· HHV vs LHV - GCV vs NCV Explaining the conventions for quantifying the heat of combustion. 3 minute read A British engineer argues with a European engineer about what to assume for a gas boiler efficiency. The European engineer demands they assume 89% – the British engineer disagrees and wants to assume 80%. Who is correct?

15-10-2022 · The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal.
