Calorific Value or Heating Value of the Fuel & …

So the change in the moisture content changes the proportion of the other coal constituents and the Calorific Value. ‘As Received’ coal, is the coal received in the power plant premises. The payment to the coal companies are normally made based on the ‘As Received’ coal properties. ‘As Fired’ coal is the coal entering the boiler system.

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Gross Calorific Value - an overview | ScienceDirect …

Calorific value is the heat energy released per unit mass of fuel burned as shown by Formula F7.1. Gross calorific value, or higher heating value (HHV), is the total heat released making no allowance for the latent heat required to vaporize the liquid water produced by the combustion process.Hence it is a theoretical parameter and is rarely used. The net calorific value, or lower heating value
