ABSTRACT:
A flow controller system for optimally controlling the flow of air and fuel to a burner in a plurality of operating modes throughout the firing range of the burner is disclosed herein. The system includes a pair of differential pressure sensors connected across the air conduit and the burner, and the fuel conduit and the burner, as well as a pair of electrically operated air and fuel valves for controlling the pressure of the air and fuel destined for the burner. The system further includes a microprocessor control means electrically connected to both the pressure sensors and the air and fuel pressure regulating valves. Optimal air-to-fuel pressure ratios are empirically derived at each point along the firing range of the burner by means of detachably connectable flowmeters, oxygen sensors and thermocouples, and this information is stored within the memory of the microprocessor control means. The use of a microprocessor control means, in combination with a detachably connectable flowmeter and thermocouple, allows the system to be easily retrofitted onto an existing burner system without the need for installation of orifice plate-type flowmeters.
