STEAM PRESSURE POLE-PLACEMENT ADJUSTMENT METHOD OF STRAW BURNING CIRCULATING FLUIDIZED BED BOILER

摘要

Provided is an adjustment method for steam pressure pole-placement of a straw burning circulating fluidized bed boiler. The method calculates a steady state target value of an intermediate variable and a steady state target value of a straw burning amount according to a target value of the steam pressure, establishes a continuous time dynamic model of equivalent steam pressure and straw burning, further designs a steam pressure automatic adjustment controller for the straw burning circulating fluidized bed boiler, so as to achieve the automatic adjustment of the steam pressure of the straw burning circulating fluidized bed boiler for the target value. The method is easy to achieve the adjustment of steam pressure pole-placement of the straw burning circulating fluidized bed boiler.
