What is the Environmental Impact of Coal?

Jun 25, 2019Coal has long been a reliable source of American energy, but it comes with tremendous costs because it is incredibly dirty. The same chemistry that enables coal to produce energy—the breaking down of carbon molecules—also produces a number of profoundly harmful environmental impacts and pollutants that harm public health.

How accurate primary airflow measurements improve plant

The immediate effect of high primary air (PA) flows is on combustion of pulverized coal. Burner coal nozzle exit velocities are vey dependant on the level of PA flow. High PA flows cause excessive nozzle exit velocities and hamper the ability of secondary air fed around the PA/coal stream to mix with the coal.
