The heat taken away by the traditional industrial furnace exhaust emissions usually accounts for 50% to 70% of the fuel supply. Although many industrial furnaces are equipped with air preheaters, due to technology, price, life, payback period and other reasons, the air can usually only be preheated to 300 to 500 ° C, and the energy saving rate is only 15% to 30%. Even so, 30% to 50% of the heat is emitted into the atmosphere with the exhaust gas.
Our company successfully developed a new generation of high-efficiency regenerative industrial furnaces using high-temperature and low-oxygen combustion technology, which not only overcomes the shortcomings of conventional industrial furnaces, but also improves the waste heat recovery rate to 80% to 90%. At about 1000 ° C, the exhaust temperature of industrial furnaces is lower than 150 ° C, reaching the limit of waste heat recovery. What's more, the high-temperature and low-oxygen combustion technology is used to reduce the slab burnout rate from 3% using conventional heating technology. 5%, reduced to less than 1%, thereby greatly improving economic benefits.
The successful development of a new generation of high-efficiency regenerative industrial furnaces has broken the heating mode of traditional industrial furnaces, solved a series of problems such as high production and low consumption of industrial furnaces, ultra-low heating value gas utilization and environmental protection, and high-temperature heating in various industrial sectors Furnace and heat treatment furnace can achieve 40% energy saving and 30% increase in output.
Our company successfully developed a low-nox high-efficiency thermal storage industrial furnace with independent intellectual property rights using high-temperature air combustion technology. Including various heating furnaces, heat treatment furnaces, forging furnaces, various ceramic down flame furnaces and incinerators. The fuel used can be blast furnace gas, mixed gas, coke oven gas, natural gas, liquefied petroleum gas and fuel oil.
Advantages of high temperature air combustion technology:
1Smoke temperature is low, up to 130 ℃
2. The heat recovery rate is above 90%
3.Save energy 30 ~ 60%
4. Miniaturization of furnace body, saving cost
5.Low nox emissions;
6.Less slab oxidation loss rate
