The No. 2 Unit (410 t/h, 100MW) of Jiaozuo Danhe Power Generation Co., Ltd., was put into use in 1975. To stabilize the combustion without oil at low load, eight original designed burners which had been placed in the middle and bottom level on the No. 2 boiler, were replaced with the controllable pulverized coal (PC) rich/lean burners. The practice of operation after the retrofit proves that stable combustion can be achieved at 50% load without support oil, even at 40% load. Boiler efficiency increases to 91.15% from 89.92% at half load (50MW). It is shown the novel burners can make a good performance and combustion can keep stable even when the character parameters of coal change in the large scope. Generally the application is successful and economic benefits will be greatly achieved from now on.
