SPECIFICATION forming part of Letters Patent No. 415,666, dated November 19', 1889.
Application filed February 19, 1889. $erial No. 300,405. (No model.)
'To all whom, it may concern: I
Be it known that I, GATEs A. CLARK, of Rochester, county of Honroe,.and State of New York, have invented an Improvement in Furnaces, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object the construction of a novel furnace especially adapted for the consumption of soft or bituminous coal and analogous material, whereby the volatile products normally contained in the coal and driven off by heat maybe consumed and a maximum amount of heat obtained from a minimum amount of fuel.
In accordance with my invention the furnace, preferably having a boiler for generating steam, is provided at its rear end with a wall extended transversely across the furnace to form a rear flue, and with a central longitudinal wall extended upward from the grate-bars to divide the furnace into two chambers, the said central wall extending, preferably, from the front wall of the furnace to the said transverse wall. The chambers formed by the central wall referred to are connected, as will be described, by fines or passages, preferably in a bridge-wall located substantially near the longitudinal center of the furnace, the said tines communicating with the said chambers, so that the volatile products generated in one chamber are 0011- ducted by one of the said fines or passages into the chamber on the opposite side of the central wall below the grate-bars therein, the said volatile products being. thus caused to pass up through the fire-bed on the said gratebars. The transverse wall at the rear of each combnstion-chamber is provided with an exit-passage controlled by a suitable damper, preferably from the front end of the furnace, and the fines or passages in the bridge-wall are preferably controlled by an independent damper.
My invention therefore consists, essentially, in the combination, in a furnace, with a transverse wall forming a rear iiue and a central wall extended upward from the grate-bar to form combustion-cha1nbers, of passages connecting each combustion chamber with the other below its grate-bars, an exit flue or passage in the said transverse wall for each combustion-chamber, and a damper to control said exit flue or passage, substantially as will be described.
' Other features of my invention will be pointed out in the claims at the end of this specification.
Figure 1 is a front end elevation of a furnace embodying my invention. Fig. 2 is a transverse section of the furnace shown in Fig. 1, the section being taken on line 00 00, Fig. 3; Fig. 3, a longitudinal section of the furnace through one of the combustionchambers on line 3 y, Fig. 2; Fig. 4, a horizontal section of the furnace shown in Fig. 1, the section being taken on line 3 3 Fig. 3; and Fig. 5, a longitudinal section through one of the combustion-chambers of a modified form of furnace.
The furnace A, having its walls composed of masonry or other suitable or usual material, and provided, as herein shown, with a tubular boiler A, extended substantially the length ofthe furnace, may be of any desired or usual construction. The furnace A is provided at its rear end with a transverse wall a, forming a rear fine or passage a. The interior of the furnace A is divided, in accordance with myinvention, into two combustionchambers a a by a central wall a extended longitudinally the length of the furnace from the front wall or end a to the transverse wall a, and also extended upward from the grate-bars. The chambers a a are connected together by means of passages Z) l) in a bridge-wall b extended, as shown, across the furnace on either side of the central wall a The passage 17 communicates with the chamher a through the top of bridge-wall in the said chamber, and is connected with the charn-- her a below the grate-bars b in the said chamber through the side of the bridgewall, while the passage 73 communicates through the top of the bridge-wall with the chamber a and with the chamber a below its gratebars b through the side of the bridge-wall, as clearly shown in Figs. 3 and 4. Each pas sage b b is provided, as shown, with a damper b suitably pivoted in the side walls of the said passage and operated from the front end of the furnace, as herein shown, through the rod 1). The combustion-chambers a a are provided with exit-fines b b in the walla, the said fiues connecting the said chambers with the rear flue or passage co, and being controlled by suitable dampers b b operated, as herein shown, from the front of the furnace by rods 5 I9 The front end of the'furnace is provided With doors 0 0', communicating with the chambers a a above the grate-bars, and with doors 0 c communicating with the ash-pits of the said chambers, the doors 0 c constituting draft-doors.
In the operation of my improved furnace a fire is started in each combustion-chamber and the dampers Z2 Z1 opened and the dampers b closed, so that the furnace may be used as an ordinary furnace until the Volatile products have been driven oif and a bed of live coals or fire created in each combus- The Volatile products now generated and driven off in the combustion-chamber a pass through the flue or passage 1) into the chamber a below its grate-bars and up through the bed of fire on the grate-bars b where they are consumed, the flame and products of combustion in the chamber a passing through the exit-passage b and the flue a, thence through the boiler to the chimney. When the volatile products from the fresh supply of coal to the chamber a have been driven off, fresh coal may be added to the fire in the combustion-chamber a and the volatile products generated therein are caused to pass through the passage or flue 1) into the com-- bustion-chamber a below its grate-bars a, the damper b in the combustion-chamber a and the damper I) being at such time closed,
while the damper b in the combustion-charm ber a and the damper b are opened, the draft-door 0 being closed and the draft-door opened. In this manner a substantially hot fire may be maintained at all times under the boiler and a maximum amount of heat obtained from a minimum amount of coal.
As shown in Fig. 3, the passage or flue in the bridge-wall and in the exit-flue in the rear wall are controlled by independent dampers;
but, if desired, the bridge-wall b may be located near the rear wall a, and the exit-passage in the rear wall and the passage in the bridge-wall controlled by a single damper, as (2, Fig. 5, controlled by a rod 6'.
I have herein shown the furnace as provided with a boiler for generating steam; but itis evident that the boiler may be omitted and the furnace used for other heating purposes.
I claim 1. The combination, in a furnace, with a transverse wall forming a rear flue a and a central wall a, extended upward from the gratebar to form combustion-chambers a a of passages 12 6, connecting each combustionchamber with the other below its grate-bars, an exit flue or passage in the said transverse wall for each combustion chamber, and a damper to control said exit flue or passage, substantially as described.
2. The combination, in a furnace, with a transverse wall forming a rear flue a and a central wall a, forming combustion-chambers a d of a bridge-wall having passages 19 b',connecting each combustion-chamber with the other below its grate-bars, an exit flue or passage for each combustion-chamber, a damper for the said. exit-flue, and a damper to control the passage in the bridge-wall, substantially as described.
In testimony whereof I have signed my nam e to this specification in the presence of two subscribing witnesses.
