What are the ways to burn coal slime in circulating fluidized bed boilers?

　　The coal slime burned in the circulating fluidized bed boiler can be mixed and burnt directly with raw coal through the coal conveying belt, or it can be sent into the furnace by the slime pumping system through a dedicated pipeline for combustion. The method of coal slime entering the furnace should be determined based on the characteristics of coal slime. If the content of sand and gravel in the slime is relatively large. This type of slime is more suitable for direct mixing into raw coal after drying; If the slime is in the form of a paste and the water retention is good, this type of slime is more suitable for transportation in a pipeline system.
