2 Cogeneration Process Heat Pump Boiler Process Heater Thermal energy that is required by some industries. Process heat is usually supplied by steam at 5-7 atm and 150-200 ºC. Industries that use large amount of process heat also consume a large amount of electric power.

3 Cogeneration Cogeneration is the production of more than one useful form of energy from the same energy source. Turbine Pump Boiler Process Heater

4 Cogeneration Optimum Condition 1 2 3 7 4 5 6 8 Condenser Turbine P 1 P 2 Boiler Process Heater Expansion Valve m 4 = m 6 m 5 = m 7 = 0

5 Cogeneration No Load 1 2 3 7 4 5 6 8 Condenser Turbine P 1 P 2 Boiler Process Heater Expansion Valve m 5 = m 6 = 0

6 Cogeneration Peak Load 1 2 3 7 4 5 6 8 Condenser Turbine P 1 P 2 Boiler Process Heater Expansion Valve m 4 = m 5
