What is a Natural gas tube heating furnace? Introduction to the Working Principle of Forging furnace

Natural gas tube 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 following is to introduce the Natural gas tube heating furnace:

1、Brief introduction of Natural gas tube heating furnace

Natural gas tube heating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，Easy to maintain,Strong adaptability,Easy to control,energy-efficient,Stable and reliable，Cheap and high quality。

2、Structural characteristics of Natural gas tube heating furnace

The Natural gas tube 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. furnace chamber

A space for holding metallic materials for heating.

3. 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.

4. combustor

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

5. ventilation system

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

4、Natural gas tube heating furnace structure

The Natural gas tube heating furnace structure is introduced as follows:

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. Radiation chamber

The heat load of the main place for Natural gas tube 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.

As you can see from the live video.One-combustion energy saving features include energy saving and environmental protection, Easy to maintain, energy saving and environmental protection, Strong adaptability and energy-efficient。

Natural gas tube heating furnaceit has the functions of normalizing, quench, anneal, heat treatment and hardening and tempering，is a Natural gas tube heating furnace，in 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.。
