Auxiliary Boiler Sample Clauses | Law Insider
The auxiliary boiler provides steam until the HRSG begins providing steam and sparging steam upon plant shutdown. During initial start-up (i.e. with no cold reheat or HP steam available), auxiliary steam will be provided by the auxiliary boiler at 125 psig saturated. The auxiliary boiler is fired by natural gas from the Fuel Gas System.

Boiler Combustion - CleanBoiler.org
A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
