed water pumps 16a, 16b, and 16c by the condensate pump 38, via feed line 43, which is joined by a recirculated flow from the medium pressure turbine tap-off line 15. This tap-off flow serves as the heat source in the heat exchange element of a regenerator device, regenerator 46, to conserve heat energy. The tap-off flow is collected in a sump in regenerator 46, and discharges to the low pressure feed water pump 16a, via discharge line 48, of regenerator 46 and pump 16a inlet line 43. An initial stage of feed water pressuπzation is accomplished in low pressure feed water pump 16a. The outflow of pump 16a is earned to regenerator 46, via discharge line 49, picks up heat energy in the heat exchanger element in regenerator 46, and then is passed to the medium pressure feed water pump 16b, via heat exchanger outlet line 50 and through inlet line 51. The water flow is joined by a recirculated flow that oπginates from the high pressure power turbine tap-off line 45. This tap-off flow serves as the heat source in the heat exchange element of the regenerator 93, to further conserve heat energy. The tap-off flow is collected in a sump in regenerator 93, and discharges to the medium pressure feed water pump 16b, via sump discharge line 92, of regenerator 93, and through medium pressure pump inlet line 51. The feed water flow stream is passed to the high pressure pump 16c, via medium pressure feed water pump 16b's discharge line 90. The high pressure pump 16c raises the mam stream water pressure to the design level then discharges it via discharge line 91, to the heat exchanger section of regenerator 93, where it picks up more heat energy before finally being passed to the gas generator subsystem 200, and the reheaters 62 and 63, in the power turbine subsystem 300, via discharge line 8, and reheater cooling water line 65. The feed water pumps 16a, 16b and 16c are powered by the common dπve unit 9.

The reactant service subsystem 100 feeds and controls the flow of the fuel and oxidizer reactants that power this system. This includes a liquid oxygen (LOX) feed line 1, feeding the LOX pump 2, which is powered by dπve unit 6. The LOX pump 2 delivers high pressure LOX to the system gas generator subsystem 200, via the discharge line 3 High pressure gaseous or liquid fuel is delivered to the gas generator subsystem 200 through feed line 4 The drive gas generator subsystem 200 includes a gas generator 7, which efficiently combusts the injected reactants under controlled conditions, producing a high pressure, high temperature gaseous mixture of steam and carbon dioxide which is delivered as a turbine drive gas. The dπve gas is delivered to the turbine drive subsystem 300, via discharge line 10 Thermal control of the combustion process can be accomplished by controlling cooling water flow rate to the gas mixing chamber and to the chamber structure via water feed lines 64, supplied by water service feed line 65, which also feeds cooling water to the gas generator subsystem 200, from the water management subsystem 600.

The drive gas is delivered to the turbine drive subsystem 300, via discharge line 10. Thermal control of the combustion process can be accomplished by controlling cooling water flow rate to the gas mixing chamber and to the chamber structure via water feed lines 64 and 65. This embodiment is suited for sites where water availability makes the complexity and cost of a water recovery system unnecessary. The turbine drive subsystem 300, converts the gas generator subsystem 200 output energy into mechanical energy to drive the electrical generator subsystem 400. The turbine subsystem consists of three power turbines, pressure staged for optimum efficiency.
