volatile division of chain boiler coal

Volatile Matter - an overview | ScienceDirect Topics

Volatile matter is defined as the gases driven off when coal is heated to 950°C (1742°F) in the absence of air under specified conditions and is consisted of short and long chain aliphatic carbon atoms (linked in open chains) or aromatic hydrocarbons (one or more six-carbon rings characteristic of benzene series) and some sulfur.

What is the effect of volatile matter on boiler combustion

Mar 13, 2020 · Coal with high volatile matter is easy to catch fire, and the combustion is stable and complete. So, the fineness of pulverized coal can be coarser. The disadvantage is that it is easy to deflagrate. Coal with low volatile matter and high carbon content is not easy to ignite and burn, so the fineness of the pulverized coal is required to be finer.

PERCENT VOLATILE CONTENT IN COAL American coals have a volatile content range on a dry and ash free basis of anywhere from 2 to 50%. The 2% lower limit, of course, is anthracite coal. This coal characteristic directly effects the combustibility of the pulverizer product. With lower volatile content, the required fineness increases.

Aug 28, 2018 · Volatile matter indicates how well the coal will burn. Volatile matter consists of hydrocarbons and other gases that are produced when a sample of dry coal is heated. Coals with less than 15% volatile matter may be difficult to burn and require special procedures for efficient combustion.
