Abstract:
The present invention is an oil burning system, capable of burning various waste oils with high efficiency burn, reduced emissions, and without producing sludge within the system. Generally, the system operates by pressurizing liquid fuel to a high pressure and delivering the fuel through a two-stage filtration system, pre-heating the fuel, dispensing the fuel through a nozzle and igniting the fuel.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The instant invention generally relates to an oil burning system, and more particularly to a system that is capable of maintaining high-pressure while reducing fuel usage to generate an equivalent quantity of heat as prior systems, while minimizing volume requirements of fuel and pollutants. 
         [0003]    2. Description of the Related Art 
         [0004]    With rising oil prices, consumers have become more cost and efficiency conscious. Homeowners who choose to heat their home with oil can opt to use waste oils as fuel for the heating system. However, existing waste-oil burning systems are relatively inefficient and generate a high level of pollution as these systems burn only about 75-85% of the fuel, while 15% (or more) of the fuel is not burned and is exhausted as soot plus carbon monoxide. Further, existing systems require the fuel to be heated to about 190-250° F. the heating process creates sludge in the system; this, in turn, requires disassembly of the system for cleaning, and disposal of the sludge. 
       SUMMARY OF THE INVENTION 
       [0005]    The instant invention, as illustrated herein, is clearly not anticipated, rendered obvious, or even present in any of the prior art mechanisms, either alone or in any combination thereof. 
         [0006]    The primary object of the instant invention is to produce an oil burning system that increases efficiency by reducing the amount of fuel usage through the presence of high pressure within the system, along heating the fuel under high pressure. 
         [0007]    Another object of the instant invention is to produce an oil burning system with reduced emission of carbon monoxide, hydrogen sulfates and hydrocarbons, and without creating sludge as a byproduct of operation. 
         [0008]    Another object of the instant invention is to produce an oil burning system that comprises the ability to automatically adjust the flame size to maintain a constant stack temperature to maximize efficiency. 
         [0009]    According to one embodiment, the present invention operates in the following manner: the fuel is pumped out of the storage tank by an ultra-high pressure pump which increases the pressure of the liquid fuel to approximately one thousand nine hundred pounds per square inch and passed through a two-stage high-pressure filter, into a pre-heat tank; after the fuel temperature is raised, the fuel is dispensed through a nozzle and is ignited. By monitoring the exhaust stack temperature of the system, and varying the pressure accordingly, optimal heating efficiency can be reached. Initially, when the system is cold, increasing the pressure substantially, allows the flame to burn at a higher level than that of existing systems, while not increasing the volume of liquid fuel utilized. As the water temperature of the boiler rises, the pressure is gradually reduced. Optimal efficiency is reached by monitoring the stack temperature and adjusting the pressure to keep the stack temperature at about four hundred and ten degrees Fahrenheit—the pressure is reduced when the system detects the stack temperature above four hundred ten degrees Fahrenheit. Thus, monitoring the stack temperature and adjusting the pressure accordingly allows the system to use less fuel than existing systems (i.e. as little as half a gallon of fuel per hour) to deliver the same or better temperature as a 0.85 gallon per hour system. 
         [0010]    There has thus been outlined, rather broadly, the more important features of the oil burner system in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. 
         [0011]    In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0013]      FIG. 1  illustrates a block diagram of the instant invention, wherein the system includes a storage device, a filtration system and a distribution system such that each component is in fluid communication with each other via a fuel line. 
       
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0014]    The instant invention relates to an oil burning system, and more particularly to a home heating oil booster pump system that substantially increases the efficiency and burning capabilities of existing systems by reducing overall usage of oil while maintaining the same output, along with reducing the amount of pollution created by the system. It is know in the art that most existing oil burning systems, including but not limited to home heating systems, operate at only seventy-five to eight-five percent efficiency. Thus, existing systems waste at least fifteen percent of oil burning due to incomplete burning of fuel with waste products such as soot, carbon monoxide and other pollutants. Therefore, the present system increases the efficiency of oil burning by having more completely burned fuel, along with reducing waste products during the burning process and therefore requiring less oil to generate the same amount of heat as pre-existing systems through the use of high-pressure, effective fuel flow and the elimination of the creation of any sludge throughout the process. 
         [0015]      FIG. 1  illustrates a high-efficiency oil burning system  10 , wherein the system  10  is disposed to increase the oil burning capabilities of existing systems, by maintaining high-pressure throughout the system  10  and allowing for more effective fuel flow, among other things. The overall system  10 , includes a storage device  12  for housing liquid to be used within the system  10 ; in the preferred embodiment, the oil burning system  10  utilizes number two heating oil, however in alternate embodiments the system  10  allows for the burning of a combination of number two heating oil with various other waste oil, including but not limited to biofuels and light grease, waste and virgin paint solvents, waste and virgin cleaning solvents, and diesel, kerosene and hydraulic oils. More preferably, the system  10  allows for up to fifty percent waste oil in combination with the burning of number two heating oil, wherein the waste oil may be a single composition itself, or a combination of the waste oils listed above, given that they do not comprise more than fifty percent of the overall liquid within the system  10 . 
