Boiler Efficiency and Combustion - beta.spiraxsarco.com

However, all common fuels contain hydrogen, which burns with oxygen to form water, which passes up the stack as steam. The gross calorific value of the fuel includes the energy used in evaporating this water. Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced.
