Description

In the proposed device for heating the furnace flowing through the firebox through channels in the air masonry, channels formed under the firebox are used, and air enters the open door, bends around the partition separating the channels and falls under the grate, which is offset to the side so that ash pit.

In FIG. G depicts the external appearance of the device; FIG. 2 is a vertical section according to 2-2 of FIG. four; FIG. 3 through 3-3 of FIG. four; FIG. 4 is a horizontal section through 4-4 of FIG. 3; FIG. 5 the same in 5-5 of FIG. 3

Under the firebox, the channels A formed by dividing the cavity under them by a partition not reaching the rear wall, are washed by hot gases leaving the firebox. One of the openings of the channels a is inserted a door about, serving only for cleaning the grate and blowing ash from the ashes, and the other is inserted into the door serving for the inflow of outside air under the grate located only above one of the channels a,

HELL

Before the furnace is kindled, the door b is opened and the grate is cleaned under the firebox r above it, then, when the fuel has burst, the door b is closed hermetically and the door B is opened, through which the flow of air entering the furnace is already heated, which increases the efficiency of the furnace. At the end of the firebox, the door is also closed.

S The subject invention.

The device in the furnaces for heating the air flowing into the firebox with the use for this purpose in laying of channels that are different in that channels a and a are formed under the fire box by dividing the cavity under the BAT by a longitudinal wall that does not reach the rear wall and has separate doors c, and the grate in the mold is displaced to the side so that it is located only over one of the channels that serves as an ash pan for it.
