: Using the heat loss method you can calculate the boiler efficiency but you will not need steam flow, however, you will need more information than what you listed.
: You will need:
: the steam pressure and temperature,
: the feedwater temperature and pressure,
: combustion air temperature,
: O2 leaving the boiler,
: Flue gas leaving the boiler,
: Fuel analysis,
: This test method is available as part of PTC 4.1 through ASME.
:
: : How can you calculate approx. efficiency when you only know steam flow water flow and exhaust gas temp?
