Fire incineration furnace and waste incineration method using fire grid type waste incinerator

摘要

Problem to be solved: to provide a grid type waste incinerator and a method in which the pusher is operated in accordance with the supply of waste to the grid, and the appropriate waste layer can be stabilized.Incinerator 1 isAn infrared camera 13 is provided on the downstream side wall of the combustion chamber to obtain thermal image information of waste on the gridFrom a thermal image information, a data processor 14 for obtaining a measured thickness value as an actual measurement value of the thickness of a waste layer on the upstream side of the grindstone, andA control device 15 is provided which controls operating conditions for combustion of waste based on the measured thickness value.Control unitThe thickness of the measured layer is compared with the appropriate target thickness range.If the thickness of the measured layer is higher than the target thickness range,It is judged that the waste volume on the grid 5 is excessive, andThe stroke width of the pusher of the dust supply 4B as the operating condition is reduced.If the thickness of the measured layer is lower than the target thickness range,It is judged that the waste volume on the grid 5 is overrun.The stroke width of the pusher as an operating condition is increased.Diagram
