Utilization of waste heat from exhaust gas combustion of multi-purpose furnace

The role of the exhaust gas discharge device is to discharge the exhaust gas replaced by the new atmosphere in the furnace, and the role of the ignition burner is to fully burn the exhaust gas (mainly CO + H2) to generate CO2 + H2O, preventing pollution to the atmosphere and Risk of fire and explosion. Although this technology solves the problem of pollution emissions, few enterprises can effectively utilize the heat of long-term combustion exhaust gas, and directly emit it into the atmosphere, resulting in waste of energy.

It is estimated that each furnace's annual exhaust combustion heat energy is equivalent to 6t of standard coal combustion heat. If all equipment manufacturers can make full use of the exhaust combustion energy, the country can save at least 6000t of standard coal each year and reduce CO2 emissions by about 15000t. SO2 emissions are about 50t, and nitrogen oxide emissions are reduced by about 40t.

The 10-year equipment and process update of China's heat treatment industry has basically ended, and a new heat treatment revolution has begun. This is how to reduce equipment use costs, reduce energy consumption and emissions, and reduce environmental pollution.
