This program calculates boiler efficiency using the heat loss method of  the ASME Boiler Code PTC-4.1. The program accepts the ultimate analysis of any fuel,  % by weight for liquids and % by volume for gases. It performs a stochiometric analysis of the combustion and calculates the individual losses, the quantities and types of gases produced, and the air flow required for the given % excess air.
