Abstract
Fires in coal mills are undesirable phenomenon, especially in the case of co-fired biomass. In order to face this problem the detection and prevention system of fire and ignition was created, which has two systems: identify the loss of fuel and fire detection. Logic signals which informs about loss of fuel might be used in control systems of the load and the amount of total air. The logic signal informing about fire detection of the mill is created when the defined threshold value is exceeded by the signal relating the difference in temperatures between the coal-air mixture and its model. It is then successfully used in the system protecting the mill against the propagation of a threat (fire), for example dosaging of chemically neutral gas (water spray)
