Answer 1

Answer:

Proximate analysis of a fuel provides the percentage of the material that burns in a gaseous state (volatile matter), in the solid state (fixed carbon), and the percentage of inorganic waste material (ash), and is therefore of fundamental importance for biomass energy use .

Answer 2

Proximate analysis of coal signifies the chemical composition of a coal sample.

Proximate Analysis of Coal :-

• It involves the determination of moisture content ash content, volatile matter and fixed carbon.
• It is used to determine the rank of coals.
• This analysis helps to show the ratio of combustible with incombustible constituents.
• They provide the buying/selling basis and evaluate the coal sample for various purposes.
• An increase in Fixed carbon content helps to build a good rank of coal.
