Patent number: 10151482Abstract: A system for controlling a gas burning appliance is disclosed. The system includes a central control unit. A pilot valve and main valve controls the flow of fuel from a fuel source to the pilot and main valve, respectively, and are configured for accepting an electrical current from a thermopile and from a power source. A spark generator generates for igniting fuel received by the pilot thereby generating a pilot flame. A flame sensor is adapted for monitoring the presence of a pilot flame. A thermopile proximate to the pilot burner is configured for generating an output electrical current for powering the pilot and main valve control devices. A relay routes electrical current between the power source and thermopile to the pilot and main valve control devices. A flame height regulating device conductively coupled with the power source is configured for adjusting a height of a main flame.Type: GrantFiled: June 24, 2015Date of Patent: December 11, 2018Assignee: DEXEN INDUSTRIES, INC.Inventors: Yu-Shan Teng, Peter Lee Cook

Publication number: 20090047610Abstract: A linearly regulated fuel valve system is provided that includes a slotted conical rotatable plug component that is received in a conical cavity formed in a valve body which can be remotely controlled. The slotted plug serves to establish multiple flow paths through the valve body when rotated so as to align an opening formed in the cavity wall with an orifice formed in the side of the plug. The rotational orientation of the plug with respect to the wall and the orifice in the plug is set by a latch element permitting graduated stepwise adjustment settings such as high, medium, low and shut off of gas flow through the valve. Accordingly, the unique system may be adjusted by remote controlled to a wide range of settings by a single cone having a constant channel for fuel flow.Type: ApplicationFiled: August 13, 2007Publication date: February 19, 2009Inventor: Yu-Shan Teng

Publication number: 20060204910Abstract: A unique control system is provided for fuel injection gas appliances to achieve efficient combustion by controlling the proportion of fuel and air variables. The combustion control system provides active feedback control of the combustion event and includes at least one detection sensor e.g. CO2 CO sensor and O2, to trigger the modulation of a gas valve to adjust pressure and gas flow to the combustion chamber of a gas appliance. A processor receives the concentration signal from the detection sensor to generate a proportionate control signal to modulate a pressure regulator of the gas valve thereby to control future combustion events to achieve maximum fuel combustion efficiency. Accordingly, the injection system varies the proportion of air to fuel inflow to a prescribed optimum range achieving efficient fuel combustion.Type: ApplicationFiled: March 14, 2005Publication date: September 14, 2006Inventor: Yu-Shan Teng

Publication number: 20060204911Abstract: A unique control system is provided for optimizing and effecting efficient combustion of gas appliances by controlling the proportion of fuel and air variables. The control system provides continuous active feedback of the combustion event by detecting the level of exhaust gases such as CO2 to trigger the modulation of a gas valve. Based upon the detected level, a control signal is generated by the system and received by a processor to adjust pressure and gas flow for future combustion events. Accordingly, the control system varies the proportion of air to fuel inflow to a prescribed optimum range thereby achieving efficient fuel combustion.Type: ApplicationFiled: January 12, 2006Publication date: September 14, 2006Inventor: Yu-Shan Teng
