What is a Protective gas natural gas trolley furnace? Introduction to the Working Principle of heating furnace

Protective gas natural gas trolley furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，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.、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.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.，is a kind of high quality and low price Protective gas natural gas trolley furnace，the main features are energy saving and environmental protection, Stable and reliable, Strong adaptability, energy-efficient and Stable and reliable，the product looks atmospheric.。The following is to introduce the Protective gas natural gas trolley furnace:

1、Brief introduction of Protective gas natural gas trolley furnace

Protective gas natural gas trolley furnaceIt is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short time.，It has a wide range of uses, and is often used inMetal melting and casting,Metal forging heating,Improve production efficiency,Metal heat treatment,Metal tempering and so on，at work,Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.，is an advanced Protective gas natural gas trolley furnace developed by our company in combination with the actual situation of the industry。

2、Protective gas natural gas trolley furnace structure composition

The Protective gas natural gas trolley furnace has the following structure

1. Radiation chamber

The heat load of the main place for Protective gas 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. 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. 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. Waste heat recovery system

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

5、Protective gas natural gas trolley furnace principle

Protective gas natural gas trolley 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.，is a popular Protective gas natural gas trolley furnace。
