Thermodynamic Analysis of a Combined Heat and Power Unit Using Extractions A2, A3 and Crossoverpipe IP–LP for Heater Supply



This chapter presents thermodynamic analysis of the a electric power unit with the rated capacity of 370 MW operating in cogeneration under the assumption of multitude of alternatives of heaters being fed from extractions A2 and A3 of the low-pressure section of the steam turbine and LP–IP crossoverpipe. This analysis takes into consideration feeding heaters from a single and two power units. In addition, the calculations involve a case when the power unit is restored to its original capacity prior to adaptation to cogeneration and one without compensation.
