SPECIFICATION forming part of Letters Patent No. 588,630, dated August 24, 1897.
Application filed May 8,1897. Serial No. 635,660. (No model.)
To all whom, it may concern.-
Be it known that 1, WILLIAM BROTHERS, a subject of the Queen of Great Britain, residing at Rawtenstall, in the county of Lancaster, England, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.
This invention is designed to provide for the more complete combustion of fuel in furnaces for heating steam-generators or other boilers, kilns, ovens, stills, vats, retorts, saltpans, chemical-furnaces, and other descriptions of furnaces, resulting in the increase of heat duty obtainable from the fuel and the prevention or almost entire abatement of smoke at the chimney, in addition to the entire or nearly entire absence of the noxious carbonicoxid gas at the exit. 1
It will be fully described with reference to the accompanying drawings, in which, as an example, the furnace is illustrated as applied to a steam-boiler.
Figure lis a front elevation; Fig. 2, atransverse section on line 00 00, Fig. 4 Fig. 3, a transverse section through the combustion-chamber on line y y, Fig. 4; Fig. 4, a longitudinal sectional elevation showing furnace in front of steam-generator fiues; Fig. 5, a sectional plan of same; Fig. 6, a longitudinal section showing furnace fitted in the interior of steamboiler flue; Fig. 7 ,a transverse section of same.
The furnace, which is of fire-bricksor other suitable material and of any desired size or dimensions, is constructed, preferably, with two furnace-chambers A to receive the fuel. It is preferably of curved or dome shape at top, with a partition-wall B and grate or fire bars 0 placed over an ash-pan D, said ash- Behind the f urnace-chambers A (or in such a position as to be between the furnaceand the boiler or other appliance to be heated) are constructed combustion-chambers E. The combustion-chambers E are preferably domeshaped, similar to the furnace-chambers, and divided by a partition-wall e and provided with exit-openings 6, leading into the flue of the boiler to be heated.
Above or around the furnace-chamber A are formed air chambers or passages F, through which all the products of combuscomplete the combustion are passed to the combustion-chamber E. The air-chambers F, being situated above or around the furnace, are heated by the heat passing through the walls, as well as by the heated gases from the furnace A.
In the sides of the furnace or furnacechambers A are provided a number of openings or ports G, (preferably situated at a level near the grate-bars,) which connect the interior of the furnace-chamber with passages H, through which the products of combustion pass into the air-chambers F.
All the gases generated from the fuel in the furnace-chambers A are caused to pass through the openings G into the air chamber or chambers F, where they mingle with a fresh supply of air and in which the combustion continues. The furnace-chambers A have preferably no other outlet or inlet, with the exception of the charging-doors K and the fire-bars C.
The air-chambers F are provided withairinlets f, placed in the front of the furnace or other convenient position, through which any desired or regulated quantity of air is admitted sufficient to-promote the complete combustion of the products from the furnacechambers A. The inlets fare preferably situated in front, but may be at the top or sides or other suitable position.
The admission of air through the inlets f is regulated by pivoted doors or flap-valves or other regulators M. These regulators are set so as to allow the desired amount of air into the chamber F. I
To provide against an inrush of air into the furnace or furnace-chambers Awhen the furnace door or doors are opened for any purpose, the regulators M are connected to the doors K by a chain 0 passing around a pulley 0 on the pivot kof the door or by rods or other mechanical contrivance, so as to open with the furnace-door K and check the draft through the furnace.
The air chamber or chambers F open into the combustion-chambers ;E, into which are delivered all the products or gases from the furnaces as well as the air admitted through the air-chambers, and in this chamber E a complete combustion is effected at avery high temperature, the heated gases passing out through the outlet-openings e to the interior of the steam-boiler P or other apparatus or structure where heat is required.
In addition to the inlets f for admitting air into the air-chamber F one or more apertures f maylead direct into the combustion-chamber E. The apertures f may be provided with regulators to admit a further supply of air direct into the combustion-chamber, if required.
The invention may, if desired, be placed entirely within the shell of the boiler or structure, as shownin Figs. 6 and 7, the apparatus being of similar construction, or it may be placed in any other convenient position.
The main features of the invention consist in the construction of the furnace and of the air-chamber and combustion-chamber, into which latter all the products and gases of partial combustion pass, with a regulated supply of air sufficient to promote therein secondary and complete combustion, whereby a' very.largely-increased heat from the fuel and an almost entire abatement of the smoke nuisance are obtained,and also a nearly complete (if not wholly complete) absence of the noxious and wasteful carbonic-oxid gas at the exit.
In operation the fuel is thrown or fed into the furnace or furnace-chambers A upon the burning fuel therein, a regulated amount of air being admitted to the fuel through the firebars C. Hydrocarbon, carbonic oxid, and carbonic-acid gases are produced or generated, and these gases pass through the openings or ports G and passages H into the airchamber or air-chambers F, and are there supplied by the inlets f with such regulated amount of air as is necessary for the complete combustion of the heated gases. The heated gases and the supply of air which has been admitted into the air-chamber are passed into the combustion chamber or chambers E, where an additional regulated amount of air may, if required, be admitted. In the air chamber or chambers F and in the combustion chamber or chambers E the gases originally produced in the furnace or furnaces A undergo secondary or more complete combustion and attain a much greater degree of heat than when they left the furnace or furnaces A, the combustion being so perfect that little or no carbonic oxid is observable at the exit.
The opening of the air-inlets F simultaneously with the opening of the furnace-doors for supplying fresh fuel or for removing clinkers permits of the chimney-draft acting but little upon the furnace-chambers A, and so draws but little additional air through the furnace, the chimney-draft being mainlysatisfied with the extra amount of air supplied for the time being through the air-inlets f.
What I claim as my invention, and desire to protect by Letters Patent, is-
1. A furnace comprising an interior furnace-chamber A to receive the fuel provided with outlet-openings G placed at intervals along the sides, passages H leading from the openings G to an air-chamber F and airchamber F placed above and provided with regulated openings f for the admission of air into which chamber F all the products of combustion are delivered by the passages H and into which chamber F is admitted sufficient air to promote complete secondary combustion and a combustion-chamber'E with exits e placed between the air-chamber and the structure to be heated into which chamberE all the products of combustion and the admitted air pass substantially as described.
2. In a furnace the combination with the furnace-chamberA to receive the fuel the airchamber to receive a regulated supply of admitted air and a combustion-chamber for secondary combustion, of the outlet-openings G and passages II through which all the products .of combustion are carried to the airchamber F the inlet-openin g f through which a regulated supply of air is admitted to the air-chamber the pivoted regulator-door M connected by a chainand pulley with the furnace door K which opens simultaneously therewith to prevent an inrush of air into the furnace substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WVILLIAM BROTHERS.
