Abstract

The high radiative coating technology was used in the coke oven 5 in Jiuquan Steel Co., The comparison test were conducted under different conditions in between the coke oven with and without coating. The results show that the heat transfer efficiency was increased 6.35% in coke oven 5, and the central temperature of coke cake increases 14℃, the flue gas temperature decreases 23℃ and saves coke oven gas 420.48×104 m3/a and the energy saving rate is 3.32%. The effective thermal efficiency of coke oven is increased 1.99%. The energy consumption for the coking process decreases 81.8kJ/kg coal(with 7%H2O), and CO2 emissions reduces 132.5×104 m3/a. Obvious economic and social benefits can be obtained.

Key words
