4、Structural characteristics of Regenerative heat treatment chain furnace

The Regenerative heat treatment chain furnace has the following structure

1. 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.

2. 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.

3. combustor

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

4. ventilation system

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

5. convection chamber

The high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

Regenerative heat treatment chain furnaceAdopting advanced combustion technology and control system can realize full combustion of natural gas and improve combustion efficiency. At the same time, some equipment is also equipped with waste heat recovery system, which can further recycle the waste heat in exhaust smoke and improve energy utilization efficiency.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.，is a common Regenerative heat treatment chain furnace，Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.。
