Specification of Letters Patent.

Application filed August 6. 1906. Serial No. 329.273.
are to properly mix a proper quantity of air with the gas to promote complete combus;-
tion and cause the combustion to proceed at a proper rate, to completely burn such gaseous fuel, to cheapen and simplify the construction of the furnace, to produce a llame adapted to special uses, and to generally improve theconstruction of furnaces for the purposes hereinafter set forth. These ob- ]ects and other advantages are gained by the construction lillustrated in one form in the accompanying drawings, wherein- Figure 1 is a partial perspective and a vertical transverse section of the furnace; and Fig. 2 is a horizontal section of the same, taken on the line 2 in Fig. 1.
It has ordinarily been 'practically impossible to burn producer-gas in furnaces such as used for boilers or for annealing in glasshouses, &c., and especially to do so with the natural draft of air. Not only has it been found impracticable to get suflicient quantity of air at exactly the right place, but if such result was obtained the burning took place immediately at the outlet of air and the flame was hottest at a point where the heat was not needed and rapidly dissipated as the flame approached the obJect to be heated. In 4 order to overcome these difficulties, it will be seen that I have provided under the object to be heated (Which in this case is the annealing-chamber a) a combustion-chamber b, having a flat perforated floor. Centrally located beneath the floor and chamber b is a gas-supply chamber c', which may be connected directly with a sewer or other conductor f, introducing the producer gas through a convenient' valve g. On each side of the gas-chamber c is an air-chamber c, which is preferably of nearly double the size of -the gas-chamber and is fed by natural draft by simply leaving the end of chamber c open or by means of numerous openings'm through the side of the furnace. The gas-chamber c has' a series of small slots in its top e, which are preferably of converging form, as shown, and in close proximity to them are a series of slots d, similarly converging and opening vthrough the top of the airpassages c. It Will be observed from Fig. 2 that these slots open near each other and that the slots e and d are made in sizes correy spending tothe proper proportions of air and gas, which are ordinarily about two to one; also, that the pairsof cooperating openings'd e are staggered with respect to the `median line o f the gas-chamber, so that the llames burning on the floor of the chamber b alternate with each other, so as not to interfere. The flame after complete combustion in chamber b passes through the passages k into the leer or under a boiler or to any other place where the heat is to be applied.
It will be seen that in this construction the numerous flames burn on a flat floor in the chamber b and that the4 gas in passage from openings e to outlets 7c must pass through a t in sheet of air rawn through the slots d.
The result is to thoroughly mix an amply suf-- I'icient quantity of air with vthe. producer-gas and give the flame time to reach the assages k before its highest heat is reached.) Thus the smoke is entirely burned out of the gas and a pure flame is secured, as Well as the maximum amount of heat which can be obtained from the burning of the quantity of gas. The construction is cheap and simple,
so that the accurate desi ning usually neces-- sary in such furnaces is o viated.
While I have illustrated the construction as applied to a glass-annealing leer, it will be understood, of course, that the invention is clearly applicable to steamy-boilers or any other position Where a furnace is to be used for burning producer-gas. Various advantages of the invention will vreadily occur to those familiar with the art.
Having thus described my invention and illustrated its use, what I claim is newand desire to secure by Letters Patent, is the folloWin 1. furnace comprising a combustionchamber, a gas-chamber underneath the same having narrow slots opening through its top, and an air-chamber lyin closely contiguous to the gas-chamber and iaving corresponding narrow slots opening through its top in close proximity to` saiil gas-outlets, whereby the air and 'as are mixed ilnrnedi` ately at their outlet from the supplynchambers.
2. A furnace comprising a combustionchamber With a flat loor, a' centrally-located relatively large gas-chamber under sai-d Hoor and communicating therewith through a series of narrowv slots; outlet-passages for the flame and a heating-chamber, and a pair of natural-draft air-passages close to and on the sides of the gas-chamber and having slots opening through said floor in -closeproximit to the gas-outlets, substantially as describe '3. Aurnace for produceras comprising a flat-bottomed combustion-c iamber a gaschamber beneath and o ening through said floor by narrow slots ani air-chambers on the sides of the gas-chamber, fed by natural draft and openin into the combustion-chamnesses.
