2 Claims.

This invention relates to heating devices such as boilers.

An object of my present invention is the provision of a heating device which is more economical of fuel and therefore more efficient than heating devices of a similar type now on the market.

Other objects will be appreciated by those skilled in the art on reading the following speciiication.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. l is a front elevation of a boiler embodying my invention, the View being partly broken away and partly in section; and

Fig. 2 is a horizontal. section taken on line 22 of Fig. 1, looking in the direction of the arrows.

Referring to the drawing for a more detailed description thereof, the numeral 3 indicates a boiler comprising a hollow base 5, a body 6 having a water compartment 7 and an inner wall 8. An annular wall 9 of refractory material faces the inner wall 8 and extends from the base 5 upwardly. Within the annular wall 9 of refractory material are disposed walls 10 defining a chamber 11. The walls 10 are formed from sections as shown in Fig. 2, the sections being bolted together as indicated by the numerals 12. Adjacent the bottom of the walls 10 the same are provided with apertures 15 to admit air into the chamber 11. The top wall 10 is provided with an aperture 16 to function as an air outlet. Above the air outlet 16 an air deflecting plate 1'7 rests on an annular perforate supporting member 18 which is fastened to the upper surface of the top wall 10. The deflecting plate 17 is adapted to deflect the air issuing from the outlet 16 to points adjacent the upper surface of the refractory material 9, in order to provide for a complete combustion of the fuel.

Passing through the base 5 of the boiler is a pipe 19 including a valve 20. The pipe 19 is adapted to carry liquid or gaseous fuel to burners 21 which are directed towards the wall of the water compartment '7. The contents of said compartment are thus heated. Since the wall of refractory material is close to the wall of the water compartment, a narrow annular space is be seen that the heat isconcentrated in a region adjacent the water compartment so that a great percentage of the heat will pass to the water in said compartment and not escape through the flue 25 of the boiler, which happens in boilers as heretofore constructed.

ihe air entering the chamber 11 through the perforations 15 will-be subjected to heat from the walls of said chamber derived from the incandescent refractory material and this air after heating, passes out through the perforations 18 and is directed by the deflecting plate onto the walls of the water compartment for the absorption of the heat by the latter.

What is claimed as new is:

1. In combination with a furnace having an annular water compartment and a base below said compartment, a chambered member mounted in the base and extending above the lower edge of the water compartment and having an exterior wall of refractory material close to but spaced from the wall of the water compartment to provide an annular space therebetween, and a series of burners disposed in the base in surrounding relation to the chambered member and provided with an annular series of jets directed toward the wall of the water compartment, the chambered member having air inlets at its bottom and air outlets at the top.

2. In combination with a furnace having an annular water compartment and a base below said compartment, a chambered member mounted in the base and extending above the lower edge of the water compartment and having an exterior wall of refractory material close to but spaced from the wall of the water compartment to provide an annular space therebetween, and a series of burners disposed in the base in surrounding relation to the chambered member and provided with an annular series of jets directed toward the wall of the water compartment, the chambered member having air inlets at its bottom and air outlets at the top and a deflector plate above and spaced from the chambered member to direct the air passing through the outlet perforations toward the wall of the water compartment.
