HANNA I-IAAS, or new YORK, N. Y.
FURNACE.
To all whom it may concern:
Be it known that I, HANNA HAAS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Furnace, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved furnace, more especially designed for burning asphalt and like materials as the fuel and arranged to insure complete combustion and to produce a high heat, to be utilized for generating steam and for other purposes.
In order to accomplish the desired result, use is made of a tray extending within a combustion chamber and adapted to receive the semi-fluid fuel, to be acted on by a blast or a jet, to atomize the fuel, and to form a mixture to be burned in the said combustion chamber.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of thisspecification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a cross section of the furnace; Fig. 2 is a reduced longitudinal section of the same; and Fig. 3 is a reduced sectional plan view of the same, on the line 3-3 of Fig. 1.
In one end of a suitably constructed brick work- A is arranged a combustion chamber B, provided in its bottom with a grate C, below which is arranged an ash pit I), access being had to the combustion chamber B and the ash pit D by doors E, E, arranged on the front end of the brick work A, as plainly indicated in Figs. 2 and 3.
Within the combustion chamber B and ranging lengthwise on the sides thereof are trays F, extending above the grate C and supported on ledges A forming part of the sides of the brick work A. Each of the trays F is provided with spaced inlets F, extending through the sides of the brick work A to the outside thereof, and the outer ends of the inlets F are normally closed by doors F which when open permit of introducing the asphalt or other similar fuel into the inlets F, to pass down the inclined bottoms F of the trays F, to then flow into pockets F formed in the trays between adjacent inlets F, as will be readily understood by reference to the drawings. The
Specification of Letters Patent.
Application filed March 22, 1910.

Serial No. 550,840.
asphalt or other similar semi-fluid fuel passing into the pockets F is subjected therein Y i to the action of blasts of air, steam or other fluids, introduced through blast pipes G, extending in the sides of the brick work A in a downward and inward direction, as plainly shown in Fig. l. The outer ends of the blast pipes G are connected with pipes H, leading to a suitable source of compressed air, steam or other fluid, used for atomizing the fuel in the pockets F', and for blowing the same into the combustion chamber B, to form an inflammable mixture to be burned within the said combustion chamber B.
Longitudinally -extending air admission channels I are arranged in the ledges A, and are connected by vertical channels I, with transverse openings I extending under the trays F and opening into the combustion chamber B, at points between the grate C and the inner ends of the trays F (see Figs. 1 and 2). The openings I have outward extensions I leading to the outer face of the sides of the brick work A, and openings I* lead from the channels I into the ash pit D, and when the furnace is in use air can readily pass into the combustion chamber B and the ash pit D by way of the channels I, I and the openings I I and I, so as to insure complete combustion of the burning mixture in the combustion chamber B. The outer ends of the channels I and the extensions I may be con nected with a blower, to force the air into the combustion chamber B and ash pit D. Ordinarily, however, a natural flow of air produced by the draft in the furnace is suflicient for producing complete combustion of the vaporized mixture in the combustion chamber.
From the combustion chamber B extends a duct or channel J leading to a boiler or other apparatus to be heated, and the said duct or tube J is preferably filled with staggered or checker firebrick, to retain the products of combustion in the fire box until complete combustion has taken place.
On the front end of the brick work A are arranged holes K, leading to the combustion chamber B above the trays F (see Figs. 2
and 3), to permit of observing the burning the blast coming through the pipes G, to insure the quick and thorough atomizing of the fuel, with a view to forming a highly inflammable mixture, which is readily burned in the combustion chamber B. By the influx of air through the openings 1 a complete combustion of the burning mixture takes place, and any liquid fuel that flows over the inner edges of the trays F readily drops down onto the loose fire brick held on the grate C, and as the said fire brick is heated and air comes up from the ash pit D, the said fuel is readily vaporized and burned in the combustion chamber B.- The heat developed in the combustion chamber B finally passes through the duct J to a boiler or other apparatus to be heated. Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A furnace for burning semi-fluid fuels, comprising a combustion chamber, a tray in the said combustion chamber, charging means for charging the said tray with semiliquid fuel, means for directing a blast on the said semi-liquid fuel to atomize the same within the combustion chamber, and air admission channels in the wall of the furnace and discharging into the combustion chamber underneath the said tray.
2. A furnace for burning semi -liquid fuels, comprising a combustion chamber, op-
positely-disposed trays within the said combustion chamber and ranging lengthwise on the sides of the furnace, the said furnace being provided with normally closed inlets extending through the sides thereof for charging the trays with the semi-fluid fuel, pipes in the sides of the furnace for directing a blast into the fuel in each tray in a downward and inward direction to atomize the fuel and to form a mixture passing into the combustion chamber to be burned therein.
3. A furnace for burning semi -liquid fuels, comprising a combustion chamber having a grate at its bottom, an ash pit below the grate, trays ranging lengthwise on the sides of the combustion chamber, means for delivering the fuel through the sides of the furnace to the said trays, and pipes in the sides of the furnace and inclined downwardly and inwardly to discharge blasts onto the surface of the fuel in the trays to atomize the fuel and form a mixture to be burned in the said combustion chamber.
4. A furnace for burning semi-fluid fuels, comprising a combustion chamber having a grate at its bottom, an ash pit below the said grate, doors leading to the said combustion 'chamber and ash pit, trays ranging lengthwise 011 the sides of the furnace within the said combustion chamber and having pockets for the semi-fluid fuel to flow in, blast pipes arranged in the sides of thefurnace and extending downwardly and inwardly in the direction of the said pockets to force blasts onto the fuel in the pockets, and air admission channels in the sides ofthe furnace and discharging into the combustion 1 chamber underneath the said trays.
