CONTROL OF CFB BOILER IN LOAD REJECTION TEST OF 300 MW UNIT
the control of CFB boiler has to adjust coal feed at 30 min before test due to its large thermal inertia
maintaining the low value operation of main steam parameters:at 10 min before test
the parameters must be changed to hand control;at 300~30 s before test
the coal feed as well as the primary and secondary air have to be reduced.After the load rejection
the temperature of main steam and reheated steam has to be controlled between 500~560 ℃.The 50% load rejection test and 100% load rejection test have been carried out on a DG177/17.4-Ⅱ1 type CFB boiler of 300 MW unit in Jingmei Fenghuanglin Power Plant
