Patent number: 11421875Abstract: A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.Type: GrantFiled: August 22, 2019Date of Patent: August 23, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Gregory Young, David Kucera, Donald J. Kasprzyk, Willem Super, Jos Praat, Roelof Thiewes, Hans M. van der Mei, Brian Zabel, John D. Mitchell

Patent number: 11149946Abstract: 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.Type: GrantFiled: June 10, 2019Date of Patent: October 19, 2021Assignee: Honeywell International Inc.Inventors: Willem Super, Peter Vermass, Hans M. van der Mei, Roelof Thiewes, Donald J.
