Abstract：In response to the low waste heat recovery efficiency issue in the negative electrode coating oven of a certain lithium-ion power battery company,the exhaust valve is closed,a surface cooler is added to allow the graphite in the exhaust gas to be eliminated through condensation wate,and the fresh air input is reduced.The results indicate that the supply air temperature of the air supply fan increased from 45 ℃ to 65 ℃.Natural gas consumption was reduced by 160 400 m3/a,resulting in a cost reduction of 818 000 yuan/a and a decrease in carbon emissions by 346.46 t/a compared to the original conditions.
