The regenerative steel rolling heating furnace uses gas or natural gas as fuel

The basic principle of regenerative burner operation: The regenerative burner designed by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. first heats the regenerative body, then introduces air, and heats the air to high temperature. It is then mixed with flue gas in the furnace (to reduce oxygen content, the purpose is to reduce nitrogen oxide content), and then mixed with fuel for combustion. The regenerative burner is designed and installed in pairs, with one used to heat air and the other heated by flue gas. After a cycle, the regenerative chamber that heats the air cools down, while the regenerative chamber that is heated by the flue gas increases its temperature. In this way, through the directional valve, the two regenerative chambers exchange their functions. At this time, the original exhaust port has now become a burner, and the original nozzle has now become a smoke exhaust port.

The main characteristics of high-temperature air combustion technology are:

(1) Adopting a high-temperature air flue gas waste heat recovery device, alternating between air and flue gas, allowing them to flow through a heat storage body and recover the sensible heat of high-temperature flue gas, thus achieving waste heat recovery;

(2) Preheating the combustion air at a temperature level above 1000 ℃ to form a new type of flame that is completely different from traditional flames (such as diffusion flames and premixed flames), creating an excellent uniform temperature field distribution in the furnace;

(3) By organizing combustion in a lean oxygen state, the excessive generation of high-temperature thermal nitrogen oxide NOx is avoided. Therefore, this technology has produced significant economic and social benefits in practical applications.

Overview of regenerative steel rolling heating furnace:

According to the different classifications of fuels used in steel rolling heating furnace equipment, they are: gas rolling heating furnace, oil rolling heating furnace, gas rolling heating furnace. The detailed classifications of gas rolling heating furnace are: natural gas rolling heating furnace, petroleum liquefied gas rolling heating furnace, blast furnace gas rolling heating furnace, coke oven gas rolling heating furnace, converter gas rolling heating furnace, blue carbon gas rolling heating furnace, yellow phosphorus tail gas rolling heating furnace Gas generation furnace, steel rolling heating furnace, etc. According to energy-saving requirements, regenerative steel rolling heating furnaces are classified as: regenerative natural gas steel rolling heating furnace, regenerative liquefied gas steel rolling heating furnace, regenerative blast furnace gas steel rolling heating furnace, regenerative coke oven gas steel rolling heating furnace, regenerative converter gas steel rolling heating furnace, regenerative blue carbon gas steel rolling heating furnace, regenerative gas producer gas steel rolling heating furnace.

The classification of oil-fired steel rolling heating furnaces is: diesel steel rolling heating furnaces, heavy oil steel rolling heating furnaces, mainly used in countries and regions in Africa and the Middle East. The diesel steel rolling heating furnace can be designed as a regenerative diesel steel rolling heating furnace.

Investment analysis: Using natural gas as fuel, design a regenerative steel rolling heating furnace, with a gas consumption of 35-40 cubic meters per ton of steel (reference value). One time investment analysis: two cooperation modes: labor and material contracting and labor and material contracting. Specific design and construction are tailored according to user needs. Zhongwei Environmental Protection has industrial furnace design and construction qualifications to ensure the overall quality of industrial furnaces.
