    摘要： A specialized miniature housing installable between a source of gas and gas burners provides an aftermarket safety system for a gas grill. The system prevents accidental accumulation of gas in an enclosed volume within or around an unignited grill, thereby reducing or eliminating the risk of explosion. The housing includes a microcontroller coupled to an internal flow sensor, an external temperature sensor, and a valve. In response to signals received from the sensors, the microcontroller commands the valve to remain open only when positive flow through the housing is coincident with sufficient temperature at the burners. Otherwise, or upon loss of power, the valve closes to cut off gas supply to the grill.

    摘要： A method for operating a premix gas burner wherein an air flow rate and/or a fuel gas flow rate are controlled so as to generate heat with the premix burner in accordance with a heat demand related value. The fuel gas comprises hydrogen and the method further provides a desired air excess factor relation of the air/fuel gas mixture which defines the relation between a desired air excess factor and an input variable like the heat demand related value, an air flow rate related value, or a fuel gas flow rate related value. The desired air excess factor is not a constant factor but varies for different input variable values. The fuel gas flow rate and/or the air flow rate are controlled such that an actual air excess factor converges towards the desired air excess factor while meeting the heat demand.

    摘要： A method is provided for controlling combustion in a modulating gas furnace. The method includes receiving an indication of a firing rate setpoint for a burner assembly, and applying the firing rate setpoint to first and second continuous functions that map the firing rate setpoint to air-to-fuel ratio and combustion system pressure setpoints. A variable-speed draft inducer blower is set to drive to a combustion system pressure setpoint, and the modulating gas valve is controlled during combustion in the combustion system. In this regard, a combustion system pressure measurement is obtained and applied to an inverse of the first continuous function that outputs an adjusted firing rate for the combustion system pressure measurement. The adjusted firing rate is applied to a third continuous function that maps the firing rate to gas valve position, and outputs a gas valve position to which the modulating gas valve is set.
