Re: High fuel consumption. The difference between GCV and NCV looks ok as the South African coal haveing about 4 to 5 % hydrogen. SO i feel there is no big differnce. e.g if coal having 4.5 % hydrogen then the heat taken by water for steam is ~ 236 Kcal/Kg, if South African coal of you specs (GCV=6206 Kcal/Kg) is taken for calculation purpose of NCV than deduct 236Kcal/Kg from GCV.

Calorific Value of Coal Fig 3 7/1: Difference: GCV vs. UHV Comparison: GCV vs.UHV Grade System 8000.00 The combustible material in coal remains unchanged right from the point of release (mines/stockyard/purchase point) to the point of consumption (power plant/steel plant/cement plant etc) except for Total Moisture (TM) %.
The difference being the latent heat of condensation of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed.

The NCV values of coal are derived from experimentally determined Gross Calorific Value (GCV) and the available hydrogen content of coal using the formula, : (2) NCV = GCV-53 H where H is the available hydrogen content of coal which accounts for the total hydrogen including those associated with the moisture.
The test is carried out on air dried sample and is calculated to as received and dry basis. Net Calorific is a calculation on the heat value which encompasses GCV, total moisture, hydrogen, nitrogen and oxygen. The main difference between GCV & NCV according to ISO 1823 is related to the physical state of water in the reactive product.
Answer (1 of 4): Best Answer: GCV (gross calorific value) is the quantity of heat produced by combustion when the water produced by combustion is allowed to return to the liquid state.

The absorptive power or calorific power is the product of the volumic flow rate of gas by the NCV with constant pressure of fuel expressed in quantity of heat. Qv = Volumic flow rate of gas. PCI = Lower calorific value of gas. Last update: 10/13/2021 14:05:50.
NCV vs. GCV. Some statistical offices use gross calorific values (GCV) The difference between NCV and GCV is the latent heat of vaporisation of the water produced during combustion of the fuel: for coal and oil, the NCV is about 5 % less than the GCV. for most natural and manufactured gas, the NCV is about 10 % less .
