HERBERT J. LONG, OF CLEVELAND, OHIO.
HEATER FOR HOT-WATER SYSTEMS.
SPECIFICATION forming part of Letters Patent No. 762,541, dated J une 14, 1904.
Application filed May 21, 1902. Serial No. 108,314. (No model.)
To all whom it may concern:
Be it known that I, HERBERT J. Lone, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Heaters for Hot-VVater Systems, of which the following is a specification.
This invention relates to heating apparatus employed in connection with hot-water systems, and is especially adapted to circulating systems used for heating buildings. Its object is to provide an economical, self-contained, and efficient heater for circulating hotwater systems in which the circulating water may be heated by steam tubes and surfaces instead of being brought into contact with surfaces heated directly by the fire in the usual way, thereby combining in an isolated heating plant the advantages resulting both from heating rooms by radiation from hot water and from generating heat in the form of steam. Steam can be raised in a boiler of proper construction with a smaller consumption of fuel than is required to produce the absorption of the same amount of heat by a large body of water confined in drums, tubes, &c., and therefore my apparatus by accomplishing first the production of steam from the direct heat of the fire and then providing for the ready absorption of the heat from the steam by the large body of water in the circulating system effects a considerable saving in the quantity of fuel required. The danger and disadvantages resulting from the incrustation of water-tubes and the choking of firetubes, as usually employed in heaters for water systems, are also eliminated. Minor objects will become apparent from the description.
To these ends my present invention consists in the arrangements and combinations hereinafter described and claimed, an embodiment thereof being illustrated in the accompanying drawings, in which- Figure I is a sectional elevation of the heater. Fig. II is a section taken on line II II of Fig. I. Fig. III is a section on line III III of Fig. I. Fig. IV is a sectional elevation of the heater arranged for using gaseous fue The reference-letter (4 indicates a cylindrical shell having a top head at 6, between which and a partition 0 is formed a compartment (Z, in which the circulating water is heated. A flow-pipe e connects the heating or other water system with the compartment cl through an aperture in the top head, and a return-water pipe from said system enters the side of said compartment at f. The shell ranged for burning either solid or gaseous fuel. In Fig. I, which illustrates a coal-burning heater, the shell a is supported upon a suitable ash-pit j, and a cylindrical furnace Z; is secured inside thereof. Another shell Z, opening at its upper end into the steam-drum g, surrounds the furnace is, thus forming an annular water-leg between 7s and Z and an annular space between Z and the outer shell (4. The gases of combustion pass out of the furnace through the flue on into the upper rear part of the outer annular space, from whence they are deflected around to the front by the plate a and descend through apertures 0 in said plate to the lower part of said space, from whence they are drawn off at the rear by the smoke-pipe p.
In arranging the device for generating steam with gaseous fuel I prefer to construct the lower part as shown in Fig. IV, in which the shell (0 is provided with a lower head (1 and supported upon stanchions, such as r. A suitable gas-burner s is set thereunder, through which passes a water-pipe formed into a coil t above said burner, both burner and coil being inclosed in a suitable casing. The upper end of said coil is connected with the steam-drum g, and the lower end is supplied with water by pipes a, which are also connected with the steam-drum, all as plainly shown in Fig. IV.
Various modifications may be made in the arrangement of the lower or fuel -burning part of the apparatus provided efficient and economical means are employed for raising steam in the drum g and provided the principles of construction set forth, respectively, in the following claim are employed.
I therefore particularly point out and distinctly claim as my invention In a heater for hot-water systems, the combination of a boiler-shell, a partition near its upper portion dividing said shell into a watercompartment above said partition and a steamspaee below said partition, a plurality of vertical tubes opening into said steam-space and
