System for controlling combustion in a gas combustion-type turbine
 An improved combustion system that is constructed and arranged to be used with a power-generating turbine or the like includes at least one combustion chamber, a fuel supply system for supplying fuel to the combustion chamber, an air supply system for supplying air from a pressurized air source to the combustion chamber, a monitor for monitoring a property of the combustion products from the combustion chamber, a regulator for regulating an air to fuel ratio in the combustion chamber, and a controller, in communication with the monitor and the regulator for controlling the regulator in response to information received from the monitor. According to one novel aspect of the invention, the controller controls the regulator with no direct mechanical linkage therebetween, so that the complexity and expense of the system is kept to a minimum.