         [0016]    The system  10  further includes a filtration system  14 , wherein the filtration system  14  substantially removes impurities from the liquid housed within the storage device  12 . The filtration system  14  comprises a pump  16 , wherein the pump  16  is in fluid communication with the storage device  12  via a fuel line  18  enabling the introduction of liquid from the storage device  12  into the filtration system  14  for high pressure purification. The system  10  also includes a first pair of filters  20  located substantially between the storage device  12  and the pump  16  of the filtration system  14 , wherein the filters  20  are in fluid communication with the storage device  12  and the pump  16  via the fuel line  18 . In the preferred embodiment, the first pair of filters  20  is arranged in a substantially tandem orientation and in a canister style. 
         [0017]    The pump  16  located within the filtration system  12  maintains high pressure throughout the system  10 , thereby creating a more efficient fuel flow throughout the system  10 , while also preventing the build-up of any sludge during the heating in the system  10 . In the preferred embodiment, the pump  16  is operable in a range of two hundred to three thousand two hundred pounds per square inch, and more preferably, the pump  16  is operable in a range of one thousand to two thousand two hundred pounds per square inch. The pump  16  includes a variable pressure control  22 , wherein the control  22  regulates the exhaust temperature or stack temperature of the overall system  10  for more efficient fuel usage, preferably around four hundred ten degrees Fahrenheit; it is know in the art that a stack temperature above this range creates waste and inefficiency within a system once the boiler is heated up to eighty percent of capacity. Furthermore, the system  10  can be automatically controlled by setting the overall stack temperature, alternatively, an individual may manually control the system set the pressure of the system for each desire fuel and burn usage. 
         [0018]    Additionally, the filtration system  12  includes a pre-heater  24 , wherein the pre-heater  24  is in fluid communication with the pump  16  via the fuel line  18 . The pre-heater  24  operates at a high pressure to maintain efficient fuel viscosity through out the system and prevent the formulation of any sludge or impurities within the liquid. In the preferred embodiment, the pre-heater  24  operates between three hundred and two thousand five hundred pounds per square inch, wherein the pressure is adjustable depending on the desired viscosity of the liquid. Therefore, the pre-heater  24  serves the purpose of heating the liquid to the desired temperature and viscosity for use in the system  10 . Moreover, in the preferred embodiment, the pre-heater  24  operates at a temperature range between seventy and one hundred ninety degrees Fahrenheit, wherein the individual utilizing the system may determine the specific temperate setting. 
         [0019]    Furthermore, a second filter  26  is disposed between the pre-heater  24  and the pump  16 , wherein the filter  26  are in fluid communication with the pump  16  and the pre-heater  24  via the fuel line  18 . Preferably the second filter  26  comprises a two stage high-pressure micron filters with mesh that allows for the removal of any liquid in a semi-solid state, thereby creating an extremely liquefied material for introduction into the pre-heater  24 . More preferably the second filter  26  operates at up to three thousand five hundred pounds per square inch to remove impurities from the liquid while continually maintaining the pressure created by the pump  16 . The second filter  26  allows for substantially clean and sludge-free passage of the liquid through the remaining components of the system and prevents clogging, while allowing for individual components to be in use longer, but most importantly to prevent sludge from building up within the system  10 . The filtration system  14  also includes an even pressure accumulator  36  as known in the art, wherein the accumulator is located substantially between the second filter  26  and the pre-heater  24 , such that the accumulator  36  is in fluid communication with the second filter  26  and the pre-heater  24  via the fuel line  18 . The accumulator maintains and ensures steady pressure distribution throughout the system  10 . 
         [0020]    Lastly, the system  10  includes a distribution system  28 , wherein the distribution system  28  is disposed to deliver the liquid to a boiler or furnace, preferably for heating a residential or commercial dwelling. The distribution system  28  further comprises a motor control  30  along with a nozzle assembly  32  for distribution of the liquid from the system  10 . The system  10  also includes a valve  34  disposed after the motor control  30  and the pre-heater  24 , wherein the valve  34  is preferably a one hundred ten volt electrical solenoid valve that is operable at up to two thousand eight hundred pounds per square inch. The valve  34  is in fluid communication with the pre-heater  24  and the control motor  30  via the fuel line, and wherein the control motor is in fluid communication with the nozzle assembly  32 . The valve  34  operates in an on and off capacity, wherein the vale is in electrical communication with the variable control  22  to regulate the overall system  10 . Moreover, a third filter  38  is located substantially between the valve  34  and the pre-heater  24  for removal of any remaining particles in the fuel or any sludge that has built up prior to distribution through the nozzle  32 . 
