Preventive measures for coking of biomass boilers 5
Try to keep the primary and secondary wind speeds of each burner of the biomass boiler consistent.
Try to keep the primary and secondary wind speeds of each burner of the biomass boiler consistent, and at the same time control the more appropriate primary air coal powder concentration and maintain the appropriate coal powder fineness to maintain the uniformity of the furnace temperature field distribution. Analysis of coal powder found that the coal powder fineness increased and the coal powder became coarser. The coarse particles in the coal powder were easily separated from the coal powder airflow and collided with the water-cooled wall; in addition, it takes a long time for the coarse particles to burn out, so they often stick to the wall to create a reducing atmosphere and increase the probability of slagging.
