Abstract

The flue gas compression system in a 300MW oxy-coal fired boiler unit is taken as an object of study. By the leakage test of quad-section rotary gas-gas preheater on B-MCR condition, the influence from the leakage on the operation parameters of the flue gas compression system were analyzed. The results present that the leakage of the quad-section rotary gas-gas preheater leads to the temperature drop of the exhaust flue gas, which is beneficial to the elimination of flue gas moisture. But the increase of compressed flue gas flow leads to the increase power of flue gas compressor. In addition, with the increase of air leakage rate of quad-section rotary gas-gas preheater, the rise of flue gas compressor outlet pressure has an influence on the operation performance of deep dehydration equipment, which is unbeneficial to further purification and recovery of the compressed gas.
