5、Preheating heating furnace structure composition

The Preheating heating furnace structure is introduced as follows:

1. ventilation system

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

2. Waste heat recovery system

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

3. furnace chamber

A space for holding metallic materials for heating.

4. Radiation chamber

The heat load of the main place for Preheating 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.

5. 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.
