4. An operating parameter often used by power plant engineers is the heat rate. The heat rate is
defined as,
HR
Qbioler
Wnet
where Qbioler is the heat transfer rate (Btu/h) to the water in the boiler due to the combustion of a
fuel and Wnet is the net power (kW) delivered by the plant. In comparison, the thermal efficiency
of the power plant is defined as,
nth
Wnet
Qbioler
where the numerator and denominator have the same units. Consider a power plant that is
delivering 1000 MW of power while utilizing a heat transfer rate of 3570 MW at the boiler.
Determine the heat rate and thermal efficiency of this power plant.
3. A steam power plant has an average monthly net power delivery of 740 MW over the course of
a year. This power delivery is accomplished by burning coal in the boiler. The coal has a heating
value of 9150 Btu/lbm. The cost of the coal is $14.20/ton. The overall thermal efficiency of the
plant is,
nth
Wnet
Qboiler
0.26 = 26%
Determine the annual cost of the coal required to deliver the given average monthly power.
