To improve combustion efficiency and reduce flue gas pollution in biomass-fired boilers,the com-bustion control system was taken as the research obj ect and the problems like poor robustness and low ac-curacy occurred in a power plant were investigated.Through analyzing the biomass combustion process,a control system using Siemens S7-300 programmable logic controller (PLC)was presented.The practical application shows this control system has good performance in stability and response speed,of which the maximum overshoot of the steam pressure is 0.5%,and the response time is 65 s.
