APPARATUS FOR HEATING BOILERS BY GASEOUS FUEL.
SPECIFICATION forming part of Letters Patent No. 483,352, dated September 27, 1892.
Application filed April 11, 1891.
To all whom it may concern-.-
Be it known that 1, JAMES L. HASTINGS, of the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improvement in Apparatus for Heating Boilers by Gaseous Fuel, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.
Myinvention relates to the heating of steamboilers, and has for its object the rapid and economical geneiation of steam.
Particularly my invention relates to the economical use of gaseous fuel and a novel combination of water-gas generators with the boiler-furnace.
The nature of my invention will be best understood as described in connection with the drawings, in which Figure 1 is a sectional elevation taken on the line 1 2 of Fig. 2, and Fig. 2 aplan viewshowing combined batteries of boilers and gasgenerators.
A indicates the masonry surrounding the boilers; B, the boilers having fire-tubes O; D, the stack; E and J, the fire-box divided into front and rear communicating chambers, as shown, by a wall or bridge I, I indicating the passage connecting the chambers E and J.
F indicates a grate, upon which is supported a mass of fire-brick or similar material G with intercoinmunicating interstices.
H is a chamber beneath the grate corresponding with the ash-pit of an ordinary furnace, but used by me as a flue for the admission of air beneath the fire.
Beneath the rear fire-chamber J is a combustion chamber J, supported over chamber K by an arch or bridge of tire-brick or similar material K, said firebrick being perforated, built up in checker-work or in any of the well-known plans by which communication is made through a mass of refractory material interposed between communicating chambers and used for storing heat.
J is a flue or combustion-chamber communicating with the rear of chamber J and with the tuyeres C.
L L L, 850., indicate water-gas generators, which, as shown, are made up of two connected fire-chambers L and L the connection be Serial No. 388,478. (No model.)
ing formed through a dome L at their top, through which dome oil is introduced for carburett-ing the gas, M being an open-ended retort, into which the oil is allowed to fall in spray or in mass.
There is nothing in the generator shown which is new with me, and it will be understood that any of the well-known forms of water-gas-generators may be used. The generators communicate through a perforated wall N with a fine or passage 0, from the lop of which leads a conduit 0 and from the side of which leads a conduit 0, said conduit communicating with the conduit 0 Valves P and P are provided to close either of the conduits leading from the flue O at will. The conduit 0 leads through conduit 0 to a receptacle R, which, it will be noticed, is common to the whole battery of generators, and from receptacle R pipes U lead into the mass of fire-brick supported in the front fire-chambers beneath each boiler. The conduits 0 lead to a receiver Q, which, like the receiver R, is common to the Whole battery of generators, and from receiver Q conduits or passages S lead to the combustion-chambers K at the rear of each boiler.
T is an air-flue kept supplied by a blower, (not shown in the drawings,) and T T, &c., are pipes leading from conduit T through receiver Q and passages S to chamber K.
The receiver B may be of any desired size,' according as it is desired to store gas or not and is kept full of water-gas, the valves P be- 8 5 ing opened andthe Valves P closed in each receiver that is making water-gas. The receiver Q, on the other hand, is kept full of producer gas, the valves P being closed and the valves P opened, which connect with each genero ator which is making producer gasin the process of blowing up preparatory to a run of water-gas. Where a number of generators are used, it is advisable that the receptacles R and Q, should be comparatively smaller, so that the gases will pass rapidly through them to the points of combustion, losing but little heat on their way, and for the purpose of economizing heat I consider it advisable to line the conduits through which the water-gas xoo passes with fire brick, as indicated in the drawings, and to pass the air-blast pipes T through the receiver and the passages S, so that the air will be heated by the coming in contact with the producer-gas in chamber K.
I prefer in all cases to use both water and fuel gas in the Way indicated in the drawings; but it is, Ibelieve, novel and a feature of some value to supply the fire-chamber of a steamboiler furnace with gas and air introduced both in front of and behind a bridge-wall dividing the fire-chamber, as indicated, and especially to introduce the gas-supply at the rear of the fire-box first into a combustionchamber, where it. is supplied with air and ignited, and thence through perforated brickwork into the firechamber proper, situated above the combustion-chamber and forming a part or continuation of the front fire-chamber. The best results are, however, obtained by using water-gas in the front fire-chamber and producer gas in the combustion-chamber beneath the rear fire-chamber.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is 7 1. The combination of a Water-gas generator, a receptacle for water-gas, and a receptacle for producer-gas communicating with the take-off of the generator, valves for closing the connection to either receptacle at Will,
a boiler, a tire box extending beneath the boiler and separated into front and rear communicating chambers by a bridge, connections from the Water-gas receiver to the front chamber, and connections from the producergas to the rear chamber.
2. The combination of a water-gas generator, a receptacle for water-gas, and a receptacle for producer-gas communicating with the take-off of the generator, Valves for closing the connection to either receptacle at will, a boiler, a fire -box extending beneath the boiler and separated into front and rear communicating chambers by a bridge, a combustion-chamber situated beneath the rear firebox chamber and communicating therewith through checkered fire-brick or its equiva lent, connections from the Water-gas receiver to the front chamber, and connections from the producer-gas receiver to the combustionchamber.
3. The combination of a series of water-gas generators, a common watergas receptacle and a common producergas receptacle, conduits leading from each generator to each receptacle, Valves in said conduits,whereby they can be closed at will, one or more boilers, fireboxes extending beneath said boilers and divided into front and rear communicating chambers by a bridge, conduits leadingfrom the water-gas receptacle to the front fire-chambers, and conduits leading from the producergas receptacle to the rear fire-chamber.
