4、Structural advantages of Three-stage steel rolling heating furnace

The Three-stage steel rolling heating furnace has the following structure

1. Radiation chamber

The heat load of the main place for Three-stage steel rolling heating 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.

2. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating 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. 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.

5. Waste heat recovery system

Recover the waste heat in the exhaust gas of heating furnace to improve the energy utilization efficiency.
