What is the difference between GCV and UHV of coal?
What is the difference between GCV and UHV? While in UHV ( useful heat value) it is assumed that those elements cant produce heat and so are eleminated for the purpose of heat calculation. So as result of it the heat value by UHV falls on conservative side compared to GCV and so UHV is not good for supplier.
How to Calculate a Calorific Value | Calorific Value Unit
We refer to it as the gcv of the fuel. We can subtract from the hcv, an amount of heat required to evaporate the water formed, we can easily find Lower Calorific Value (LCV). Besides, we also know it as Net Calorific Value (LCV) i.e. Net Calorific Value of the fuel.
