Abstract:

Research of mode of air distribution and total air volume for a 330MW boiler in a certain power plant,were carried out to analysis the influence of mode of air distribution and total air volume variation on concentration of NOx emission and economical operation of the boiler. Result of the test showed that under the constant Unit load, change the air distribution mode, under 250MW load, the efficiency of the boiler at working condition T2 is similar to that of the boiler at working condition T1, concentration of NOx emission decreased by 40mg/m3, under 300MW load, the efficiency of the boiler at working condition T4 is 0.28% higher than that of the boiler at working condition T3, concentration of NOx emission decreased by 20mg/m3.Under the condition that the unit load and other operation parameters are basically invariable,change the total air volume,under 300MW load, the efficiency of the boiler at working condition T6 is 0.19% higher than that of the boiler at working condition T5, concentration of NOxemission decreased by 40mg/m3. Under 250MW load, the efficiency of the boiler at working condition T9 is 0.16% higher than that of the boiler at working condition T7, concentration of NOxemission increased by 40mg/m3. Under 190MW load, the efficiency of the boiler at working condition T12 is 0.24% higher than that of the boiler at working condition T10, concentration of NOx emission decreased by 60mg/m3.
