摘要： An apparatus includes a burner, a first conductive element positioned across the face of the burner, a second conductive element positioned within the flame from the burner, and positive and negative electrodes coupled with a power source. The positive electrode and the negative electrode are configured to generate an electric field between the first and second conductive elements affecting the flame, and the electric field is operable to form at least one flame root defined by the flame. The power source is configured to selectively modify the electric field to increase or decrease a quantity of the at least one flame root.

摘要： An air blowing fan supplies an amount of air corresponding to a fan rotation speed to a burner during operation. A check valve has a biasing force that closes an exhaust vent, and is opened and closed in accordance with a relationship between a gas pressure in an exhaust passage and the biasing force. A controller performs a failure diagnosis for detecting an open failure of the check valve when a phenomenon in which the gas pressure is lower than a predetermined normal pressure range is detected in a case where the fan rotation speed is within a predetermined diagnosis rotation speed region. The diagnosis rotation speed region is set within a rotation speed range in which a degree of opening of the check valve changes with an increase in the fan rotation speed when the check valve is normally opened and closed.

摘要： The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

摘要： Embodiments are directed to smoking food in an outdoor grill using a customized smoking routine. In one scenario, an electronic controller of an outdoor grill receives an input to initiate smoke generation according to a specified smoke generation pattern, including: adding a specified amount of combustible pellets to a combustion area within the outdoor grill, such that the combustible pellets begin to burn, measuring a current internal temperature of the outdoor grill and, if below a threshold value, adding a specified amount of additional combustible pellets to the combustion area sufficient to raise the temperature to another threshold value, allowing the internal temperature to cool a temperature below the first threshold value and, upon determining that the temperature of the outdoor grill has cooled below the first specified threshold value, adding additional combustible pellets to the combustion area sufficient to raise the temperature to at least the second threshold value.

摘要： A “flame show” is responsive to an audio input signal such as music. A base unit including an analog base unit controller circuit is arranged to receive an audio input signal and generate an analog control signal that is responsive to the audio input signal. The analog control signal is distributed, by wire or wireless, to one or more flame display units such as a “tiki torch.” Each flame display unit has a fuel source, and a proportional valve for controlling an amount of fuel supplied to a burner. Preferably, the control signal controls a gate terminal of a MOSFET semiconductor device, which in turn is coupled to control current in the proportional valve each each unit. By deploying multiple flame display units, all coupled to the same base unit, all of the flame display units contribute synchronously to the overall flame show.
