CHP Technological Advances
Packaged CHP Systems
According to the DOE, "packaged CHP systems" integrated into commercial buildings can offer up to a 30-40 percent improvement in building efficiency over today's best practices. CHP component manufacturers and DOE are developing pre-engineered, modular CHP systems to make it easier for building owners to connect CHP systems to power, piping, or ducting systems.
Heat Recovery Steam Generator (HRSG)
The waste heat generated by a combustion turbine can be used to generate steam in a heat recovery steam generator (HRSG), which can power a steam turbine, heat living space, or generate cooling using steam-driven chillers. The advantages of these types of systems are inexpensive electrical power and better reliability since the user may be independent from the grid. These systems can be started even if the grid has failed.
