Model and control of a waste combustion process

摘要

The present invention is concerned with a model of a waste combustion process which is accurate and of limited computational complexity at the same time and thus is suitable for controlling or simulating a waste incineration plant. A pile of waste is represented by two layers, and the heat transfer from a gas combustion phase or flame above the pile is limited to a heat radiation interaction between the flame and the upper one of the layers. The resulting model-based controller for a waste incineration grate takes into account a variability of the waste composition via a filtered white noise. The controller can assist the operator in maintaining constant process conditions and maximizing the throughput of the plant at constant energy output, or realize a training simulator to educate operators in running a waste to energy plant secure, reliable and efficient. <IMAGE>
