WASTE SUPPLY AMOUNT MEASUREMENT DEVICE AND METHOD AND WASTE INCINERATION DEVICE AND METHOD

To provide a waste supply amount measurement device and method and a waste incineration device and method for accurately and promptly grasping a supply amount of waste from a chute to a fire grate before combustion of the waste.SOLUTION: In a fire grate type waste incinerator 1, waste on a receiving bed 4A located below a chute 4 receiving charge of waste from outside is push out into a forward combustion chamber 2, and the waste is caused to be dropped and supplied onto a fire grate 5 located below the receiving bed 4A. The fire grate type waste incinerator includes: an infrared camera 13 mounted to a wall part of the combustion chamber 2 and imaging waste on the receiving bed 4A and the fire grate 5 to obtain thermal images; and an image processing device 14 processing the thermal images from the infrared camera 13. The image processing device 14 determines a waste supply amount from the receiving bed 4A onto the fire grate 5 on the basis of a differential image obtained by performing image processing of a difference between a first thermal image obtained by imaging waste at any time and a second thermal image obtained by imaging the waste after a predetermined time after the first thermal image is taken.SELECTED DRAWING: Figure 1 【課題】廃棄物の燃焼前に、シュートから火格子への廃棄物の供給量を正確かつ迅速に把握する廃棄物供給量測定装置及び方法そして廃棄物焼却装置及び方法を提供することを課題とする。【解決手段】外部から廃棄物の投入を受けるシュート４の下部に位置する受床４Ａ上の廃棄物を前方の燃焼室２内へ向け押出して受床４Ａより下方に位置する火格子５上に廃棄物を落下供給する火格子式廃棄物焼却炉１において、燃焼室２の壁部に取りつけられ受床４Ａ上と火格子５上の廃棄物を撮像して熱画像を得る赤外線カメラ１３と、赤外線カメラ１３からの熱画像を処理する画像処理装置１４とを有し、画像処理装置１４は、任意の時刻で廃棄物を撮像して得られる第一熱画像と、第一熱画像の撮像時から所定時間後に廃棄物を撮像して得られる第二熱画像との差分を画像処理して得られる差分画像にもとづき、受床４Ａから火格子５上への廃棄物供給量を求める。【選択図】図１
