Practice and application of energy consumption analysis system on CFB heat supplying unit

Abstract

Abstract: The structure and function of energy consumption analysis system on CFB heat supplying unit in Zibo Cogeneration Co., Ltd were introduced. Taking use of real-time data and associated with CFB boiler running characters, unit coal consumption can be calculated, key factors which influence coal consumption and the elaborate factors which effect boiler efficiency, steam turbine heart consumption and self-service consumption ratio can be analyzed which the result can guide the unit operation. In order to proven accuracy of the system, more research work is carried out in several parts: the relation of bed temperature control with boiler efficiency, economical character adjusting basis of cogeneration unit and energy saving evaluation criterion, operation evaluation indexes system and so on. Practices show that: the coal consumption of #3, #4 units is decreased, and the unit operating economics efficiency is improved with using this analysis system .

Key words: CFB, energy consumption characteristic, energy conservation analysis, cogeneration
