The effects of high primary airflow. Combustion. The immediate effect of high primary air (PA) flows is on combustion of pulverized coal. Burner coal nozzle exit velocities are vey dependant on ...

Once pulverized coal flows have been measured, ... Likewise, larger particles of coal have a greater tendency to rope (rather than mix with the air) through burner lines and coal nozzles. 2.

He says measuring pulverized coal flow to individual burners can provide the sort of efficiency and pollution control benefits that fuel injection provides to cars.

"The (coal) burner requires a base flame source (fired by waste oil or natural gas) to heat up the dryer and ignite the (pulverized) coal as it is fed into the burner," Catlett says.

AmerenUE’s 350 MW Meramec Unit 4 fires three rows of six B&W DRB-XCL front-fired pulverized coal burners equipped with Coen scanners.
