Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency can be calculated using ASME Performance Test Codes (PTC). PTC 34 is used for waste combustors with energy recovery using the boiler as a calorimeter. Using this method, the heat outputs, losses and credits must be calculated. Heat credits correct the efficiency to standard ambient conditions, such as air temperature.

Boiler - Wikipedia

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.
