摘要： A method includes firing a first burner into a furnace process chamber in a first initial condition, firing a second burner into the process chamber in a second initial condition, and measuring temperature at each of an array of locations in the process chamber. The first burner is adjusted to a first adjusted condition while the second burner is being fired at the second initial condition, and a resulting first temperature change is measured at each of the locations. The second burner is adjusted to a second adjusted condition while the first burner is being fired at the first initial condition, and a resulting second temperature change is measured at each of the locations. The measured first and second temperature changes are recorded as reference data for adjusting burner conditions to adjust temperatures at each of the locations. The method can thus be used to improve temperature uniformity throughout the array of locations.

摘要： A cooking appliance that includes: a gas cooking element; an igniter located next to the gas cooking element to ignite the gas cooking element; a gas valve for regulating gas flow to the gas cooking element; a burner control coupled to the gas valve to vary the gas flow to the gas cooking element; and a control circuit coupled to the burner control and for activating the igniter when the burner control is positioned within a predetermined range of positions, where the control circuit detects when the burner control has been moved through the predetermined range of positions in less than a predetermined time, and in response to determining that the burner control has been moved through the predetermined range of positions in less than the predetermined time, generate an alert to a user.
