Calculation Method of Attemperation Water Flow in Changing Steam Flow Condition

摘要

In order to control the attemperation water demand, the superheater heating ability is calculated by enthalpy increment. According to the changed enthalpy of the superheater outlet, the attemperation water demand is estimated. To simplify calculation, the changing steam flow is regarded as linear process during a certain time. Thus, the attemperation water calculation method is obtained. Basis on this, Matlab software is used to perform computer simulation to the system.
