Incinerator supply amount detection system, incinerator operation control system, incinerator supply amount detection method, and incinerator operation control method

A supply amount detection system for an incinerator, which detects the amount of solid fuel to be supplied to a combustion chamber of the incinerator, is provided with: an imaging device configured so as to capture an image of the solid fuel before the solid fuel accumulated in a supply section of the incinerator falls into the combustion chamber; and a detection device that detects the amount of solid fuel supplied to the combustion chamber on the basis of the image captured by the imaging device. 检测向焚烧炉的燃烧室供给的固体燃料的量的焚烧炉的供给量检测系统具备：拍摄装置，其构成为拍摄堆积于焚烧炉的供料部的固体燃料向燃烧室落下之前的固体燃料的图像；以及检测装置，其基于由拍摄装置拍摄到的图像，来检测向燃烧室供给的固体燃料的量。
