摘要：Fuel combustion calculation is an important basic work of boiler performance test and analysis. During the process of combustion calculation, solving excess air ratio and actual volume of dry flue gas are key objectives. Current method is to firstly calculate excess air ratio, then calculate actual volume of dry flue gas. And in order to solve excess air ratio, almost all fue gas composition need to be measured, which will not only increase the workload of measurement, but also reduce the accuracy of calculation results. To this end, a new combusion calculating method is proposed in this paper which solves actual dry flue gas ratio through oxygen content in flue gas, thus actual volume of dry flue gas is calculated. Finally, the excess air ratio is obtained through acutal volume of dry flue gas. By the new method, the flue gas composition measure items can be reduced to only oxygen content, but it will not reduce the precision of combustion calculation.
