循环流化床高浓度富氧燃烧试验研究
Experimental Study on Oxy-fuel Combustion With High Oxygen Concentration in a Circulating Fluidized Bed
摘要
Abstract
In order to investigate the effects of combustion temperature and atmosphere on the combustion stability, CO2 concentration and gaseous pollutants emissions in flue gas, in a 0.1 MW circulating fluidized bed (CFB) oxy-fuel combustion facility, oxy-combustion experiments with Datong coal were carried out at O2/CO2 and O2/ recycled flue gas (RFG) atmosphere with high oxygen concentration. The test results show that when the oxygen concentration of the primary air ranges from 49.6%to 55.2%and that of the secondary air is in the range from 45.3%to 51.7%, the CFB oxy-fuel combustion facility maintains stably at O2/RFG atmosphere. In flue gas, CO2 concentration can reach above 90%, SO2 concentration is 87 to 197 mg/MJ, N2O concentration is 48 to 78 mg/MJ, and NO concentration is only 19 to 44 mg/MJ. Compared with the result of O2/CO2 combustion, the concentration of CO and SO2 increases to a certain degree, while N2O concentration decreases obviously, and NO concentration basically remains the same.关键词
