What is heat value of coal?
The calorific value of coal is measured for almost all coal samples. It is a measure of the heating ability of a coal and is needed to estimate the amount of coal needed to produce a desired amount of heat.
What is the calorific value of coal gas?
The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (i.e. to 0oC and under a pressure of 1,013 mbar).
Fuel Calorific Values.
|Natural gas||12500 kcal/kg|
|Brown coal||3500 kcal/kg|

Calorific Value of Fuel.
|Fuel||Calorific Value Of Fuel( Approximately)|
What are the 4 grades of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
How much is a ton of coal?
In 2019, the national average sales price of bituminous, subbituminous, and lignite coal at coal mines was $30.93 per short ton, and the average delivered coal price to the electric power sector was $38.53 per short ton.
Why coal gas is not used for cooking?
As coal is also a fossil fuel, it is produced in nature from the dead & decayed remains of plants and animals after millions of years of processes. So we cannot use them on a regular basis as a cooking fuel to check their depletion.
What is SI unit of calorific value?
Calorific value provides the amount of energy that is released when a fuel or material undergoes the process of combustion. It is usually a measure of energy. The SI unit (international system of units) of calorific value is Joule/Kg or Kilo Joule/Kg.
