SCRAPER ASSEMBLY VENTURI OUTLET The outlet venturi is located at the top of the mill just below the mill discharge valves The venturi distributes the pulverized coal into the fuel lines as the coal exits the mill. The new design outlet venturi distributes the coal and air mixture more evenly and with less turbulence to the fuel outlets.

Bimodal distribution of outlet temperature is caused by milled fuel type. During periods of coal and biomass comilling, the mill outlet temperature demand has been set at 115°C. If the mill was gridding, only coal mill outlet temperature demand has been set at 105°C. Histograms are presented in Figures 2 and 3.

The jet venturi is the most basic wet scrubber. In this setup, a pressurized liquid is passed through a nozzle and expands as the pressure decreases to atmospheric conditions. This creates an area of low pressure, which draws the gases into the head of the jet venturi. This twophase mixture is compressed in the converging nozzle.
