SU20106A1 - A device for obtaining proper pressure distribution in the heating chambers of corridor furnaces - Google Patents

Description

A negative factor in the operation of all corridor furnaces of the ordinary type is the fact that the heating chamber at the floor pressure is less than in the cooling chamber. The difference in the pressure at the bottom of the heating chamber and the cooling chamber causes the relatively cold air from entering the heating chamber. cooling chambers, which entails a large temperature difference, a large excess of air in the working gases, which affects both metal waste and fuel consumption.

By means of the proposed device, it is necessary to eliminate the above-described drawbacks of the furnace operation, for which it is necessary to create a higher pressure on the hearth of the heating Kaiviepbi than on the bottom of the cooling chamber, which is the basis for the correct design of the fire chamber of the corridor furnace. This condition is achieved by using a design based on the hydraulic theory of flame motion in furnaces.

In FIG. 1 shows a device for a corridor furnace with a furnace for oil in a vertical longitudinal section; FIG. 2-in vertical transverse

cut; FIG. 3 is the same, in horizontal section; FIG. 4 — device to the corridor furnace for generating gas in a vertical longitudinal section; FIG. 5 something the same, in a vertical cross section.

The device consists in creating a moving head by means of a WWES siphon, one knee of which, filled with warm gases (300-600), is connected by a hole in the hearth to cooling chamber B, and the other knee of ZZH is connected by an opening in the hearth to heating chamber L, which serves to heat items B, and filled with hot gases (1200-1400 °).

The difference in weight between the pillars of gases that fill both knees creates a driving head that goes partly to create velocities along the path of the gases in the siphon and which serves to obtain the required excess pressure at the bottom of the heating chamber over the pressure in the cooling chamber.

The high temperature in the knee of the ZZh of the siphon is achieved in such a way that the throat reaction starts at the lower end of the Z of the knee of the ZZH. Conclusion hot

gases from the knee ZZh of the siphon into the chamber. AH heating A is placed on the hearth and can be divided into several jets, as shown in FIG. one..

The subject of the patent.

A device for obtaining the correct distribution of pressure in the heating chambers of corridor furnaces, characterizing

The use of the SZPON SZPHON, one knee JZ of which, filled with warm gases, is connected by a hearth hole to the cooling chamber -B, and the other ZZH knee is connected by a hole in the hearth to the heating chamber A and is filled with hot gases obtained by burning the fuel so that the reaction Burning began at the lower end of the knee ZZ siphon. ..
