On coal-fired boilers, several kinds of deposit may be formed: slag type, alkali-matrix type (bonded), and the phosphate type, only obtained from coals with a high phosphate content (see Chapter 20). Alkali compounds and phosphates are volatilized and condensed on cooler metal surfaces; the alkalis react with sulphur dioxide and sulphur trioxide forming sulphates which bond to the metal and pick up fly-ash on their molten surfaces and phosphates behave similarly.

were also used to predict the coal combustion and NOx formation at the exit of a double air register swirl pulverized-coal burner. The results indicate that a pulverized coal concentrator installed in the primary air tube of the burner has a strong effect on the coal combustion and NOx formation.
SNCR on all types of coal-fired electric utilities and large industrial boilers. 1.2 Process Description SNCR is based on the chemical reduction of the NO x molecule into molecular nitrogen (N 2) and water vapor (H 2 O). A nitrogen based reducing agent (reagent), such as ammonia or urea, is injected into the post combustion flue gas.
