适用范围:1 Firing systems This European Standard applies to pulverized fuel firing systems of steam boilers and hot water generators and commences at the filling equipment for the boiler bunkers or for the pulverized fuel storage system and ends at the ash extraction plant. For multifuel firing systems using separate or combined burners, these requirements apply to the pulverized fuel firing part involved. For other fuels or firing systems used in combination, other requirements apply e.g. EN 12952-8. 2 Fuels These requirements cover the use of pulverized fuels originating from coal ranging from low to high volatile matter content. This includes e.g. coke, anthracite, bituminous coal or hard coal, lignite or brown coal, petrol coke and oil shale. 3 Operation Requirements for operational equipment apply for steam boilers and hot water generators with permanent supervision by properly trained persons. As firing systems using pulverized fuel may be designed either as direct-firing or as indirect-firing systems, operational requirements have to be differentiated. Annex A summarizes the operational requirements for firing systems including the pulverizing system. 4 Boundary of pulverizing system A pulverizing system is bounded by: — the outlet of the fuel bunkers feeding the mill; — the outlet of the burners fed from that mill; — the points at which the hot air or flue gas and tempering air or flue gas leave their main supply ducts including the primary air fan if associated individually with the mill.
