Method and device for monitoring and controlling the combustion of a solid fuel which moves as a layer in a combustion chamber

摘要

There are established, with the aid of a motorised infra-red thermometer 16, thermal images of the combustion of coal moving continuously over a grate 2, from which thermal images the curve of the temperatures picked up in line with the blowing nozzles 6 is compared with the preset theoretical curve for the corresponding rate, for the purpose of modifying the distribution of air to the said nozzles depending on the observed discrepancy. Application to continuously operating coal-fired boilers.
