Boilers have the most-flexible operations, but are most dependent on fuel costs.
Some other steam generator-related efficiency-improvement measures are worth considering: (1) the amount of excess air supplied to the combustor can be reduced to decrease the exergy losses with stack gases and (2) heat can be recovered from the spent combustion gases, before they exit the flue, to reduce fuel consumption.
A CHP unit typically consists of a prime mover, such as a gas turbine or piston engine, and a heat recovery steam generator, which is a type of boiler. The prime mover drives an electric generator and sometimes other equipment, such as air compressors. Its exhaust, via the steam generator, provides steam for heating or process use.
Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water then rises into the steam drum.
