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: 10697815Abstract: Methods and systems for mitigating condensation in a sensor module of a combustion appliance are disclosed. In one example, a fluid flow from a main conduit is cooled with a passive heat exchanger. A sensor of a sensor module may be heated to a temperature above the cooled fluid flow. Cooling the incoming fluid flow with a passive heat exchanger and/or heating the downstream flow sensor may help mitigate condensation in the sensor module, and in particular, on the sensor device. This may help increase the reliability of the system.Type: GrantFiled: June 9, 2018Date of Patent: June 30, 2020Assignee: Honeywell International Inc.Inventors: David Kucera, Jos Praat, Hans van der Mei, Willem Super, Milos Trenz, Martin Bragg

Patent number: 10591161Abstract: Methods and systems for controlling a gas valve assembly and/or combustion appliance may include identifying a flow rate of gas to a burner of a combustion appliance and determining if the flow rate is sufficient for a burner load of the combustion appliance. If the flow rate is sufficient for a burner load, a position of the valve member of the valve assembly and/or the burner load may be adjusted such that the flow rate of gas meets a target flow rate of gas for the current burner load. If the flow rate is insufficient to meet the current burner load, the valve member of the valve assembly may be positioned in a fully open position to at least partially meet the current burner load. If the flow rate is below a minimum flow rate threshold, the valve member may be moved to a fully closed position.Type: GrantFiled: June 9, 2018Date of Patent: March 17, 2020Assignee: Honeywell International Inc.Inventors: Willem Super, Jos Praat, Hans van der Mei, Frank van Prooijen

Patent number: 10503181Abstract: The disclosure relates generally to pressure regulators, and more particularly, to pressure regulating valves. In one illustrative but non-limiting example, a pressure in a flow channel is translated into a position of a diaphragm, wherein the position of the diaphragm is dependent on the pressure in the flow channel. The position of the diaphragm is then sensed. A position of a valve in the flow channel is then controlled to adjust the pressure in the flow channel acting on the diaphragm so that the sensed position of the diaphragm is driven toward a predetermined position. This may result in regulated pressure in the fluid channel.Type: GrantFiled: January 13, 2016Date of Patent: December 10, 2019Assignee: Honeywell International Inc.Inventors: Gregory Young, David Kucera, Jos Praat, Donald J.

Patent number: 10422531Abstract: 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: May 19, 2017Date of Patent: September 24, 2019Assignee: Honeywell International Inc.Inventors: Willem Super, Frank van Prooijen, David Kucera, Sybrandus Munsterhuis, Jos Praat

Patent number: 10203049Abstract: This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.Type: GrantFiled: April 4, 2017Date of Patent: February 12, 2019Assignee: Honeywell International Inc.Inventors: David Kucera, Timothy McCarthy, Gregory Young, Donald J.

Patent number: 9841122Abstract: Valve assemblies may be configured to perform a valve proving test as part of an operational cycle of a combustion appliance coupled to the valve assembly. The valve assembly may include a valve body having a fluid path, first and second valves situated in the fluid path, first and second valve actuators, and a pressure sensor in fluid communication with an intermediate volume of the fluid path between the first and second valves. A valve controller may monitor a measure related to a pressure in the intermediate volume. The valve controller may then output a signal if the measure related to the pressure in the intermediate volume meets and/or exceeds a threshold value, where the threshold value is determined based on a measure related to an initial pressure in the intermediate volume and a known test duration.Type: GrantFiled: September 9, 2014Date of Patent: December 12, 2017Assignee: Honeywell International Inc.Inventors: David Kucera, Donald J.
