FURNACE.
SPECIFICATION forming part of Letters Patent No. 581,179, dated April 20, 1897. Application filed December 11, 1895. Renewed September 25, 1896. Serial No. 607,003. (No model.)
To all whmn it may concern.-
Be it known that I, SEYMOUR G. SMITH, of Plainfield, in the county of Union and State of New Jersey, have invented a new and Improved Gas Generating and Utilizing Furnace, of which the following is a full, clear, and exact description.
The invention relates to smoke and gas consuming furnaces; and its object is to provide a new and improved furnace which is simple and durable in construction, very effective in operation, and designed for consuming and destroying foul air and odors generated in gasworks, slaughter-houses, limekilns, and in all factories and places where objectionable or dangerous gases are generated; also, to consume all smoke produced by any kind of fuel-such as soft coal, shavings, sawdust or -woodor arising from the cremation of garbage or from blast-furnaces, &c. without permitting any of the smoke, gases, &c. to escape into the air.
The invention consists principally of a condensing and gasifying chamber adapted to be heated, and formed with jet-openings leading into the combustion-chamber of the furnace.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
1 Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.
Figure l is a longitudinal section of the improvement on the line 1 1 of Fig. 2, and Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1.
In the brickwork A of the furnace is arranged a fire-box B, provided in its bottom with a grate 0, below which is arranged an ash-pit D. A fuel-charge door E leads to the fire-box B to permit of introducing coal or other fuel into the fire-box to be burned on the grate O. The ashes passing through the grate-bars fall into the ash-pit D and can be removed therefrom from time to time through an ash-door E.
Into the ash-pitD open the jets D,connected with a chamber D connected by a pipe D with a suitable air-blast for insuring a suflicient introduction of air into the ash-pit and to the fuel burning on the grate O to cause a proper combustion of the fuel. The boiler F is supported in the usual manner in the brickwork A, and said boiler extends with its forward part into the fire-boXB, so that the burning fuel and gases heat the boiler, it being understood that the products of combustion pass over the bridge-wall G, under the boiler F,into a consuming-chamber H, arranged under the rear of the boiler F and in the rear of the bridge-wall G, and leading at its bottom part, by an opening I in the-lower end of the wall 1, into a chamber J, extending with its upper end to the rear end of the boiler F to permit the heat to pass through the fines in the boiler and through said fines to the stack K, arranged at the forward end of the boiler, as plainly indicated in Fig. 1.
The foul air, smoke, gases, and the like to be consumed are passed, by means of a pressureblower L, into the leg N of a condensing and gasifying chamber N. formed in the top and around the brickwork A, over the front part of the boiler F, as plainly shown in the drawings. This chamber Nis formed with a second leg N in the side of the brickwork A, opposite to that in which the leg N is located. The lower ends of the legs N N 2 connect with longitudinallyextending chambers N 3 N respectively, formed in the sides of the brickwork A, and connect with each other at their rear ends by a transverse channel N arranged in the bridge-Wall G. From the side chambers N N 4 lead jet-openings N into the fire-box B, a suitable distance above the grate O, and like jet-openings N lead from the channel N into the rear end of the fire-box, as plainly indicated in the drawings.
Now it will be seen that the foul air, smoke, gases, and the like to be consumed and forced into the condensing and gasifying chamber N pass from the latter through the jet-openings N and N into the fire-box Bin a heated condition, to be burned in the fire-box with the fuel burning on the grate O. The foul products and the gases generated in the chamber N are burned in the fire-boXBand chamber H, from which the products of combustion (hot air) pass through the openinglinto the chamber J, and through the fines in the boiler F to the stack K.
Now in order to utilize the heat of the gases in the consuming-chamber II in addition to heating the boiler F, I provide the said chamber with a feed-water pipe 0, preferably arranged in the form of a coil and connected at its lower end 0 with a pump or other feedwater supply. The upper end 0 of the coil of pipe extends forwardly over the bridgewall If and under the boiler F to pass through the front wall of the brickwork into the lower end of the smoke-stack K, to then connect at O with the watercompartment of the boiler F.
Now it will be seen that by the arrangement described the feed-water passed through the pipe 0 is heated to a high degree before itpasses into the water-compartment of the boiler F. I prefer to introduce live steam and air into the condensing and gasifying chamber N, so that the steam and air are heated to a high temperature and combine with the foul air, smoke, and odors forced through the chamber by the pressure-blower L, connected with the log N. In the suctionpipe L of the blower L for the leg I is arranged a valved air-inlet pipe L for drawing fresh atmospheric air into the said blower L to mix with the foul air. Steam is introduced into the chamber N by a pipe P, preferably connected with the steam-compartment of the boiler F and discharging into the outlet of the blower L. Thus foul air, smoke, or gases and fresh air and steam are mixed and pass together into the chamber N. By this arrangement a liighlycombustible gas is generated within said chamber N, and the gas passing through the jet-openings N N is burned within the fire-box B with the fuel burning on the grate C. The intense heat thus generated by the consumption of the gases permits of heating the water in the boiler F very quickly, so as to insure a high steampressure in the boiler at a small consumption of fuel on the grate C.
If the device is applied to large plants, a very large percentage of the fuel can be saved, as the heat obtained by the burning of the gases in the fire-box Band chamberll is very great and can be utilized for the purpose of heating the water in the boiler and the feedwater before the latter enters the boiler. All odors, smoke, and the like generated by burning or treatment of any vegetable, mineral, or organic matter can be reduced to an inoffensive and practically sightless substance, thereby removing any objectionable or dangerous odors or smoke now passing into the air. It is well. known that onlyabout twentyseven per cent. of the actual combustion is utilized, but with my process a much larger percentage is made effective, and consequently a larger saving in the coal consumed is obtained.
By placing the pipe 0 for the feed-water in the gas-consuming chamber II, I am enabled to utilize the heat generated by burning the waste gases, and the pipe cannot be fouled on the outside, as no cinders, soot, or
other solid particles come in contact with said pipe, as all such solid mat-tor is 0011- densed and gasiiled in the chamber N and burned in the fire-box l3 and chamber II, as before described Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A furnace, consisting of acasing having a fire-box in communication with a consuming-chamber, the casing also having a condensing and gasifying chamber comprising two legs straddling the fire-box and communicating at their lower ends with side chambers connected by a transverse channel, the chambers and channel having jets delivering into the fire-box, a boiler located above the firebox and eonsuming-chamber, a blower delivering into the condensing and gasifying chamber, and a steam-pipe leading from the boiler to the blower, substantially as described.
