A system for electronically controlling a vent damper for a gas oven.

A system and process for intermittently venting combustible gas (c-gas) from a continuous source to the atmosphere are presented. The system may include a c-gas storage tank, an admission valve located upstream of the c-gas storage tank for regulating the flow of c-gas from the continuous source to the storage tank; an inert gas storage tank and an inert gas valve for regulating flow of inert gas to the c-gas storage tank, the inert gas diluting the c-gas within the c-gas storage tank below a flammable level; a vent valve for atmospheric venting located downstream of the c-gas storage tank, and a PIC that opens the vent valve when pressure in the c-gas storage tank reaches a pre-determined PIC vent point. The system may also include an auxiliary system to receive and vent c-gas diluted below the flammable level while the primary admission valve is closed.

A water heater monitoring and notification method includes determining, by a controller of a water heater system, a deviation of a duration of a pre-purge operation from a pre-purge duration average value. The method further includes determining, by the controller of the water heater system, a deviation of a flame current from a flame current average value and determining, by the controller of the water heater system, a deviation of a pulse-width-modulation (PWM) parameter from a PWM parameter average value. The method also includes providing a notification related to a combustion system of the water heater system based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, and the deviation of the PWM parameter from the PWM parameter average value.

A controller monitors temperature in a bio-fuel fired device and automatically controls dampers, blowers and the like to reduce generation of smoke or other pollutants, thereby promoting proper operation of a catalytic converter.

A flame analytics system that may incorporate a burner, one or more sensors at the burner, a historical database connected to the one or more sensors, a model training module connected to the historical database, and a runtime algorithm module connected to the one or more sensors and the model training module. The runtime algorithm may compare realtime data from the one or more sensors and historical data from the model training module in accordance with a machine learning algorithm. The system may further incorporate a fault detection module connected to the runtime algorithm module, a fault diagnostics module connected to the fault detection module, and an enunciator connected to the fault detection module.

A system that includes: a gas turbine having a combustion system; a control system operably connected to the gas turbine for controlling an operation thereof; and a combustion auto-tuner, which is communicatively linked to the control system, that includes an optimization system having an empirical model of the combustion system and an optimizer; sensors configured to measure the inputs and outputs of the combustion system; a hardware processor; and machine-readable storage medium on which is stored instructions that cause the hardware processor to execute a tuning process for tuning the operation of the combustion system. The tuning process includes the steps of: receiving current measurements from the sensors for the inputs and outputs; given the current measurements received from the sensors, using the optimization system to calculate an optimized control solution for the combustion system; and communicating the optimized control solution to the control system.

An alert sensing stove assembly includes a stove that includes a plurality of burners. A plurality of valves is provided and each of the valves is in fluid communication with an associated one of the burners. A processor is coupled to the stove and the processor is electrically coupled to each of the valves. A sensor array is coupled to the stove to detect a variety of alert agents. The processor sends a shut down signal to each of the valves when the sensor array detects one of the alert agents. Thus, the sensor array enhances safety with respect to unattended operation of the stove. A communication unit is provided and the communication unit is coupled to the stove. The communication unit transmits an alert signal to an extrinsic communication network when the processor sends the shut off signal to alert a user to a potentially dangerous situation.

An automatic pilot lighting system for unattended automatic lighting of a standing pilot may include a powered (e.g., battery powered, etc.) circuit. The powered circuit may include an analog timer circuit including a timer switch. A spark ignitor may be coupled with the timer switch. A temperature knob pilot momentary switch may be coupled with the timer switch. An ON/OFF switch may be coupled with the temperature knob pilot momentary switch and the timer switch.

The analog timer circuit may be configured to be selectively activatable for applying voltage from the power source via the ON/OFF switch for pilot hold voltage and spark ignition for an amount of time sufficient to allow for unattended automatic lighting of the standing pilot and sufficient voltage generation to support standalone operation.

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.