         [0021]    Furthermore, it is known in the art that existing oil burning systems, including but not limited to those for heating residential dwellings, create sludge during the process of oil burning and as a result, this creates two significant problems, one being that the system itself requires regular maintenance and cleaning, and two, that some of the oil in the system becomes a waste by-product thereby reducing the efficiency of the overall system. Therefore, as described above the instant invention does not require the use of a sludge collector and/or a blow down tank to remove sludge from the system since none is created by maintaining high pressure throughout the system, and additionally the second pair of filters  26  removes any remaining semi-solid particles that may have formed. Moreover, the system  10  creates a more effective flow of atomized fuel, and as a result of the lack of sludge creation, it is not necessary for the introduction of an external air supply, such as an air compressor to be incorporated into the system to atomize, clean and remove any sludge that has built up through operation. In addition, known pollutants and by-products of oil burning systems such as carbon monoxide and hydrogen sulfate are reduced substantially over current systems. 
         [0022]    Moreover it is known in the art that an oil burning system maintaining a stack temperature above four hundred ten degrees Fahrenheit creates waste and leads to inefficiency; current systems tend to operate in the range of four hundred seventy-five to six hundred degrees Fahrenheit while operating ten to twenty-five percent inefficiently. Conversely, the instant invention allows for the stack temperature to be regulated through the pressure control  22 , wherein if the system  10  generates a stack temperature above four hundred ten degrees Fahrenheit, the pressure in the system can be reduced to prevent inefficiency while also limiting oil usage. 
         [0023]    To demonstrate the feasibility of the instant invention, several tests were, performed outlining how by substantially increasing pressure throughout the entire system and monitoring the stack temperature of the system, the overall usage of oil is reduced while simultaneously maintaining output. The below examples reveal data of the instant invention versus conventional and existing oil burning systems, wherein the overall usage of oil was reduced in each instance. Furthermore, as demonstrated below, the instant invention also allows for a reduction in the pollutants given off by conventional oil burning systems, specifically carbon monoxide and hydro sulfides. 
       EXAMPLE 1  
       [0024]    To demonstrate the feasibility of the instant invention, the system  10  was compared against a two year old Burham oil burner with a nozzle possessing a dispensing capacity of nine-tenths of gallon of oil per hour. Each system was tested to determine the time and oil usage necessary to raise the water temperature of the boiler from seventy to one, hundred eighty five degrees Fahrenheit. Multiple variables were monitored during this process, including overall time lapse, the stack temperature of the system, the rate of oil usage, the pressure in the overall system and the water temperature. Table 1 represents the current system and Table 2 represents the Burham oil boiler; the tables clearly show that it takes the instant invention fifty-nine minutes and 0.62 gallons of oil to raise the water temperature to one hundred eight five degrees Fahrenheit, whereas the Burham oil boiler takes forty-seven minutes and 0.71 gallons of oil. Furthermore, as evidence from the tables, the usage rate of the instant invention dropped to-half a gallon per hour when the temperature reached one hundred eighty five degrees Fahrenheit, thereby creating a more efficient system, while also maintaining the stack temperature consistently around four hundred ten degrees Fahrenheit, thereby eliminating inefficiency as described above.

       EXAMPLE 2  
       [0025]    To demonstrate the feasibility of the instant invention, the system  10  was compared against a two year old Burham oil burner with a nozzle possessing a dispensing capacity of one and one-quarter gallons of oil per hour. Each system was tested to determine the time and oil usage necessary to raise the water temperature of the boiler from seventy to one hundred eighty five degrees Fahrenheit. Multiple variables were monitored during this process, including overall time lapse, the stack temperature of the system, the rate of oil usage, the pressure in the overall system and the water temperature. Table 3 represents the current system and Table 4 represents the Burham oil boiler; the tables clearly show that it takes the instant invention fifty-nine minutes and 0.62 gallons of oil to raise the water temperature to one hundred eight five degrees Fahrenheit, whereas the Burham oil boiler takes forty-three minutes and 0.89 gallons of oil. Furthermore, as evidence from the tables, the usage rate of the instant invention dropped to half a gallon per hour when the temperature reached one hundred eighty five degrees Fahrenheit, thereby creating a more efficient system, while also maintaining the stack temperature consistently around four hundred ten degrees Fahrenheit, thereby eliminating inefficiency as described above.

       EXAMPLE 3  
       [0026]    To demonstrate the feasibility of the instant invention, measurements for both the level of carbon monoxide and hydro sulfides existing the various systems were taken and shown in detail below. Table 5 represents the instant invention at different fuel usages; Table 6 represents the Burham oil boiler with different nozzle assemblies and usages, exhibiting existing home heating oil systems. As the below data clearly illustrates, the amount of pollutants released by the instant invention is dramatically reduced in comparison to existing systems.
