FUELS HIGHER CALORIFIC VALUES

FUELS HIGHER CALORIFIC VALUES 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). The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat

Moisture Correction for Coal Analysis

Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.

What are NCV and GCV of a fuel and why NCV

 · NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion remains gaseous. Since water releases heat when it condenses, GCV is clearly bigger than NCV. GCV is also called HHV (higher heating value); NCV is also called LHV (lower heating value.)
