Optimization of grate combustion by means of an IR-camera

The target of the project has been to improve the control and regulation of grate-fired straw boilers by involving measuring signals from a specially developed IR camera in a new regulation concept. The project was carried out with the straw boiler at the Avedøre power station. The conclusion has been that it is a very demanding task to develop an IR camera including software which must function as a process measuring device for continuous onn-line measuring under very demanding conditions in one straw fired boiler. The result showed that this was not possible within the framework of this project. The developed camera has on the other hand proved to be very well suited for measuring campaigns, where the camera is ''manned''/continuously monitored. (Energy 11)
