4、Double car furnace structure

The Double car furnace structure is introduced as follows:

1. convection chamber

The material is heated by convection heat transfer of high temperature flue gas discharged from the radiation chamber. Flue gas washes the tube wall of the furnace tube at a high speed to carry out effective convection heat transfer, and its heat load accounts for about 20%-30% of the whole furnace. The convection chamber is generally arranged above the radiation chamber, and some are placed on the ground alone. In order to improve the heat transfer effect, nail head tubes or finned tubes are often used in furnace tubes.

2. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

3. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

4. Radiation chamber

The heat load of the main place for Double car furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

5. furnace chamber

A space for holding metallic materials for heating.

Double car furnacethe product looks beautiful.，at work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.。
