US 10,422,531 B2 · System and approach for controlling a combustion chamber

Abstract

A system for controlling activity in a combustion chamber. The system does not necessarily need to be mechanically adjusted and yet may provide precise control of a fuel air mixture ratio. A sensing module of the system may have a mass flow sensor that relates to air flow and another sensor that relates to fuel flow. Neither sensor may need contact with fuel. Fuel and air to the system may be controlled. Pressure of the fuel and/or air may be regulated. The sensors may provide signals to a processor to indicate a state of the fuel and air in the system. The processor, with reliance on a programmed curve, table or the like, often based on data, in a storage memory, may regulate the flow or pressure of the fuel and air in a parallel fashion to provide an appropriate fuel-air mixture to the combustion chamber.

A burner control system comprising:

a first flow path having an input from an air supply;
a second flow path having an input from the air supply and a fuel supply;
a third flow path having a first arrangement with an input only from the air supply and a second arrangement with an input from the air supply and the fuel supply;
a sensor in communication with the third flow path;
a processor in communication with the sensor, wherein the processor is configured to selectively configure the third flow path in the first arrangement such that the sensor senses a measure indicative of a measure in the first flow path and selectively configure the third flow path in the second arrangement such that the sensor senses a measure indicative of a measure in the second flow path;
a sensor in communication with the first flow path;
and a sensor in communication with the second flow path.
