To meet various environmental regulations, it is often necessary to utilize design features that will greatly increase the cost of the power plant without increasing its efficiency. For example, the cost of the pollution control equipment that will be required for each site under consideration is one such item which must be carefully evaluated. |

Diesel engine -driven electric generator sets are divided into three general categories based on application as follows: - Class A: generator sets for stationary power plants generating prime power continuously at full nameplate kw rating as the sole source of electric power
- Class B: generator sets for stationary power plants generating power on a standby basis for extended periods of time where months of continuous operation at full nameplate kw rating are anticipated.
- Class C: generator sets for stationary power plants generating power on an emergency basis for short periods of time at full nameplate kw rating where days of continuous operation are anticipated. |

In general combined cycle power plant is the combination of gas turbine generator (Brayton cycle) with turbine exhaust waste heat boiler and steam turbine generator (Rankin cycle) for the production of electric power. If the steam from the waste heat boiler is used for process or space heating, the term “co-generation” is the more correct terminology (simultaneous production of electric and heat energy) |
