An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.

A water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively run only the pilot for at least part of a heating cycle to increase the recharge time of the rechargeable power storage device while still heating the water in the water heater.

A water heater control system comprising an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The energy storage system may be electrically connected to an ignition circuit. A thermoelectric device is in thermal communication with the pilot flame and electrically connected to a main valve operator. The water heater system may include a microcontroller configured to establish electrical communications between the device and the energy storage system, the pilot valve operator, and the main valve operator. The microcontroller may be configured to recognize a call for main burner operation, and may also be configured to check an available voltage of the energy storage system against a setpoint. The microcontroller may establish pilot flame operation with or without main burner operation, depending on whether a call for heat or recharging of the energy storage system is required.

Provided are embodiments of a gas valve for an intermittent pilot ignition system. The gas valve includes features designed to address the buildup of negative pressure in a fuel line connected to the gas valve that could cause internal valve diaphragms to open, drawing fuel from the gas valve. In embodiments, the gas valve includes a system of check valves designed to seal off the gas valve when a negative pressure develops. In other embodiments, the gas valve includes a relief valve having a relief port so that air is able to enter the valve proximate to the inlet port so as to avoid building a negative pressure sufficient to open the diaphragms. In both cases, the valve remains primed with fuel for subsequent ignition. The gas valve is envisioned to be useful for a variety of pilot operated systems.

A method of controlling water heater pilot flame ignition includes receiving, by a controller of a water heater, a user input and controlling a pilot gas valve to start a gas flow to a pilot burner in response to the user input. The method further includes, in response to the user input, controlling, by the controller, an igniter to generate an ignition spark for lighting a pilot flame. The method also includes controlling, by the controller, the pilot gas valve to maintain the gas flow to the pilot burner if the pilot flame is lit.

The present invention provides a gas valve and a control device and a control method thereof wherein the control device receives a detection voltage generated by a thermocouple. the control device outputs the second voltage when the detection voltage generated is greater than a predetermined voltage, and then outputs the first voltage. The control device stops outputting the first voltage when receiving a shut-off signal, and the control device starts counting time and stops outputting the second voltage when the time counted reaches a predetermined time.

The present invention discloses an outdoor gas heater, comprising an outer cover, an outer cover side baffle, a gas injection pipe, a ceramic burner, a body box, a control box connecting support frame, a control box sealing plate, a control box, a wall-mounted bracket and a long open a flame connecting pipe. Four ceramic burners are fixed side by side in the body box, a gas injection pipe is fixed on the lower side of the body box, and a gas injection pipe is sealingly connected to the four ceramic burners; the outer open end of the body box is locked to the outer cover, and the side of the body box opposite to the outer opening thereof is locked to the control box connecting support frame. The control box connecting support frame is a U-shaped structure, and side wall of which is locked on both sides of the control box, and the outer side opening of the control box is locked to the control box sealing plate; the side of the control box opposite to the outer opening is locked to the wall-mounted bracket. The structure is reasonable in design and convenient to use, and its installation and use is very convenient and safety is greatly improved; moreover, it can save energy and maintain the demand for power supply for a long time.

A heater structure includes a heater body including a burner connected to a valve switch. A pilot fire assembly is covered by a protective cover that has ventilation holes. A switch unit includes an ignition switch, a shut-down switch, an ignition operator, and a shut-down operator. The ignition operator and the shut-down operator are structured to provide a swingable arrangement. The ignition operator may be operated to contact and press the fuel gas valve rod and the ignition switch to open the valve switch for supply fuel gas to the burner and to activate an ignition circuit to cause successive shootings of an ignition pin of the pilot fire assembly to set a flame on the burner. The shut-down operator is operated to contact and press the shut-down switch, so as to cut off a signal of the thermocouple and thus cut off the supply of the fuel gas.
