Boiler startup test and ensuring peak efficiency
Boiler startup test and ensuring peak efficiency
(OP)
Hi,
During a boiler startup, (hot water heating boiler,condenser boiler) the specs call for adjusting boiler to ensure peak efficiency, how is this done?
Tests are performed at 100% load, 75% load, 50% load, and 25% load, what kind of tests are usually performed?
Thanks for all replies, appreciate your comments.

I apologize,the above sentence should say the following:
the specs call for adjusting boiler "BURNER" to ensure peak efficiency, how is this done?
Thanks.

Typically you want to minimize the O2 in the flue gas stream, maximize the CO2, while trying to have no CO.
Also typically, you don't completely eliminate the O2 from the flue gas stream, because if you do, you are operating with too tight a margin for changes in other variables that affect burner performance; atmospheric pressure and temperature of combustion air, as well as variations in the fuel.
So you get it as tight (low O2, high CO2, trace or no CO) as you can and strike a happy medium so that you can obtain decent values for all 4 points that you gave.
