SU94050A1 - Device to heated cupola blow in recuperator - Google Patents

Description

The subject of the invention is a device for preheating air and more efficient use of fuel during operation of the cupola.

Devices for air heating and more efficient use of fuel during the operation of the cupola are known, however, they are disadvantageous because they do not provide stable burning of cupola gases, do not prevent gas temperatures from falling, do not allow further reduction of fuel consumption to create comparative heat supply conditions. service personnel.

The described device eliminates the aforementioned disadvantages in that it prevents the ingress of excessive amounts of cold air and the knocking out of flue cupola gases into the workshop through the loading window, which for this purpose is blocked by a door lined with refractory bricks. Opening and closing of the door when loading the charge and fuel is performed automatically, through the supply and storage of the crane and the fuel, which allows the temperature of the gases in the heat exchanger to rise.

On fi1g. 1 shows a diagram of the proposed device; and FIG. 2-diagram of the flow of gases in the area of the air heater.

In order to raise the temperature of the gases in the heat exchanger / and prevent cold air from sucking in, as well as knocking out waste, cupola gases or radiation through the loading window 2, the latter is automatically closed by a lined fire-resistant brick 3. Door 3 is opened during charging time and the top is completed using KpaiHa 4, which has a buffer of 5, waggled. on the lever about dperi 3 while moving “the wound to the loading zone. The closing of the door 3 is carried out by means of the load 7, acting through a cable on the door 3.

In order to direct the gases to the peripheral part of the shaft and create the best conditions for heating the heating elements
