OOFRAN I. HALL, OF SAN FRANCISCO, CALIFORNIA.
STEAM- BOILER FURNACE.
SPECIFICATION forming part of Letters Patent No. 244,051, dated July 12, 1881.
Application filed May 24, 1880. (No model.)
To all whom it may concern Be it known that I, OOFRAN I. HALL, of San Francisco, California, have invented a new and useful Improvement relating to Furnaces for Steam-Boilers, which improvement is more particularly applicable to such furnaces as are supplied with straw for fuel, of which the following is a specification.
The object of my invention is to assist in the combustion of the straw or other fuel in furnaces, by supplying a continuous series of fine air-currents fromablast-pipeon both sides of the furnace, giving a direction to the said air-currents crosswise of the furnace, or approximately so, and at a line close to the grates, but above them, so that the fuel may be less agitated than would be the case if the blast was introduced in a concentrated form below the grates and directed upward.
In Figure 1 of the accompanying drawings I show a side view of a boiler of the ordinary locomotive-firebox type (such as is ordinarily used on portable thrashing-machines) with my apparatus connected therewith. Fig. 2 is a plan of same.
In these two figures, A represents the boiler-cylinder; B, the fire-box; G, the steam-cylinder of the engine; D, the crank-shaft; E, the fan-blower, attached to side of boiler and run by a belt from a large pulley, D, secured on end of engine crank-shaft D.
F is the leading-pipefromfan-blower, branching into the furnace in any manner suitable to the construction of the furnace; and G G are air-distributing pipes placed just above the grates H. These distributing-pipes are perforated with a series of small holes in such a manner as that the issuing air-currents will be directed across the furnace from side to side with considerable force. For this reason the holes should be no greater in number and aggregate area than will correspond with the area of the leading-pipe F. In fact it would be better to make the leading-pipe F of a little greater area than would be the combined area of all the distributing holes.
I is an arch-plate or deflector commonly used in furnaces. It is supported upon the pipes J, which are connected between the crown-sheet of the furnace and the tube-sheet of the boiler, below the tubes or flues.
K is the door of the furnace through which the straw fuel is introduced. The straw-feeding apparatus usually attached to these furnaces I do not show in the drawings, as it does not form a part of my invention.
The distributing-pipes on each side of the furnace should be as narrow as possible through their horizontal axis, but may be broader vertically. This is because most furnaces require all the room that can be obtained for gratesurface, and two large pipes on each side would take up more room than could ordinarily be spared. The pipes therefore may be flattened out, so as to present an oval cross-section instead of a perfectly round one.
It will be desirable in most.cases to provide for the distributing pipes being withdrawn from the furnace during the period that the fire is being used to make steam, and before the steam acquires sufficient pressure to operate the engine, and through it the blower, otherwise a hot fire might burn out the pipes G G when not protected by cold air passing through them.
Of courselthe pipes G G may be withdrawn in several ways; but I propose as the simplest to make the joint at a loose enough to permit the pipe and branches from that point forward to be turned down and out of the fire.
The branch pipes G G may be supported firmly in place when operating by resting their ends upon the back grate-bar bearer, if there is one used, or upon a stud or pin, as at b, Fig. 1, fastened in any convenient manner in sides of the furnace.
When the air-blast is strong enough to agitate the fuel and the draft draws it upward the arch-plate I will act to stop the rising parcles of fuel from going directly into the flues until they are thoroughly consumed, otherwise much of the light straw fuel, which is easily raised by a strong draft, such as a blast from a fan-blower would give, would be wasted by passing out of the furnace into the Chilllopen spaces at the sides of the grates when IO ney, where it would, if not arrested byasparksaid pipes are not operating, all constructed catcher beingafire, do great damage. and arranged substantially as shown, and for What I claim as my invention, and desire to the purpose described. 5 secure by Letters Patent, is as follows:
In a locomotive-boiler, the air-pipes G G, OOFRAN HALL connected with the leading-pipe F by a swivlVitnesses: el-joint, a, on said leading-pipe, to permit the GEO. PARDY, pipes G G being swung clear of the fire through L. H REDFIELD.
