SYSTEM FOR SUPPLYING LIQUID FUEL TO BURNERS.
Specification of Letters Patent.
Patented Nov. 2-, 1920.
Application filed March 6, 1920. Serial No. 363,725.
To all whom it concern 7 Be it known that I, l/VILLIAM N; BEST, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Systems for Supplying Liquid Fuel to Burners, of which the following is a specification.
This invention is an improved system for supplying liquid fuel to burners and is intended primarily for viscous oils or other fluid fuels which, by reason of high viscosity, do not flow freely through the supply pipes at atmospheric temperature or at the particular temperature at which the fuel is or may be stored. The liquid fuel is burned to heat a low pressure steam boiler and, as an important feature of my invention, I maintain a circulation of the boiler water, heated by the burning fuel, in heat interchanging relationship with the tank supplying fuel to the burner of the boiler. Thus a portion of the heat of the burning fuel is utilized for maintaining the fuel in such condition that it may be conveniently delivered to the burner.
As a further feature I maintain a continuous circulation of the fuel as well as of the boiler water, utilizing a single source of power for maintaining both circulations.
In the accompanying drawings I have illustrated, somewhat diagrammatically, one form of apparatus which may be utilized for carrying out my invention but obviously I do not care to belimited to this specific construction.
In these drawings:
Figure l is a top'plan view; and
Fig. 2 is a side elevation.
I have illustrated my invention in connection with a low pressure steam boiler 10 of any suitable construction and having a fire chamber 11. The details of the boiler have not been illustrated as they form no portion of my invention. For heatingfthe boiler I have illustrated, somewhat diagrammatically, a burner 12 which has a liquid fuel supply pipe 13 and a compressed air supply pipe 14 connected thereto. The burner has outlets so juxtaposed that the compressed air escapes across the fuel outlet and delivers a spray of the fuel into the combustion chamber. The burner itself forms no portion of my present invention,
but may be constructed as illustrated in my prior Patents 708,453 issued September 2 1902 and 752,195 issued February 16, 1904. The liquid fuel may be stored in any suitable receptacle at the proper distance from the burner. 1 have illustrated a tank 15.
In carrying out my invention I provide the tank with steam passages in heat interchanging relation thereto. I have illustrated a hot water coil 16 having one end connected to the boiler below the water line thereof by a pipe 17 and the other end also connected to the boiler below the water line by a pipe 18. In one of these pipes, preferably the pipe 18 leading from the boiler to the coil, 1' insert a suitable water circulating pump 19. This is of rotary form and may be of any suitable type. The pump serves to continuously withdraw water from the boiler, circulate it through the heating coil 16 and return it to the boiler through pipe 17.
' The oil is withdrawn from the tank by a pipe 20 and delivered by a rotary pump 21 through a pipe 22 and back to the tank through a pipe 23. The pipe 1 3 delivering oil directly to the burner, communicates with the pipe 22. and thereis preferably a pressure relief valve 24 at or adjacent to this point. The pump 21 thus continuously circulates oil and the burner; is suppliedjwith oil under comparatively low pressure from this circulating pipe. Obviously there may be any desired number of burners with corresponding branch pipes 13 from the oil circulating system. Where the system is used with a boiler producing low pressure steam, the vaporizing or spraying of the oil is preferably accomplished by a pressure blower 25 which may also be of a rotary type and which takes air from the atmosphere and delivers it through a pipe 26 to the air intake 14 of the burner. As a simple means for operating the water and oil pumps, and the pressure blower, I may mount them coaxially and drive all of them from a small electric motor 27 or other suitable source of power.
Although the invention, as illustrated, is particularly useful for boilers having low pressure steam such, for instance, as two (2) to ten (10) pounds, it would be obvious that it might be employed with higher pressure boilers. The blower is preferably a positive blower designed to give the required amount of air pressure for the vaporlzation of the Oll and the distributlon of the heat withln the fire chamber. The
oil pump is preferably such as will keep the burner properly supplied and maintain a small oil pressure, for instance, about five (5) pounds in the pipe 22, the pressure are lief valve 2 f acting automaticallyto prevent a higher oil pressure and to permit the excess to return to the tank.
In starting the apparatus the boiler may be initially heated in any suitable manner as, for instance, by building a fire of solid fuel in fire chamber 11 until the water raised to such a temperature that, when circulated through the heating coils of the tank, it will reduce the viscosity of the fuel and permit the free circulation of the latter. The circulating system may then be started. The fuel burning at the burner 12 serves not only to generate steam in the boiler but a portion of the heat is utilized in keeping the liquid fuel in such condition that it may be freely and continuously delivered to the burner. It is important that water be taken from the boiler for this heating purpose and from a point below the page or by-passing may occur when the valves 28 are closed.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. In combination a steam boiler, a liquid fuel burner for heating same, a liquid fuel supply tank, means for delivering liquid fuel from said tank to said burner, and means for circulating water from and to the boiler in heat interchanging relationship to said tank.
2. In combination a steam boiler, a liquid fuel burner for heating the same, a liquid fuel tank having a heating coil, means for circulating water through said coil and boiler, and means for delivering liquid fuel from said tank to said burner.
3. In combination a boiler, a burner for heating the same, a storage tank for viscous fuel, a heating coil in said tank, means including a pump for circulating water through said coil and said boiler, a liquid fuel circuit including a pump and supply and delivery pipes connected thereto and to said tank, and means fordelivering oil from said oil circuit to said burner.
t. In combination a low pressure steam boiler, a burner for heating the same, a supply tank for viscous fuel, means for delivering fuel from said tank to said burner, and means for reducing the viscosity of the fuel including a heating coil in the tank and connections including a pump between said coil and said boiler below the water level of the latter.
