Steam Boilers, Engines, Nozzles and Turbines Heating value of fuel used is as on fired basis. If it is reported for dry or moisture free fuel, then latter should be multiplied by the following factor to correct for as fired value 1 + moisture content (1 + moisture content) 1 – moisture content (1- moisture content) 1 + moisture content (1 + moisture content) 1 – moisture content (1- moisture content) ANSWER DOWNLOAD EXAMIANS APP
