A composition and method for reducing the level of mercury, nitrogen oxides and / or sulfur oxides released into the atmosphere upon combustion of a mercury-containing fuel such as coal. 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. [Selection figure] None |
