1.Power plant boiler fuel with wide range adaptability burnt coal particles mixed up sufficiently ,so the newly sent coal particle are rapidly heated to ignition Circular flow bed (CFB)boiler make the newly sent coal particle and the already temperature and burm
2.Power plant boiler lean combustion technology circulating fluidized bed boiler in the furnace by adding limestone, can be a simple desulfurization in the furnace, when the calcium and sulfur molar ratio of 2, the desulfurization efficiency can reach more than 84%, due to the operation of the use of graded air And low temperature combustion, so the amount of NOx generated very low. Thus greatly reducing SOx and NOx emissions, improve the atmosphere and environmental quality.
3.Power power boiler could adjust its load in a wide range. Lowest load can be reduced t 30% of full capacity.
