    • PROBLEM TO BE SOLVED: To provide a compact warmer capable of warming grilled food on a skewer while keeping the flavor appealing both in sight and smell and allowing a user to easily take in/out the food and easily clean the warmer.
      SOLUTION: The warmer of the grilled food on the skewer comprises a basket-type storage body 3 for storing the grilled food 2 on the skewer, with a plurality of openings in the periphery and a tray 4 on the bottom for reserving liquid matter, a far-infrared radiator body 13 for storing the basket-type storage body 3 and radiating far-infrared rays from the periphery of the basket-type storage body 3 to the grilled food 2 on the skewer, a warmer body 1 with an take-out opening, and a sheathed heater 14 for irradiating far-infrared rays from the far-infrared radiator body 13. The basket-type storage body 3 and the far-infrared radiator body 13 have guide parts to guide the basket-type storage body 3 sliding inside the far-infrared radiator body 13 to a prescribed position on the bottom board, and the space between the basket-type storage body 3 and the far-infrared radiator body 13 is maintained.

    • PROBLEM TO BE SOLVED: To provide a fluidized bed boiler monitoring device for accurately detecting abnormality in a fluidized condition or in a furnace in a short time. SOLUTION: The fluidized bed boiler monitoring device comprises a FFT frequency property calculating means 95 for calculating a power spectrum per frequency and a dimensionless power spectrum per frequency in which the power spectrum per frequency is made dimensionless in accordance with a differential pressure value inside a fluidized bed and a differential pressure value outside the fluidized bed, a first abnormality determining means 97 for calculating a high frequency strength factor as a change factor before/after a FFT treatment interval for all power spectrums in a first preset frequency band based on the power spectrum per frequency and determining abnormality in the furnace, and a second abnormality determining means 99 for determining that a fluidization index value in which an average value for all power spectrums in a preset time is made dimensionless, in a second preset frequency band based on the power spectrum per frequency in which a decibel value for the dimensionless power spectrum per frequency is a preset decibel value or greater, shows the abnormality of fluidization.
