Power Plant Efficiency: Problems and Analysis

Analysis of a Condenser Problem Given a set of conditions describe how changes in related parameters can be used to identify the cause of a decrease in condenser vacuum. Describe how a problem that causes condenser vacuum to decrease affects unit heat rate and fuel consumption. Analysis of a Boiler Problem Given a set of conditions describe how changes in related parameters can be used to identify the cause of an increase in boiler exit gas temperature. Describe how a problem that causes boiler exit gas temperature to increase affects unit heat rate and fuel consumption. Analysis of a Feedwater Heater Problem Given a set of conditions describe how changes in related parameters can be used to identify the cause of a decrease in final feedwater heater outlet temperature. Describe how a problem that causes final feedwater heater outlet temperature to decrease affects heat rate and fuel consumption.
