The operation of coalfired power plants involves multiple variables which have different levels of importance. A key contributor to an overall expert system is the method used to optimise the coal combustion in the boiler. This is affected by coal quality, boiler cleanliness and equipment deterioration as well as by the even distribution of the

In case of lignite, however, the burners will be exclusively designed as fixed burners. For lignite fired units, the burners are installed at the furnace wall and directed towards a tangential circle. The lignite burners are directly connected with a single mill and depending on the boiler size it will be a 6 or 8 mills arrangement (see Figure ...
