Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler startup.

coal. We do not recommend burning wet coal, however, we realize if it''s the only coal you have it is better to burn it than freeze. If you must burn wet coal, the feed rate must be increased in order to get the same size fire. As the wet coal in the hopper dries out, the feed rate must be decreased. If you don''t, the feeder will overfire
