Gross Calorific Value
The gross calorific value (GCV) of dry bagasse has a mean value of 19605 kJ/kg. The gross calorific value (GCV) of wet bagasse is based on the composition of wet bagasse. Water has no calorific value and it also absorbs heat being vaporized during combustion. The combustion reactions of bagasse as a fuel are as given in Table 3 ( Mugadhi 1999 ...

How to Calculate the Coal Quantity Used in a Power Plant
We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit. The cost of fuel is the main factor in the cost of a unit of electricity.

What is the difference between Gross Calorific Value and Net
It is also known as Higher Heating Value (HCV). Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H20 formed as a vapor. Natural gas prices are decided on the basis of GCV …
