Combined Heat and Power – Technologies - GOV.UK

A CHP plant consists essentially of an electrical generator combined with equipment for recovering and using the heat produced by that generator. The generator may be a prime mover such as a gas turbine or a reciprocating engine. Alternatively, it may consist of a steam turbine generating power from high- pressure steam produced in a boiler.

Boiler Combustion - CleanBoiler.org

Excess Air. 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.
