ON-LINE SUPERVISION SYSTEM OF UTILITY BOILERS EFFICIENCY AND EMISSIONS

摘要

The present situation of the European electricity market demands to reconsider all fossil power plants operating procedures from a new market perspective. Large coal-fired power stations were conceived to operate continuously at nominal load. In the 90s and 00s, cyclic load was adopted in many power stations, in order to meet the electricity demand. This followed more or less fixed schedules, being mainly due to the necessary base-load operation of nuclear installations. Research attention logically turned to several questions relevant under these circumstances, such as remaining life of components, auxiliary power consumption, sliding pressure and other forms of improving partial load operation.
