What is the difference between GCV and UHV of coal?

In GCV( Gross calorific Value) it is asumed that moisture & other elements present in coal(besides coal) can be used for generation of Heat and hence ‘ gross’. While in UHV( useful heat value) it is assumed that those elements cant produce heat and so are eleminated for the purpose of heat calculation.

What is GCV and NCV of coal?

GCV, Gross calorific value of fuel, Kcal/Kg. NCV, Net Calorific Value of fuel, Kcal/Kg. H2%, Hydrogen Percentage by Weight in the fuel. M%, Moisture percentage by weight in the fuel. 584,Latent heat corresponding to partial pressure of water vapor, Kcal/kg.

What is washery grade coal?

Washery Grade – V. Exceeding 35% but not exceeding 42% Washery Grade -VI. Exceeding 42% but not exceeding 49% Grades of Semi-coking and Weakly Coking Coal.

What is difference between coking and non coking coal?

A coking coal is that coal which on heating in absence of air leaves a solid residue. A non-coking coal also leaves a solid coherent residue which may not possess the physical & chemical properties of the coke. … Coking coal are those coals which after heating in absence of air leaves a residual coke.

How do you calculate GCV?

The best equation has the following form: GCV= 25.284 (M) + 30.572 (Ash) + 62.127 (VM) + 138.117 (FC) – 2890.095. The result is in agree with previous work that equation involving four independent variables i.e. moisture (M), ash, volatile matter (VM) and fixed carbon (FC) provides the most accurate estimation of GCV.
