Introduction to Multi stage natural gas trolley furnace and heating furnace working principle

Multi stage natural gas trolley furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，is based on One-combustion energy saving is a Multi stage natural gas trolley furnace newly developed by One-combustion energy saving。The following is to introduce the Multi stage natural gas trolley furnace:

1、Brief introduction of Multi stage natural gas trolley furnace

Multi stage natural gas trolley furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.。

2、Multi stage natural gas trolley furnace structure

The Multi stage natural gas trolley furnace structure is introduced as follows:

1. Radiation chamber

The heat load of the main place for Multi stage natural gas 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.

2. furnace chamber

A space for holding metallic materials for heating.

3. combustor

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

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. ventilation system

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

3、Structural characteristics of Multi stage natural gas trolley furnace

The Multi stage natural gas trolley 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. convection chamber

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

3. furnace chamber

A space for holding metallic materials for heating.

4. 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.

5. Radiation chamber

The heat load of the main place for Multi stage natural gas 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.

4、Video analysis of Multi stage natural gas trolley furnace

The following is the live video of Multi stage natural gas trolley furnace designed and produced by One-combustion energy saving for users, from which we can see the the advantage is Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.、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.、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.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency. of One-combustion energy savingMulti stage natural gas trolley furnace.。
