An intelligent coordinated control strategy has been proposed and successfully applied to 300MW circulating fluidized bed (CFB) units in China. The paper describes an intelligent coordinated control (ICC) system to overcome the long settling time, strong coupling, nonlinearity and inconstancy encountered in CFB combustion. ICC is based on both fuzzy(More)
An coordinated control strategy has been proposed and successfully applied to 300MW circulating fluidized bed (CFB) units in China. The paper describes the new coordinated control (NCC) system to overcome the long settling time, strong coupling, nonlinearity and inconstancy encountered in CFB combustion. NCC is based on both fuzzy Feedforward (fuzzy-FF)(More)
An intelligent coordinated control strategy has been proposed and successfully applied to 135∼300MW circulating fluidized bed (CFB) boiler-turbine units in China. Because the combustion system of the CFB is a complex object characterized, it is difficult to build precise mathematic model and control it with traditional control theory. The paper(More)
The logical range of laser power density and optimum laser power density were explored for multi-element analysis of pulverized coal flow with laser-induced breakdown spectroscopy in the present paper. The range of laser energy was chosen from 20 to 160 mJ in the experiment. Pulverized coal less than 200 microm in diameter of particles fell freely through(More)
