SPECIFICATION forming part of Letters Patent No. 536,902, dated April 2, 1895.
Application filed November 30,1894. Serial No. 5 30.394. (No model.)
i all! whom it may concern.-
Be it known that I, WALTER WALLACE TVAINRIGHT, of Palestine, in the county of Anderson and State of Texas, have invented a new and Improved Furnace, of which the following is afull, clear, and exact description.
The object of the invention is to provide a new and improved furnace, which is comparativelyslmple and durable in construction, very effective in operation, and arranged to utilize the fuel to the fullest advantage, insure complete combustion and prevent the escape of smoke and obnoxious gases.
The invention consists of a connection between the chimney or stack and the fire-box,
and a suction fan located in the said connection, to draw the gases from the stack and force the same into the burning fuel in the fi rebox above the grate bars.
The invention also consists in certain parts and details, and combinations of the same, as
, will be hereinafter fully described and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the Views.
Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a plan view of the same with parts in section. Fig. 3 is a transverse section of the same on the line 33 of Fig. 2; and Fig. 4 is a sectional plan View of part of the same, on the line 4-4 of Fig. 3.
The improved furnace as illustrated in the drawings, is provided with an ordinary return flue tubular boiler A, set in the usual manner in the brickwork B containing the fire box 0. The stack A is provided with a damper D, under the control of the operator, to regulate the outlet for the gases through the stack.
On the stack A, and directly below the damper D, is arranged a suction pipe E,connected with a suction fan F of any approved construction, and preferably located on top of the boiler A, and driven from suitable machinery. The dischargepipe G of this suction fan F connects by two transverse branch pipes G and G2 with vertically disposed channels E and B formed in the side walls of the brickwork B, as plainly indicated in Figs. 3
and 4. The lower ends of the channels B and B terminate in horizontally extending chambers B and B respectively, containing skeleton frames H and H respectively, having a number of openings discharging into the fire box 0, a few inches above the grate bars in the said fire box. Into the chambers B and B extend feed water pipes I and 1 respectively,
adapted to be heated by the discharge of the gases through the said chambers, to heat the feed water previous to passing it into the boiler.
The operation is as follows: When the fuel is burning in the fire box C, and the damper D is closed and the exhaust fan F is set in motion, then the gases arising from the fuel. burning in the fire box are drawn through the boiler flues into the lower part of the stack A to the suction pipe E, by the action of the exhaust fan F. Thelatter discharges the gases, smoke, dzcl, by the pipes G, G and G into the channels B, B and chambers B B, from which the said smoke and gases are discharged directly into the burning fuel in the fire box 0, to be consumed therein. Thus it will be seen that the smoke and gases are quickly returned to the fire box, to be burned in conjunction with the fuel burning in the said fire box, and no valuable properties Whatever are lost by escaping .through the stack A into the open air or chimney. At the same time a proper draft is obtained in the furnace as the gases and smoke can readily circulate by the means described, and consequently a proper burning of the fuel in the fire box is obtained.
When applied to locomotives the exhaust steam ofthe engines passes with the smoke and gases to the fire box, so that the heat in the fire box is greatly increased owing to the oxygen in the steam.
For stationary boilers and engines the exhaust steam of the engine is passed directly into the throat of the suction pipe for the fan.
It will also be seen that the device completely arrests all sparks. 1
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- In a furnace, the combination of a casing having a fire-box, a grate, a stack, and cham- 10 gether, said breeching being connected to the stack and a suction-fan located in the breeching and adapted to draw the gases from the stack and force the same through the vertical flues into the fire box, substantially as set forth.
WALTER WALLACE WAINRIGHT.
