Flue gas waste heat utilization equipment:
Annealing furnace is a kind of heat treatment furnace, which is widely used in production processes requiring central heating such as chemical industry, petroleum, food, metallurgy, machinery, light industry, electricity, etc. Cold rolled stainless steel strip needs annealing after cold rolling. Cold rolled stainless steel continuous annealing furnace is the key equipment of cold rolled stainless steel direct rolling annealing pickling line, and is the key process in the production field of cold rolled stainless steel products. At present, cold rolled stainless steel continuous annealing furnaces use open flame burners for direct heating, and the energy medium consumed is combustible gas. Energy saving and consumption reduction of annealing furnaces is an important way for enterprises to reduce production costs, save energy, and increase economic benefits. But at present, not only is there a large amount of waste heat from annealing furnace heating not directly discharged into the atmosphere, Moreover, the waste heat of stainless steel strip has never been used. The high output of stainless steel annealing furnace and the high annealing temperature of strip steel have resulted in a large waste of waste heat and increased energy consumption and enterprise operating costs. After flue gas treatment, there are still a lot of waste heat resources that have not been fully recycled. Although direct high-temperature discharge will not cause environmental pollution, it will cause a lot of energy waste. Hebei Yongxin Boiler can pass the annealing furnace Flue gas waste heat recovery equipment To reduce heat source waste, Waste heat recovery unit The main principle is very simple. Through the heat exchange between high-temperature flue gas and low-temperature water or gas medium, the temperature reduction will be discharged from the chimney. The recovered waste heat energy can be used as
Heat transfer oil
Hot water, steam, air preheating energy use. Hebei Yongxin Boiler Production
