IMPROVEMENT IN DEVICES FOR HEATING AIR FOR FURNACES.
Specification forming part of Letters Patent No. 178,977, dated J une 20, 187 6; application filed May 9, 1876. F
new and Improved- Boiler-Furnace, of which the following is a specification:
The object of the invention is to utilize some of the waste heat of a' boiler-furnace for heating the air supplied to the furnace for the support of combustion. As applied to a locomotive-boiler, the smoke passes through the boiler-flues to the smoke-box, as usual, thence back in a casing covering and surrounding the upper part of the boiler, which tubes terminate in a breeching, from which the smoke escapes through vertical tubes, which form the smoke-pipe, and are surrounded by a easing, down which the air for feeding the furnace passes to the casing on the boiler containing the smoke-pipes, and to a jacket at the rear, from which it passes along under the boiler to the ash-pit.
In the accompanying drawing, Figure 1 is a longitudinal sectional elevation of a locomofive-boiler constructed according to my invention, the section being taken on the line y 3 of Fig. 2. Fig. 2 is a transverse section taken on line a:
In the drawing, A represents the furnace; B, the tubes passing through the boiler to the smoke-box U; D, tubes extending from the smoke-box through the casings E, covering and surrounding the upper part of the boiler, to the breechin g, from whichit escapes through the tubes G, forming the smoke-pipe, and being surrounded by the casing H, into the upper end of which the air enters, through the hood I, at J, passing down into casings E E", and along to jacket K, and to easing L at the bottom, from which it enters the ash-pit M, to feed the fire with hot air, the heat being obtained from that which is at present Wasted, thus effecting a considerable economy, and
the contrivance affords a hot jacket for the boiler, which is another source'of economy. 0 represents the nozzles for discharging the exhaust-steam into tubes G, and N the exhaustshown and described.
