| Abstract: | To study the thermal efficiency and NOx mass concentration in exhaust gas of a 1 913 t/h boiler, test analysis was made to the effects of operation oxygen quantity on the thermal efficiency and NOx generation of boiler. Results indicate that, under the premise of guaranteeing the safe and economic operation of boiler, the reduction of oxygen volume fraction in exhaust gas can not only improve the thermal efficiency of boiler but also decrease the NOx mass concentration. In addition, an optimized operation curve of oxygen quantity was finally recommended. |
