A method of improving an endothermic process in a furnace utilizing steps a) calibrating the simplified physical model of step c3) by measuring one or more tube temperature for at least a tube impacted by the throttling of a burner in standard and in throttled state, b) acquiring information on a tube temperature for the tubes present in the furnace with all the burners present in the furnace under standard non-throttled conditions, c) getting a map of burners to throttle including c1) choosing at least one parameter representative of the performances of the furnace with a target of improvement, c2) choosing at least one or more power ratio for the burner throttling, c3) utilizing the information of step b) and a simplified physical model of the impact of throttling a burner on the tube temperature, c4) getting a map of burners to throttle, step d) throttling the burners.

Actuation of timed combustion events that may be emitted from an edifice. A system includes a mobile edifice, a controller, a fuel source comprising a fuel, and a combustion device mounted to the mobile edifice. The combustion device includes a heat source in electronic communication with the controller, and a gate in electronic communication with the controller. The system is such that the gate opens to permit fuel to flow from the fuel source to toward the heat source, and such that the controller actuates the heat source and the gate to trigger a combustion event.

Various embodiments of the teachings herein include a mixer disposed in a fuel gas combustion system and mixing air and fuel gas to form flammable mixed gases. The mixer may include: a Venturi tube having an air inlet, a fuel gas inlet, a gas mixture outlet, a central axis direction, and a throat positioned between the air inlet and the gas mixture outlet in the central axis direction, wherein the fuel gas inlet is disposed at the throat; and an adjustment component disposed in the Venturi tube downstream of the throat, the adjustment component drivable to move towards or away from the throat in the central axis direction, thereby changing a flow area of gas in the Venturi tube. The adjustment component comprises a conical valve plug with a conical outer surface thereof at a side facing towards the throat and fitting an inner surface of the Venturi tube.

The object of the present invention is a control method for verifying the presence of the flame in the combustion chamber (41) of a premixed gas burner (1), fed by an air and gas mixture mainly and/or essentially comprising hydrogen H2. The method is based on the use of at least one temperature sensor (6), the values whereof are sent to a control device (8) which uses them to calculate the derivative T over time of the temperature T to compare it to suitable feedback thresholds (Tau1, Tau2; Tau3, Tau4) to establish the ignition occurred, the ignition failure or flame extinguishment.

A furnace heating device comprising one or more radiant tubes that are configured in one or more zones of a furnace chamber; one or more burners that are coupled to the one or more radiant tubes and one or more burner control units; a programmable controller that is configured to determine one or more estimated radiant tube temperatures that respectively correspond to the one or more radiant tubes, generate one or more control signals based on the one or more estimated radiant tube temperatures with respect to a threshold temperature, wherein the one or more control signals instruct the one or more burners to operate in a flame combustion operation or a flameless combustion operation, and provide the one or more control signals to the one or more burner control units to enable flameless combustion at furnace chamber temperatures that are below a minimum temperature for flameless combustion.
