FUEL-OIL BURNER.
Specification of Letters Patent.
Patented Nov. 16, 1915.
Application filed March 27, 1915. Serial No. 17,354.
To all whom it may concern Be it known that I, James H. KRAMER, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Fuel-Oil Burners, of which the following is a specification.
This invention relates to fuel oil burners of the injector type, and its object is to provide a simple and highly etficient burner of this kind, characterized by a mixing chamher into which. are delivered, by an injector action, oil and steam or air under pressure, and from which chamber the mixture is discharged into the combustion chamber of the furnace.
The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is an elevation of the apparatus, partly in sectiomand Fig. 2 is a plan view thereof.
Referring specifically to the drawing, 5 denotes an injector nozzle which is connected at its inlet end to a valve casing 6 containing a valve 7, and having a connection 8 with a source of fluid under pressure, such as steam or air, and in which connection is interposed a valve 9. The discharge end of the nozzle is connected to one end of a. T-coupling 10, to
the opposite end of which latter is connected a delivery pipe 11 leading to a mixing chamber 12 of large diameter and'having contracted ends. To the side of the coupling 10 is connected a pipe 13 leading from a suitable source of oil supply and containing a valve 1%. To the outlet end of the mixing chamber and in alinement with the delivery pipe is connected a nozzle 15 having itsdischarge end located to discharge into the combustion chamber of the furnace.
In operation, when the fluid under pressure and oil is turned on by opening the valves 9 and 14, the steam, air, or other fluid under pressure is discharged from the nozzle 5 through the coupling 10 and the pipe 11 into the chamber 12 The oil discharges into the coupling 10 in frontof the nozzle 5 and is blown and carried along with the steam or air, and both are injected into the chamber with a high velocity and under pressure, and the mixture is discharged into the furnace combustion chamber through the nozzle 15, and upon being ignited it burns fiercely and with intense heat. The oil will be fed into the coupling 10 under a pressure a little below the pressure of the air or steam, a difference of ten pounds in the respective pressures giving good results. The steam or air and the oil are thoroughly mixed by the impact and the atomizing action produced. by r the discharge of steam or airfrom the nozzle 5 in direct contact with the oil, and a further and complete mixture takes place in the chamber 12.
The injector pipe 5 is connected to one end of the casing 6, and in the opposite end of the latter is a clean-out opening 16. The steam or air supply-connection 8 is made at the side of the casing. The valve 7 is so constructed that it closes the opening 16 when the apparatus is in operation, and it can be turned to uncover said opening, and as the latter is in line with the injector nozzle, the same can be easily cleaned out.
The burner can be operated with wet or dry steam, or compressed air. A perfect mixture and absolute combustion is assured. The burner is also non-choking, and is adapted for either heavy or light oils. In view of the simplicity of the structure, the burner can be easily and cheaply manufactured. and it is alsoeconom cal in fuel consumption. The burner produces an intense I discharge directly front of the end of said outlet nozzle being of small diameter to fit l0 nozzle, a delivery pipe connected to saidcoupllng H1 allnement With said nozzle, a mixsaid contracted ends,
