As you can see from the live video.，Shandong yiran energy-saving environment protection co., ltd It is an important heating equipment before metal forging. It uses natural gas as fuel to heat metal materials through high-temperature flame and smoke generated by combustion to meet the requirements of forging process.。

4、Working principle of Pit type heating furnace

Pit type heating furnaceat the start of the operation,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.，usually used in light industry, surface treatment, heat treatment, metallurgy, automobile and other fields，the advantage is The use of clean and environmentally friendly natural gas as fuel effectively avoids the adverse effects of chemical reactions between impurities such as coal-fired furnaces and forgings during heating. At the same time, natural gas has high calorific value and high combustion temperature, and the combustion temperature can be further increased by preheating air and fuel. In addition, the gas forging heating furnace also has good heat loss control ability and intelligent control system, which can accurately adjust the ratio of air to natural gas, ensure full combustion of natural gas, and reduce mechanical incomplete combustion and chemical incomplete combustion.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Using regenerative combustion system or advanced burner design can realize the uniform distribution of temperature in the furnace, ensure the uniform heating of metal materials and improve product quality.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、The user interface is friendly, and the operator is easy to use. At the same time, the equipment also has the function of fault diagnosis and alarm, which can find and deal with abnormal situations in time.，the product looks atmospheric.，The overall structural design is relatively simple and compact.，it is mainly composed of furnace chamber, ventilation system, combustor, furnace chamber and ventilation system。

5、Pit type heating furnace structure

The Pit type heating furnace has the following structure

1. combustor

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

2. Radiation chamber

The heat load of the main place for Pit type 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.

3. convection chamber

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

4. ventilation system

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

5. Waste heat recovery system

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