Open the CIPO recordAbstract From the Canadian patent
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 overinjection 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.

Why it's free to use
- Filed September 14, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 14, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 14, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
