Introduction to Indirect roasting furnace and heating furnace structure principle

Indirect roasting 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 Adopting advanced combustion technology and control system can realize full combustion of natural gas and improve combustion efficiency. At the same time, some equipment is also equipped with waste heat recovery system, which can further recycle the waste heat in exhaust smoke and improve energy utilization efficiency.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、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.，features include energy-efficient, Stable and reliable, Easy to maintain, Easy to control and Strong adaptability，it is an ideal choice for customers to buy Indirect roasting furnace。

Indirect roasting furnace

Indirect roasting furnaceis a popular Indirect roasting furnace，at runtime,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.。
