For pulverized coal-fired boilers, there are roughly two co-firing options. One is to simply pulverize the woody biomass in existing mills and combust the pulverized coal-biomass mixture fuel in a boiler, using the existing burner.

Nov 27, 2019Classifiers • The flow of coal particles through a classifier is several times the amount of coal flowing to the burners because of the large amount of coal recirculated within a pulverizer. For example, if a pulverizer is operating at 100,000 lb/hr coal feed to the burners, as much as 300,000 lb/hr or more may be flowing through the
