preparation of coal to determine calorific value

Calorific Value or Heating Value of the Fuel & Moisture

Coal is the primary fuel for producing Electricity. Some of the characteristics of coal have profound influence on the day to day working and economics of the power plant. This article discusses Calorific Value and Moisture. Calorific value is the most important parameter that determines the economics of the power plant operation.

Calorific Value an overview | ScienceDirect Topics

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.

Preparation of a biochar with a high calorific value from

The calorific value is higher than the first-level cleaned coal of 30.00 MJ/Kg, indicating a good practical value. Due to its pore structure and high fixed carbon content, biochar of chestnut shells has a higher calorific value than the raw material and first-level cleaned coal.
