Research of Uniform Stream Fuzzy Optimization Control in Power-Plant Straight-heating Boiler

On the basis of bias-flow analysis of burning system about power-plant straight-heating boiler and its countermeasures, a control scheme is given for the three fuzzy controller to be built by three pipes export absolute temperature-difference as the input , the openness valve as the controlled object. After realizing this control scheme, the problem of coked heat-pipes in burning process has be resolved perfectly. It makes the heat-pipe´s life increase more than three times. The result of in real running shows the new design scheme is in reason and in effect.
