Honeycomb Ceramic Regenerator (For Regenerative Heating Furnace)
The technology is to make two regenerative alternating heat absorption exotherms through the reversing device, to recover the heat of the flue gas to the maximum limit, and then to heat the combustion air and gas in the furnace to above 1000 C, it can achieve stable ignition and efficient combustion even the low calorific value of the inferior combustion, saving fuel up to 40-70 °C. The output will be increased by more than 15 °C, the oxidation loss of the steel embryo will be reduced by more than 40%, the NO2 emission will be less than 100 pm, and the exhaust gas temperature will be lower than 150″C, which greatly reduces the greenhouse effect of the earth’ s atmosphere. If most of industrial furnaces in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will greatly alleviate the shortage of energy and improve the living environment of human beings. Since its launch in the market, it has achieved good results and is favored by the steel smelting industry.
