Introduction to Pit type heating furnace, heating furnace specifications, model parameters

Pit type heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，the advantage is Natural gas is used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.、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.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、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.，is a kind of high quality and low price Pit type heating furnace，at the start of the operation,The high-temperature flame and flue gas generated when fuel (natural gas) burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature.，is a Pit type heating furnace newly developed by One-combustion energy saving。The following is to introduce the Pit type heating furnace:

1、Brief introduction of Pit type heating furnace

3、Pit type heating furnace structure

The Pit type heating furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Waste heat recovery system

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

3. ventilation system

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

4. Radiation chamber

The heat load of the main place for Pit type 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.

5. furnace chamber

A space for holding metallic materials for heating.

4、Pit type heating furnace principle

Pit type heating furnaceHeat 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.，has been favored by more and more customers.。
