Abstract

The circulating fluidized bed boiler because its burning wide adaptability, load and excellent performance of regulatory strong environmental more and more attention to. Lots of circulating fluidized bed boiler in the equipment for optimizing the structure of electric power, improve the power supply quality improve our overall efficiency of using resources and reduce pollutants has an important role. Based on the construction practice during many thermal power engineering, introduced a detailed analysis of the dynamic characteristics of circulating fluidized bed boiler and automatic control system composition, and combined with practical engineering, the circulating fluidized bed boiler unit linkage 125MW control design and installation commissioning technical points are expatiated on its thermodynamic parameters, sensors and DCS control are briefly introduced.
Keywords: large coal-fired plants; The circulating fluidized bed boiler; Linkage control; Thermal parameter point; DCS control
