1、Brief introduction of Rotary kiln heating furnace

Rotary kiln heating furnaceIt 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.，the product looks atmospheric.，can be customized according to user's needs.。

2、Structural characteristics of Rotary kiln heating furnace

The Rotary kiln heating furnace has the following structure

1. Waste heat recovery system

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

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. Radiation chamber

The heat load of the main place for Rotary kiln 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、Advantages of Rotary kiln heating furnace principle

Rotary kiln heating furnaceThe 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.，be loved by our customers.。

5、Functional advantages of Rotary kiln heating furnace

Rotary kiln heating furnaces have the following advantages.

1. Uniform heating

The Rotary kiln heating furnace adopts regenerative combustion system or advanced burner design, which can realize uniform distribution of temperature in the furnace, ensure uniform heating of metal materials and improve product quality.

2. Wide application range

The Rotary kiln heating furnace is suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.

3. Intelligent control

The Rotary kiln heating furnace is usually equipped with an intelligent control system, which can automatically adjust the parameters such as gas supply and air flow according to the heating demand, and realize accurate control of the temperature and atmosphere in the furnace.

4. Reduce operating costs

The efficient combustion and waste heat recovery system of the Rotary kiln heating furnace can significantly reduce energy consumption, thus reducing operating costs.

5. clean energy

Natural gas, as a clean energy source, produces less waste gas and dust after combustion, which has little pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.
