By taking the coal pulverizing system of a 1 025t/h oxy-fuel boiler firing lignite with high moisture and low sulfur as an example
process flow of the coal pulverizing system and mill type selection were designed
using the first flue gas recirculation as the desiccant.Moreover
thermal dynamic calculation was carried out to ascertain parameters values like the coal temperature and moisture at mill outlet.The results show that
the MPS200HP-Ⅱtype mill can satisfy the requirements of coal pulverizing system in oxy-coal combustion boilers which fire high-moisture lignite.Variation of moisture in raw coal has great influence on temperature and moisture of the pulverized coal at the mill outlet.
