' HEAT ABSOBBI'NG AND RADIATING, APPARATUS.

Application filed January 22, 1924. Serial No. 687,882.

To all whom it may concern: I

Be it known that I, NICHOLAS J. ZUZULIN, a citizen of the United States, residing at Minot, in the county of Ward and State of North Dakota, have invented certain new and useful Improvements in Heat Absorbing and Radiating Apparatus, of which the following is a specification.

My invention relates to furnaces, and has particular reference to the fire box construe provide a fire box for a furnace, such as a steam or hot water boiler, having means for storing heat in the upper portion of the combustion. chamber, so that the combustible gases escaping from the fuel, such as lignite, are properly burned. I

A further object of the invention is toprovide means whereby thecold air rushing into the fire box or combustion chamber,

upon the opening of the door for theintroduction of fuel, is heated prior to passing to the tubes of the boiler, whereby they are not reduced in temperature, as frequently ocours with the ordinary boiler.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in. which like numerals are employed to designate like parts throughout the same.

Figure 1 is a central vertical longitudinal section through a boiler embodying my invention.

Figure 2 is a transverse section taken on line 2-2 of Figure 1, and,

Figure 3 is a horizontal section taken on line 3--3 of Figure 2.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 desig nates combustion chamber of a boiler, having the usual crown sheet 6. Arranged beneath this combustion chamber is the fire box Y, having a grate 8, beneath which is the ash pit, as shown. The combustion chamber 5 discharges into the rear ends of fines or tubes 10, held within a shell 11, for holding the water, as is well known in a hot water furnace. The invention is also applicable to a steam boiler construction. The numeral 12 designates a door for the combustion chamber and fire box, and 13 is a door for the ash pit.

The invention resides particularly in the provision of heat absorbing and distributing means, arranged within the combustion chamber 5. Such means embodies a plurality of arches or. inverted U-shaped ele ments 1 1, 15, 16, 17, 18 and 19. These elements are substantially identical in construc tion, but vary in height, and somewhat in shape. Each element embodies an inverted U-shaped rod 20, the lower end of which is embedded in the side walls 21 of the combustion chamber. Arranged upon each of these inverted U-shaped rods are a plurality of heat absorbing and releasing memhers or blocks 21, such as fire bricks. It is preferred that these fire bricks be rough and porous in order that they will more readily absorb the heat and radiate the same. The fire bricks 21 have central openings formed therein, for the reception of the rod 20. These. fire bricks are suitably spaced upon the U-shaped rod by asbestos spacing collars 22, asshown. The fire bricks are held upon the rod, against displacement, by frictional engagement therewith, or by any other suitable means. In the arched portion of the element produced by the fire brick, the lower edges of the fire brick; preferably contact. As clearly shown in Figure 1, the element 18 extends above the element 19, while the element 1.7 is below the element 18 but above the element 19. The element 1.6 extends above the element 17 while the element 15 is below the element 16 but extends above the element 17. The element 14 extends above the element 15 and the element 16. A staggered stepped relation is thus produced at the tops of these elements, with a combustion chamber occurring above the adjacent intermediate element and between the ends of the two elements upon opposite sides thereof. Attention is called to the fact that the elements 14;. 15, 16, 17, 18 and 19 are spaced, providing vertical passages which lead into the combustion chambers or pockets 2 1, as shown.

In view of the foregoing description, it will be seen that coal is ignited in the fire box 7. and when lignite is used, the com hustible gases pass from the fire box 7 upwardly through the passages 23, and enter the combustion box 24-. The heat stored in the elements or arches 14 causes these combustible gases to be properly ignited. Then the door 12 is opened for the introduction of fuel into the fire box, cold air rushes fit) , means for storing heat, and radiatin same at the proper time, thereby retaining into the fire box, but this cold air passing upwardly'between and about the heat retaining and radiating elements, is properly heated before it reaches the tubes 10 whereby these tubes are not reduced in temperature. The arches or elements serve asha t e the temperature of the furnace substantially even, in addition to effecting the combustion of the gases, escaping from the fuel.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims. a

Having thus described my invention, what I claim is:

1. A furnace including a combustion chamber and a fire box at the bottom thereof, and a plurality of upstanding arches arranged within the combustion chamber and longitudinally, spaced therein providing upwardy discharging passages for the combustible gases, the tops of the arches being arranged in staggered relation affording combustion pockets in communication with said passages, said combustion pockets being arranged at different elevations, each arch embodying an inverted U-shaped rod, and a plurality of earthen blocks strung upon the arch and held thereon in spaced relation.

2. A furnace including a combustion chamber and a fire box at the bottom thereof, and a plurality of upstandin arches arranged within the combustion ciamber and longitudinally spaced therein providing upwardy discharging passages for the combustible gases, the tops of the arches being arranged in staggered relation affording combustion pockets in communication with such passages, said combustion pockets being arranged at different elevations, which elevations are lowered toward the discharge end of the combustion chamber.

3. A furnace including a combustion chamber and a fire box at the bottom thereof, and a plurality of upstandin arches arranged within the combustion c amber and longitudinally spaced therein providing u wardly discharging passages for combustible gases, the tops of the arches being arranged in staggered relation affording combustion pockets in communication with said passages, said combustion pockets being arranged at different elevations which elevations are lowered toward the dischar end of the combustion chamber, each arc embodying an inverted U-shaped rod, and a plurality of earthen blocks strung upon the rod and held thereon in spaced relation.

In testimony whereof I afiix my signature.

NICHOLAS J. ZUZULIN.
