How to choose the dust collector for coal-fired boilers

The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

How Coal Fired Boiler works - YouTube

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 …
