Abstract

Abstract: The first domestic proprietary 330-MW circulating fluidized bed(CFB) boiler is developed with a compact-type returning ash heat exchanger(CHE) attached. In order to ensure the stable and economical operation of this boiler, studies on its regulating scheme are performed. Based on the analysis of the methods to regulate the bed pressure, bed temperature, air flow rate and limestone rate, a control scheme and corresponding implementation plan are proposed. The control scheme is characterized by adopting the CHE to adjust the bed temperature and reheated steam temperature. The operation results show that the boiler regulation is quite reliable and flexible, and the temperature in the hot circulating loop is uniformly distributed. In addition, the boiler turns out to be of high combustion efficiency with excellent load variation performance.

Key words: circulating fluidized bed boiler, adjusting scheme, load variation performance
