Cogeneration
Cogeneration or combined heat and power ( CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...

One possibility Abengoa Solar is assessing is the use of direct steam generation (DSG) inside parabolic troughs in order to achieve higher temperatures; in a first stage heating up to 450 °C and in a second stage heating up to 550 °C. For the future market potential of parabolic trough power plants with DSG, it is beneficial to integrate ...
Optimization of thermocline heat storage tank capacity for combined heat and power plant …
The extraction steam for heating is the exhaust steam from the intermediate-pressure cylinder, which heats the return water of the heat network from 60 C to 90 C through the heat network heater. At the cold end of the heat network heater, the exhaust steam
Combined cycle power plants
Cogeneration plants are also known as combined heat power (CHP) plants and are widely used in Europe where they provide steam heating as well as power to large city centers. Figure 1.4 is a photograph of this kind of plant where the steam is bled after the intermediate-pressure (IP) stage of a three-stage steam turbine, which consists of an HP …
