1. How to reduce the combustible content in slag in coal-fired boilers. What measures should be taken for adjustment.
1. Improve the fineness of coal powder. 2. Use hot air for feeding coal powder in order to reduce or eliminate air leakage in the coal grinding system. 3. Improve the quality of coal, use less low-quality coal; mix coals when necessary so that the coal fed into the furnace can ignite more easily and burn completely. 4. Optimize combustion by controlling the amount of oxygen; during operation of the four-corner circular burners, it is necessary to avoid flame deviation or sticking to the walls; modify the burners if needed to improve combustion efficiency
