    摘要: Provided is a solid fuel burner (60) suitable for controlling a flame to be formed by combustion of fuel ejected from the burner (60) and a temperature distribution in a furnace, a combustion apparatus using the solid fuel burner (60), and a method of operating the combustion apparatus. Providing in the fuel nozzle (10) a plurality of gas ejection nozzles (81), (82) and a restriction (obstacle) (19) downstream thereof, and ejecting a relatively large amount of gas from a portion of the gas ejection nozzles (81) provides a circumferential distribution in fuel concentration. Further, having the restriction (obstacle) (19) on a downstream side increases a deviation in fuel concentration. Providing a fuel concentration deviation in the circumferential direction makes it possible to change the forming position of a flame. Therefore, regulating the flow rate of gas flowing through the gas ejection nozzles (81), (82) makes it possible to control constant the temperature of combustion gas at a furnace exit, the temperature of a heat transfer tube provided on a furnace wall surface, the temperature of a fluid flowing through the heat transfer tube, or the temperature of a heat transfer tube provided in a furnace or at a downstream-side flue portion thereof and the temperature of a fluid flowing through the heat transfer tube.

    摘要: A mobile phone terminal device checks, in a Manchester determiner, whether or not demodulated data satisfies a predetermined condition for decision exploiting a feature proper to the Manchester code. The Manchester determiner generates a decision signal representing the state of allowance or inhibition, conforming to the decision, and, responsive to the state of allowance of the decision signal. The Manchester determiner allows the demodulated data stored in a buffer to be output. The decision signal is transferred from the determiner to a radio frequency unit and a demodulator. The operation of the radio frequency unit and the demodulator is halted responsive to the state of inhibition of the decision signal.
