PROBLEM TO BE SOLVED: To provide a waste material combustion installation for actualizing combustion control while properly determining the combustion condition of refuse charged into a furnace. SOLUTION: The waste material combustion installation comprises an image processing part 35 for applying image processing to the picked-up images of the inside of a fluidized bed combustion furnace 1 for refuse combustion to extract the contour figures of a combustion region, a fractal dimension computing part 36 for finding the fractal dimensions of the contour figures obtained by the image processing part, and a parameter determining part 37 for determining control parameters to control the supply amount of secondary air and the supply amount of refuse in accordance with the fractal dimensions found by the fractal dimension computing part. When the fractal dimension is smaller than a smaller threshold value out of two greater and smaller threshold values showing the range of a normal combustion condition, the supply amount of the refuse and the supply amount of the secondary air are less than those in the normal combustion condition. When the fractal dimension is greater than the greater threshold value, the supply amount of the refuse and the supply amount of the secondary air are controlled to be less and more, respectively, than those in the normal combustion condition.
