Calorific Value Of Oil Fuel Boiler


Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.

Net calorific value, gross calorific value and

The gross calorific value (H o or H s) is the energy released during a complete combustion when the flue gas is cooled back to the reference temperature at a constant pressure and the entire quantity of water produced is condensed. The gross calorific value therefore also contains the condensation heat, also referred to as "latent heat".
