Description

Heating furnaces are known, consisting of a combustion chamber and a heating chamber located around it; in which the preheating of liquid fuel and air are applied.

In order to cool the outer yladka of such furnaces near the filling windows, it is suggested that in these places, the outside of the furnace should be equipped with boxes or coils with circulating cold water in them.

In FIG. 1 depicts a vertical section of the furnace, sn9.bzhennoy cooling boxes; FIG. 2 is an external view of the ate of the furnace from the side of the nozzle and FIG. 3-exterior view of the stove, equipped. cooling coils.

On the outside, brick masonry b (Fig. 1) of the furnace is covered with a iron casing a, and inside the furnace there is a combustion chamber, limited by the tab c. Filling windows d (Figs. 1-3) serve for laying the preforms in the furnace. Air required for combustion is pumped into the furnace by the h pipe (Fig. 2.3), heated on its way as the pipe h passes under the hood with the heat of the gases leaving the furnace, and enters the nozzle J, where it is mixed with oil supplied through

G. Well pipe I, winding-in tse.1 x heating oil-chimney, t. The mixture burns in the combustion chamber (Fig. 1) and the combustion products enter the working chamber and the channels r, where the workpiece placed there is heated and through the channels, in the outer walls of the furnace, go to the chimney t. The outer sides of the furnace at the filling windows are cooled with water coming into the pipe / box e (Fig. 1, 2) by turning in it (Fig. 1) against the filling windows or into the coil e (Fig. 3), whose branches are placed between the vertical Rows of bookmark windows. From the cooler, water is discharged through pipe d (Fig. 2, 3),

The subject of the natent.

Adaptation to heating furnaces for cooling the outer sides of the furnace at the filling windows, characterized by the fact that the external wall from the external side at the filling windows is equipped with water cooled: the box e (Fig. 1.2) with openings against the filling windows, or a coil e 3), the branches of which are located between the specified tabs.
