FURNACE.
SPECIFICATION forming part of L'etters Patent N 0. 669,978, dated March 19, 1901.
Application filed August 3, 1900.
To all whom, it may concern:
Be it known that I, LAMBERT BROUHON, engineer, a citizen of Germany, residing at 1 Lutticherstrasse, AiX-la-Ohapelle, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My present invention consists in an improved consi ruction of a furnace and arrangement "of its parts so that it can be used in any kind of boiler plants; and the object in view is saving of fuel and consuming of smoke.
In the accompanying drawings, Figure l is a front view of my invention attached to a head of a boiler. Fig. 2 is a horizontal section of my invention, apart of the flue not shown in section; and Fig. 8 is a top plan view.
The novelty of my invention consists in providing the combustion -chamber attachment at with one or more back-draft flues Z), connected by means of secondary channels 0 with the smoke-stack (not shown) in the shortest-way possible.
By means of this arrangement the velocity of the gases,which in the ordinary way escape beyond the fire-grate d, is checked, and the flames cannot escape toward the smoke-stack in an inclined position, as hitherto, but are compelled to remain for a longer space of time in ,a vertical position over the grate, so that the suspended particles of coal find time to fall back upon the fire, and the otherwise uselessly carried off carbonic acids are comheat.
The area of the flue or flues I) does not need to exceed the area of the fire-door e, but must be smaller than the area of the main flue just beyond the fire-grate d. The draft in the flue b can be suitably regulated by means of a damperf, which must be set to suit each individual case.
In operation the damper f, suitably mounted on the rod 9 in flue b, is turned by means of thelever it, also mounted on the rod g, and chains 11 and 7c. The chain 2' is fastened to a disk Z on the bar m, forming the pivot of the door 6, which shows a well-known construc- $erial No. 25,800. (No model.)
tion,while chain 7a runs over a sheave 17.,mounted in a bracket 0 on flue Z), and carries the weight 13. Now it is clear that when the door c is opened the damperf takes up a position, as shown in Fig. 3, giving to the fine I) the largest possible area, and the cold air, entering through the door 6 while fuel is thrown in will of necessity be drawn off through the line 1) without coming into contact with the fire upon the grate nor have a chance to cool off the walls of the combustion chamber proper.
Under the door 6, Fig. 1,'and under the (J5 grate the door qis pivotally attached to give admittance to the ash-pit. Within the attachment a there is a shell 9', with openings corresponding with the doors 6 and q and one to correspond with the flue 1). Between said in the main fine and in the smoke-stack is lowered considerably and the draft checked just at the time when excessive smoke is forming, so that the fine particles of coal-dust remain in the combustion-chamber and havea chance ofgetting burned. As soon as the door e is closed the temperature in the main flue and smoke-stack risesagain, and the combustion is gradually carried on in the abovementioned manner until a new supply of fuel demands the opening of the fire-door once more. In this manner the draft is automatically regulated throughout the working of the plant.
I claim- 1. In a smoke-consuming furnace, a combustion-chamber attachment a provided with a fine I] to lead off the cold air when fuel is thrown in, a damperf in said flue giving the maximum area of the flue free when the door 6 is opened and diminishing said area when said door is shut, a lever h fastened to the prolonged rod g of said damper and connected with said door and to a weight 19 by means of chains 2', 7a and a shell within said attachment with openings to correspond with said doors too and with said flue and a horizontal divisionplate to separate the combustion-chamber from the ash-pit, substantially as described. 2. In a smoke-consuming furnace, in com- 10 a sheave n mounted in a bracket 0 on flue b,
and a shell Within said attachment a, substantially as shown and described.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
LAMBERT BROUHON.
