Coal Properties and its influence on Boiler Pankaj

Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal. • Other methods like Macarel analysisCoal Grades | Ministry of Coal, Government of India,The gradation of non-coking coal is based on Useful Heat Value (UHV), the gradation of coking coal is based on ash content and for semi coking / weakly coking coal it is based on ash plus moisture content , as in vogue as per notification.Coal Classification, Blending, and Requirement,Coal Classification, Blending, and Requirement.
