Exemplary embodiments of a system and method for bimodal air control in a kettle-style grill are configured to be detachably mounted to the exterior of a kettle-styled grill such as, but not limited to, a Weber charcoal grill. When mounted to the kettle-styled grill, a plenum-like component directs air flows to the interior of the grill's kettle via the kettle's lower body damper holes. A manually adjustable intake damper in the plenum component allows, restricts, or prevents a drawn ambient air flow into the plenum component. Separately, a forced air flow generated by a fan may also be provided into the plenum component. Adjustment of the intake damper may also adjust damper blades inside the grill's kettle. Ash that falls out of the kettle's damper holes falls through the plenum component and is captured in an ash receptacle that is removably mounted to the plenum component.

A combustion air proving (CAP) system for a burner assembly having a burner for providing heated air to a location, a controller, and a back plate, where outside air is fed to the burner via a conduit. The CAP system is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

A gas supply system for a flame module of a spectrometer and a method of controlling a flame module. The gas supply system comprises an oxidant gas supply line for providing a supply of oxidant gas, an oxidant gas flow valve for varying a gas flow rate of an oxidant gas in the oxidant gas supply line, an oxidant gas safety controller configured to control the oxidant gas flow valve, a fuel gas supply line for providing a supply of fuel gas, a fuel gas flow valve configured to control a gas flow rate of a fuel gas on the fuel gas supply line, and a fuel gas safety controller configured to control the fuel gas flow valve. During normal operation, the oxidant gas safety controller is configured to charge an energy storage circuit of the oxidant gas safety controller. In the event of a power failure, a first switch of the oxidant gas safety controller is configured to connect the energy storage circuit to the oxidant gas flow valve, wherein the energy storage circuit is configured to discharge energy to the oxidant gas flow valve to increase the oxidant gas flow rate in order to extinguish a flame of the flame module, and the fuel gas safety controller is configured to close the fuel gas flow valve.

A wood stove monitoring and control device can include a mounting flange mountable to a chimney exhaust pipe of a wood stove. The device can include a ring removably mountable on top of the mounting flange, where the flange is suitably positioned vertically along the exhaust pipe so that the ring is positioned at least partially above an end of the exhaust pipe. The device includes an optical beam source disposed on the ring, and which generates and outputs an optical beam. The device includes an optical sensor positioned on the ring opposite the optical beam source to detect the optical beam output by the optical beam source as the optical beam passes through smoke exhausted by the wood stove through the exhaust pipe. The device can include a temperature probe disposed on the ring to measure a temperature of heat exhausted by the wood stove through the exhaust pipe.

A control system for a fuel-burning appliance such as a wood or pellet burning stove may include a particulate matter sensor. The control system may also include an ignition system to ignite an ignition charge of ignitable fuel. A processor controls the operation of the functional components of the appliance to maintain operating conditions within pre-determined parameters.

A method for regulating a wood burner that burns wood pellets. For a batch of pellets the method includes, determining the air flowrate and fuel flowrate parameters according to the levels of combustion of the pellets in a defined pellet-fired burner, creating at least one curve, identifying the optimal air and fuel parameters, recording these optimal parameters, the type of burner, the batch number, possibly extrapolating to other pellet-fired burners, recording these extrapolated optimal parameters, labelling each bag with information relating to these optimal parameters, when using a bag of pellets in a domestic pellet-fired burner, reading the information using reading means, and regulating the domestic burner by acting on regulating means that regulate the supply of air and fuel to the burner.

A boiler comprising an enclosure which forms a heating chamber which contains water to be heated and accommodates a firebox which forms a combustion chamber with a burner associated therewith which comprises a combustion head, arranged in the combustion chamber and connected to a supply duct, and provided with a premixer of combustion air and combustible gas which is interposed along the supply duct. The combustion chamber is connected to a stack for the evacuation of the combustion gases into the external environment, elements being further provided for generating a flow of a mixture of air and gas toward the combustion head; at least one duct being provided for conveying the combustion gases which connects the stack to the supply duct.

An apparatus and method for reclaiming uncondensed hydrocarbons normally exhausted to the atmosphere from a still column of a glycol dehydrator system, and combusting the uncondensed hydrocarbons in a burner assembly of a reboiler after the burner assembly has been ignited by fuel gas.

A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

The disclosed technology includes a device for extending the turndown ratio of a gas-fired burner system. The device can comprise a variable area device configured reduce the amount of fuel and air passed to the burner during low output conditions by adjusting the cross-sectional area of the passage between the blower and the burner. The variable area device can be controlled by an actuator that adjusts the position of the variable area device. The actuator can be manually controlled, mechanically controlled, or electronically controlled.
