Use of Condensers in Thermal (Steam) Power Plants

In CHP configuration, there is no condenser and the steam and condensate, after exiting the process, is returned to the boiler. There are numerous options in the steam supply, pressure, temperature and extent, if any, for reheating steam that has been partially expanded from high pressure. Steam systems vary from low pressure lines

correlation with the steam operating pressure. As pressures increase, the temperature is higher. When the latent heat of steam is removed, the condensate will be close to the saturation temperature corresponding to the steam pressure in the heat exchanger shell. Slight sub-cooling of the condensate will occur before exiting from the shell.
