Apparatus and method of automatic NOx control for a gas turbine. |
摘要 |
A gas turbine power plant has coolant injected into the combustors in order to reduce the level of nitrogen oxide produced by the combustion of natural gas fuel and/or oil. A control system controls injection of coolant into the combustors in order to reduce NOx emissions, while improving turbine cycle efficiency and avoiding the possibility of over-injection of coolant to the point of flame-out in the combustor. PID controllers are used to provide percentage error bias in the control system, whereby adjustment of coolant injection follows turbine load in a manner that increases turbine efficiency. <IMAGE> |
