PREVENTING SMOKE IN FURNACES.
SPECIFICATION forming part of Letters Patent blo. 727,729, dated May 12, 1903. Application filed August 11, 1902. Serial No. 119,243- (Ne model.)
To all whom it may concern.-
Be it known that we, JAMES WILSON, engineer, residing at Ferrier. Works, North street, and JOHN STENHOUSE KEMP-WELoH, engineer, residing at Bell Lane Iron Works, Wandsworth, in the county of Surrey, England, subjects of the King of Great Britain,
have invented a certain new and useful Improvement in Preventing Smoke in Furnaces, of which the following is a specification.
The object of this invention is the prevention of smoke, especially when fuel is being put upon the fire. For this purpose the bridge of the furnace is hollow and contains a regenerator of fire-brick or the like. When the fire is being stoked, air from the ash-pit is passed through this regenerator and mingling with the smoke consumes it. When which by its combustion heats the regenerator.
- Figures 1 and 2 are longitudinal vertical and horizontal sections of a boiler having two furnaces constructed according to this invention. The upper part of Fig. 2 shows the fire-- bars in place, and in the lower part they are removed. Fig. 3 is a half-section on the line 3 3, Fig. 1, and a half end elevation with the door removed.
or represents the fire-bars, and a, the ash-pit.
b is the hollow bridge, filled with open-work brick c, forming a regenerator.
d is a gas-main, and 6 represents branch pipes leading from it to the regenerator.
f represents cocks on the pipes e.
g is a damper admitting air to the regenerator, and h is a chain by which it is operated.
The operation of the apparatus is as follows: When the fire is burning clear in any one of the furnaces, its gas-cock f is opened and its damper g is partially closed, so as only to ad- 'mit sufiicient air to burn the gas entering the regenerator through the cook. The combus-- tion of the gas in the regenerator renders it intensely hot. When fuel is put on the fire,
the cock f is closed and the damper g is fully opened, thereby admitting a large quantity of air, which, rising up through the regenerator, becomes intensely hot, so that when it issues into the furnace at the bridge and comes into contact with the smoke it ignites and completely burns it. The passage of the air through the regenerator gradually cools it,and when the fire has burned clear it is again heated, as above described.
The term regenerator is used in this specification in its ordinary sensethat is to say, a heat-reservoir, such as a mass of loose brickwork adapted to be alternately heated by combustion within it and cooled by passing air throughit. The term is not intended toinclude externally-heated structures.
We 'claim 1. In a furnace the combination of gratebars, an ash-pit' below the grate-bars, a hollow bridge having a regenerator within it over which'the products of combustion pass, means for supplying gas to heat the interipr of the regenerator, and means for passing air through the regenerator and into the products of combustion above the bridge when the gas is cut off.
. ,2. In a furnace, the combination of gratebars, an ash-pit below the grate-bars, a hollow bridge having aregenerator within it over which the products of combustion pass, a gaspipe leading to the regenerator and supplying for supplying gas to the interior ofthe regenerator to heat it, and for cutting ofi the supply of gas thereto, and means for passing air through the regenerator and for cutting as said air-su pply, substantially as described.
