STERLING ELLIOTT, OF BOSTON, MASSACHUSETTS.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 755,286, dated March 22, 1904. Application filed August 19, 19Q2. Renewed September 23,1908- Serial No. 174,379. (No model.)
end I construct and arrange the parts as fully set forth hereinafter and as illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of suflicient of a boiler and burner to illustrate my improvement. Fig. 2 is a plan on the line2 2, Fig. 1.
A represents a boiler or generator, below which is a vapor-burner B of any suitable character having the usual air passages 1, (shown in dotted lines,) through which air passes to a combustion-chamber. To heat this air, and thereby facilitate combustion, I arrange below the burner a heater C, with which the air must pass in contact, acting as a radiator to heat the same before it passes to the burner. This heater may be of any suitable character, but preferably consists of a'coil of pipe 2, communicating with the exhaust-pipe 3, extending from the valve-chest S of the engine, whereby the coil is heated by the exhaust-steam. In order to economize heat, I- make use of the heater-coil C as a means of heating the feed-water, and to this end I extend concentric with the pipe of the coil a 1 smaller pipe 5, which communicates with a pipe 6, connected withthe feed-pump P, preferably so that the feed-water flows in a direction opposite to that of the exhaust-steam in the outer pipe. These parts may be constructed 'and arranged in any suitable manner, and the coil C or other arrangement of pipe may be of any suitable arrangement, either with curved or straight sections, and there may be a plurality of coils one above the' other.
Without limiting myself to the precise construction and arrangement of parts shown and described, I claim 1. The combination with a boiler, and vapor-burner below the same, of a heater-pipe arranged below the burner to heat the air direct the feed-water in a direction the reverse of that in which the steam flows through the outer pipe, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
. STERLING ELLIOTT.
