Description

FIELD OF THE INVENTION The present invention relates to fiery heating furnaces with gently bending arch with a ledge at the end. In order to achieve a quick and uniform heating of the material, as well as to improve the efficiency of the furnace, the front end wall of the furnace is equipped with a visor located above the loading window that guides gases from the roof into the channels located in the hearth of the furnace on both sides of the loading window. At the loading windows in the furnace, exhaust channels are arranged connecting the working chamber with the chimney going under the furnace. The proposed stove can operate on both oil and coal.

In FIG. 1 shows a longitudinal section of the oil furnace; FIG. 2 is a section through AB of FIG. one; FIG. 3-section on GD, FIG. one; FIG. 4-longitudinal section of the coal-fired furnace; FIG. 5-section on .g. four; FIG. 6 is a section along AB of FIG. four.

Located on the foundation 1, a furnace with a gently bending arch 5 is divided by threshold 9 into

a combustion chamber 6 with an opening 8 for the nozzle (fig. 1 - 3) and to the working chamber 2, equipped with loading windows 10 and 17, 17 ... Above the loading window there is a peak 11 that serves to direct gases from the roof to the channels 13, Available in the hearth 14 of the furnace on both sides of the boot window 10. In addition to the channels 13 in the hearth, the boot windows 10 and 17, 17 ... have channels 12 and 22 that connect the working chamber 2 with the chimney 16 located under the hearth 14 and communicate with chamber 15, designed to otzhig products and loaded through the window 23, which also serves to clean the chimney ov Channels 12 and 22 are designed to draw in cold air through windows 10 and 17, 17 ... when the furnace is charged, which is intended to achieve a more uniform heating. In addition, the presence of these channels should prevent the ingress of smoke to the outside during careless kindling.

FIG. 4 - 6 depicts a stove designed for working on coal, with the same characters for the same parts as

and in FIG. I - 3. The furnace is equipped with a combustion chamber 6 with grate 4 and a loading door 3. In order to improve the combustion, air is blown into the aspirator 5 through the pipe 19 heated in the channel 18 of the furnace.

In both of the above-described pipes, hot gases from the workplace run through channels — 13, 12, into the chimney 16 and, through it, are heated from below under 14, contributing to a more uniform heating of the material. In this case, a part of the heat of gases is used in the chamber 15 for annealing the products.

 of the patent.

A flame kiln furnace on oil or coal heating with a gently bending arch with a ledge at the end, characterized by the fact that the front end wall of the furnace is equipped with a visor 11 (Fig. 1-6) located above the loading window 10 and serves to direct gases from the arch channels 13, which are located in the hearth of the furnace on both sides of the said window 10, and at the boot windows in the hearth of the furnace there are exhaust channels 12 and 22 connecting the working chamber of the furnace with the chimney 16 going under the furnace hearth.
