1. Examine the impact of feedwater heater pressure on cycle efficiency and determine the intermediate pressure for optimal performance for one heater. 2. Examine the financial implications of adding a feedwater heater(s) in relation to increasing plant efficiency, given that the installation of a single heater would cost 5% of the basic power plant's 0.8 x 106 $/MW total cost without heaters. One may calculate the cost of the additional heat energy to be added to the boiler at 0.02 $/MJ. Talk about how long it would take to recoup the expense of installing a single feedwater heater as well.
