Reduction of environmental pollution and pollution caused by coal combustion

摘要

Powder components containing calcium, alumina, silica, iron, magnesium, and halogen adsorbents are used in combination during coal combustion to produce environmental benefits. Adsorbent is added to the coal before combustion and / or added to the flame or downstream of the flame. Especially when using sub-bituminous and lignite coals, the alkalinity and chlorine of the powder is minimized to reduce undesirable contamination.
