| Abstract: | Based on the structure and combustion features of a 1 177 t/h circulating fluidized bed boiler in Guohua Ningdong Power Generation Co.,Ltd.,an analysis was performed to the protection control logic of its main fuel trip(MFT),while a comparison made between circulating fluidized bed boiler and conventional coal-fired boiler.In the MFT protection control logic,there are various protections provided,such as the loss of all flame,primary air flow less than minimum fluidization air flow and high or low bed temperature. |
