Research on Calculation Model of Relationship between Wet Basis and Dry Basis Oxygen in Boilers
Oxygen content is an important index for calculating boiler efficiency.At present,there is no equipment to measure dry basis oxygen directly in thermal power plants.In the usual calculation methods,wet basis oxygen is directly calculated as dry basis oxygen,which has a great influence on the accuracy of calculating boiler efficiency.The calculation methods of Performance Test Code for Utility Boiler and Calculating Method of Economical and Technical Inder for Thermal Power Plant are analyzed in depth.Through the analysis and derivation of boiler variable working conditions,the accurate calculation model of dry basis oxygen of the unit firing high-moisture lignite is obtained,which greatly improves the calculation accuracy of boiler efficiency.It is suitable for the unit firing any kind of coal and has extremely high popularization value.
