power plants have been constructed in the last decade.1 Figure 1-1 illustrates the various components of a power plant and factors that affect its thermal efficiency. Operating experience reflects that the thermal efficiency of a power plant declines with use. Much of the efficiency degradation can be recovered during maintenance outages
Natural gas power plants generate electricity by burning natural gas as their fuel.There are many types of natural gas power plants which all generate electricity, but serve different purposes. All natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.
