<p>[Problem] To provide a cremation method and a cremation system comprising a catalytic device that efficiently decomposes and removes toxic substances contained in exhaust gases from a crematory furnace and that prevents clogging of a catalytic cell by driving a dust removing device while a catalytic unit is loaded in a catalytic tank. [Solution] A cremation system is provided with an upper catalyst set (22) into which exhaust from a dust collector is introduced, a lower catalyst set (22') disposed in series with the upper catalytic set (22), a dust removing sprayer (222) for removing dust, particles, or the like adhering to a catalytic tank (221), a plurality of nozzles that are provided on the sprayer (222) and that discharge high pressure gas, a drive motor for the dust removing sprayer (23) for moving the sprayer (222), a valve (25) that controls supply of high pressure gas to the nozzles, and a pressure sensor for measuring pressure differences between an inlet and an outlet for a gas flowing in the catalytic cell. A dust removing device is run when the pressure difference reaches or exceeds a prescribed value, and dust or the like adhering to the catalytic cells is removed.</p> |
