Lower calorific value (lcv) or net calorific value (ncv), Biology

It is defined as the amount of heat liberated when one unit mass of fuel is burnt and the products of combustion are allowed to escape.

                                 LCV = HCV - latent heat of water vapour formed

Since, 1 part by mass of hydrogen gives 9 parties by mass of water

                                 LCV = HCV - (Mass of H2 in fuel * 9* latent heat of steam)

                                 LCV = HCV - (H * 9 * 587 kcal/kg.)

or                              LCV = HCV - (0.09 H * 587) KCAL/KG.

where, H is percentage of hydrogen in fuel.
