Introduction
What’s a Cogeneration/CHP System?
.Generation of multiple forms of energy in one system: heat and power
.Defined by its “prime movers”
-Reciprocating engines
-Combustion or gas turbines,
-Steam turbines
-Microturbines
-Fuel cells
Benefits of Cogeneration
.Increased efficiency of energy conversion and use
.Lower emissions, especially CO2
.Ability to use waste materials
.Large cost savings
.Opportunity to decentralize the electricity generation
.Promoting liberalization in energy markets
Type of Cogeneration Systems
Steam Turbine Cogeneration System
.Widely used in CHP applications
.Oldest prime mover technology
.Capacities: 50 kW to hundreds of MWs
.Thermodynamic cycle is the “Rankin cycle” that uses a boiler
.Most common types
. Back pressure steam turbine
. Extraction condensing steam turbine
