3、Preheating trolley furnace principle

Preheating trolley furnacein the course of work,Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.，It is an efficient, energy-saving and environment-friendly metal heating device.，the product looks atmospheric.，it has the characteristics of Strong adaptability, Stable and reliable, energy saving and environmental protection, Easy to control and Easy to maintain，It has a wide range of uses, and is often used inImprove production efficiency,Metal heat treatment,Metal heat treatment,Improve production efficiency,Metal tempering and so on。

4、Structural characteristics of Preheating trolley furnace

The Preheating trolley furnace structure is introduced as follows:

1. convection chamber

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

2. 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.

3. combustor

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

4. Radiation chamber

The heat load of the main place for Preheating trolley 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. furnace chamber

A space for holding metallic materials for heating.

Preheating trolley furnace

Preheating trolley furnaceat work,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.，The overall structural design is simple and novel.，structure mainly includes: combustor, ventilation system, Radiation chamber, recovery of waste heat, convection chamber and so on。
