Description

In the proposed rotary furnace with an inclined axis and with a ribbed fireproof lining inside, the furnace has the appearance of a conical drum with several openings with gratings in the di- rect furnace for release, and the ribs of the inner lining have a spiral shape.

In FIG. 1 draws a longitudinal section of the furnace; FIG. 2-cut drum section.

The fuel from Benker 1 is supplied by a screw 2 through a hollow trunnion 3, mounted on the front Bottom 4 of the rotary chamber drum 5, into the chamber 6, which has a cone shape and is installed with an inclination / upward; the open end of the drum enters the heat pipe of the boiler,

The drum is made of sheet iron 7 n inside lined with brick 8 (Fig. 2) with longitudinal ribs 9 directed along the generatrix or along the helical lines. The conical shape, sloping downward and into the ribs are made with the aim of shifting the fuel moved by the moving gases from the sneg to the boiler, in the opposite direction from the boiler to the bottom of the drum and thereby delay the unburned

I fuel in the furnace as much time as will be necessary for its complete combustion. Along the circumference at the bottom of the sde. There are several holes with grates 10 for removing slag from the combustion chamber. The drum rests on the rollers 8 and rotates from the drive on. in the drawing, not shown, but outside, for the purpose of cooling, is washed with air.

The subject of the patent.

1, Rotary hearth with a sloping axis and with a ribbed refractory lining inside, characterized in that it is made in the form of a conical drum 5 with a large base 4 at the fuel injection point and with gratings 10 near this base for slag production, which device aims reach the unburned fuel particles back down to the front bottom to catch it again with an air stream.

2.In characterized in c. 1 firebox application inside the drum ribs 9 spiral shape. to the patent A. A. Shershnevna and.; M1 17547 8. V. Prokhorov
