Lime kiln air gas preheater

Our company has been engaged in utilizing the heat of high-temperature or medium-temperature flue gas generated by industrial kilns, boilers, coking furnaces, blast furnaces, and metallurgical furnaces for many years. It exchanges heat through heat exchangers, recovers its heat, and heats water, air, or gas. The hot water steam or high-temperature air generated can meet the needs of hot water heating for domestic use, steam preheating for fuel and combustion-supporting air or food material drying for power generation.

According to the process characteristics of gas-fired lime kilns, suitable air heat exchangers and gas heat exchangers have been developed, which use high-temperature flue gas to preheat the air and gas entering the furnace while simultaneously preheating the high-temperature flue gas. Air-to-air heat exchange technology for cooling. Actual tests show that the flue gas temperature drops from ℃ before heat exchange to ℃ after heat exchange, and % of the waste heat of the flue gas is absorbed by the air and gas, effectively improving the energy utilization rate of the gas-fired lime kiln.

Lime kiln flue gas waste heat recovery air gas preheater description:

Due to the low calorific value of blast furnace gas, in order to ensure sufficient roasting temperature in the kiln, it has to be Ensure the supply of effective combustible gas by increasing the total supply of gas. As the amount of low-temperature gas entering the furnace increases, the furnace temperature decreases. At the same time, the total amount of gas entering the furnace increases, resulting in an increase in the amount of exhaust gas after combustion. In addition, during the lime roasting process, a large amount of
