The No.2 unit (670/H, 200MW) at Hebi Wanhe Power Generation C o. Ltd., was put into use in 1992. This is a coal-fired boiler with tangential fired method. The design coal is Hebi lean coal. To stabilize the combustion without oil at low load, eight original designed burners placed to No. 2 and 3 level on the No.2 boiler were replaced with the controllable pulverized rich/lean ones developed by the Institute for Thermal Power Engineering (ITPE) of Zhejiang University. The practice of successive operation shows that stable combustion can be achieved at 50% load without support oil, even at 45% load. The combustible matter in fly ash decreased to 1.12% and 1.17% from 1.83% and 1.32%, respectively at full load (200MW) and half load (100MW). The application has obvious economic benefits.
