Anthracite has the highest calorific value. and South African coal is best in the world.
Anthracite coal is harder than Lignite.
Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
It varies based on the type and grade of coal. The heat value is less for bituminous than for anthracite, etc.
The finest quality coal is called the bituminous coal, it is finer than the lignite coal.

Gross calorific value of coal
Coal
what is the differnence between gross calorific value and useful heat value
gross calorific value
To calcualte NCV you need calorific value on GAR, H on gar and Total moisture.
Lignite is a kind of coal (brown coal).
Anthracite coal is harder than Lignite.
lignite is another word for coal
Lignite is a mixture. It is a soft coal.
Useful heat value(UHV) pricing mechanism of coal deducted ash and moisture content from standard formula and in this coal is categorised into 7 grades. Gross calorific value(GCV) of coal has 17 grades and prices are linked to the actual calorific value/quality of coal-by latika joshi
