Bituminous Coal Characteristics and ApplicationsTraduire cette page

29/01/2020 · Bituminous coal can be categorized further by the level of volatile matter; it contains high-volatile A, B, and C, medium-volatile, and low-volatile. Volatile matter includes any material that is liberated from the coal at high temperatures. In the case of coal, the volatile matter may include sulfur and hydrocarbons.

Development of Low-Volatile Coal Firing Burner · Fichier PDF

However, low-volatile coal is difficult to burn stably in existing PC-firing boilers. IHI has developed a new burner that can burn low-volatile coal without using assist oil. The aim of the new burner is increasing emissions of volatile components by recirculating high-temperature furnace gas into the burner. This resulted in improved stable combustion. 69 Vol. 41 No. 2 August 2008 of the ...

The low volatile coking coal (LVCC) constitutes about 50% of the total coking coal reserves in India. These coals are characterised by high raw coal ash content (37 to 40%) and very difficult washability potential. The present production from LVCC is at least 16 to 18 mt per year, and is entirely despatched for non coking coal use.
