Title: Apparatus and method for starting a forced through flow vapour generator and associated power plant
IPC: F22B37/48
Filed: 1964-03-18
Abstract: A method of starting a forced flow once through steam generator and associated power plant operating at or above critical pressure including a feedwater heating system and a furnace lined with steam generating and superheating tubes consists of clean-up of preboiler equipment between the condenser and economizer, clean-up of economizer and furnace tube walls, clean-up of superheating section and warming, rolling and synchronizing the associated turbine plant. During this start up a major portion of the fluid input through the generating tubes is recirculated to provide protection against overheating. The working fluid is circulated by a turbine-driven feed pump 22 and a boost feed pump, Fig. 3 (not shown), through H.P. feedwater heater 24, steam operated feed valve 26, economizer 21, furnace tube walls 30a, 30b, boiler throttle and boiler throttle by-pass valves 32a, 32b, superheater 33, H.P. turbine 36, reheaters 38, 39, L.P. turbine 40 and condenser 10. Condensate is circulated by pump 12, through a filter and demineralizer 14, L.P. feedwater heater 18 and deaerator 16. Water of acceptable purity is supplied from a make-up tank 11 leading to the condenser 10 and the concentration of impurities such as copper and iron in the water is measured by chemical analysis equipment 33a, 33b, 33c, 33d. Fluid is recirculated by pump 28 through the furnace tubes 30a, 30b, via conduit 46. A flash tank 44 is connected, in parallel across valves 32a, 32b by conduits containing valves 42, 51, to the feedwater supply line by conduit 41 containing valve 37 and to the condenser by conduit 50. An auxiliary boiler 20 supplies steam for turbine seals, the deaerator 16 and for the initial operation of pump 22 and valve 26. The method of starting commences with preboiler clean-up comprising closing valves 26, 42, 51, filling the preboiler equipment with demineralized water and circulating it by pumps 12, 19 through the equipment and conduits 41, 45. Both feedwater heaters comprise two parallel heaters arranged so that the entire flow can be passed through each heater separately to increase the speed and efficiency of clean-up. When the impurities are reduced to an acceptable value, e.g. 20 p.p.b. boiler clean up is commenced by firing the boiler and circulating about 5% of maximum feed water flow through the economizer and tubes 30a, 30b, the flash tank 44 and the condenser, valve 42 controlling the pressure at which is gradually raised from 1000 to 3500 p.s.i.g. L.P. steam from tank 44 is passed through the superheaters for cooling and when it is sufficiently pure is passed from the tank through superheaters 38, 39 to the turbine to roll and synchronize it, the firing rate being gradually increased.

The different operating conditions in the two zones may be achieved by using different catalysts, temperatures, pressures or flow rates, by regulating the quantity of ethylene and vinyl chloride mixture reacting before it reaches the exit from the first zone, by using zones of different crosssections, by regulating the molar ratios of the reactants or by using catalyst supports having different average specific surface areas. Specified catalyst supports are silica, silicates, clays, alumina, aluminosilicates, magnesia, graphite or alumina. Pentachloroethane may be produced as a by-product.
Patent ES-360101-A1 (ES)
Title: Apparatus for topping and delimbing trees
IPC: A01G23/085
Filed: 1968-10-25
Abstract: Apparatus for delimbing trees comprises a head 50, Fig. 1, delimbing blade means 52, 54 mounted on the head for movement relative thereto, means for moving the head along a tree to be delimbed, means connected to the head and the moving means for developing a fluid pressure due to movement of the moving means, and means responsive to the fluid pressure to move the blade means. In the apparatus described a tree T which has been gripped by jaws 32, 34 and cut by blades 36 is lifted by a boom assembly 16 on to a platform 14 where it is held by jaws 40, 42. The head 50 is then drawn upwardly along the length of the tree to delimb it, the movement being effected by a cable 72. As shown in Fig. 6 the cable 72 is connected to rods 104, 106 provided with a piston 108 which slides within a cylinder 110 carried by the head 50. As the head 50 is pulled downwardly by cable 72 pressure is exerted on a fluid in the lower part of the cylinder 110 so that a fluid flow is created in conduits 112, 116, 120, 122 and 134. Such flow results in withdrawal of pistons 63 in cylinders 62, 64 so that the delimbing blades 52, 54 are pivoted away from each other. The flow in conduit 134 causes tree topping blades 86, 88 linked to the piston 139 of a cylinder 136 and also carried by the head 50 to be moved to their inactive position shown. The movement of pistons 63 and 139 also causes fluid flow in conduits 130 and 140 which results in the storage of fluid energy in accumulators 132, 152. When the head 50 is subsequently pulled upwardly, the piston 108 is raised in the cylinder 110 so that the fluid energy stored in accumulator 132 is released to move the delimbing blades towards each other as they move up the tree. When the blades reach a certain position, corresponding to a predetermined tree diameter they actuate a roller 146 thus opening a valve 142 and releasing fluid energy from the accumulator 152. This causes the blades 86, 88 to be pivoted towards each other to top the tree.
