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.

Dependent claims

A burner control mechanism comprising:

a processor;
a first mass flow sensor having a first port connectable to an air supply, and a signal terminal connected to the processor;
and
a second mass flow sensor having a first port connectable to the air supply, and having a signal terminal connected to the processor;
a first coupling point having a first port connected to the second port of the second mass flow sensor, having a second port and a third port;
a second coupling point having a first port connected to the second port of the first mass flow sensor, a second port connected to the third port of the first coupling point, and having third port connectable to a combustion chamber;
a shut-off device having a first port connected to the second port of the first coupling point and having a second port;
