Consider a reheat regenerative steam cycle with a single open feed-water heater (i.e. a deaerator) for a CSP (concentrating solar power) plant that generates a gross steam turbine output of 11 MW. The boiler comprises an economizer (ECO), evaporator (VAP), superheater (SH) and reheater (RH). Steam at 95 bar and 500C enters the HP (high pressure) turbine while the reheat steam at 15 bar and 420C enters the LP (low pressure) turbine. Steam is extracted from the 'cold reheat' at 15 bar and throttled to 10 bar for use in the deaerator. The condenser (COND) pressure is 0.05 bar. The efficiencies of the high pressure (HP) and the low pressure (LP) turbines are 85% and 90%, respectively. The overall boiler efficiency is 96% while the efficiencies of the pumps (P1 and P2) are both 80%. SH RH VAP ECO HP LP 10 Mondeser mot PI 3 mregeneration DEAERATOR + P2 COND Illustrate the cycle on a temperature-entropy (T-s) diagram identifying all the state points. Prepare a "heat and mass balance diagram" for the steam cycle and hence determine the steam cycle heat rate, the total heat required from the CSP panels and the resultant overall power plant electric heat rate [Max 1 answer book].
