汽轮机旁路排放蒸汽流量计算及优化的研究

摘要

Based on enthalpy unattended constant thought, to temperature, and pressure amendment enthalpy value alternative amendment density of method, through once curve intends collection, get accuracy larger of bypass steam flow calculation formula, improve has manufacturers valve parameter in engineering calculation in the of application, while expanded has flow calculation of application range, enhanced has on different power station, and different DCS dealer, and different valve manufacturers of adaptability and feasibility, for engineering application provides has accurate, and simple of debugging method, and for steam (gas) State workers quality flow calculation provides has new thought.%基于焓值守恒思想，以温度、压力修正焓值替代修正密度的方法，通过一次曲线拟合，得到准确性较大的旁路蒸汽流量计算公式，提高了厂家阀门参数在工程计算中的应用，同时扩大了流量计算的应用范围，增强了对不同电站、不同DCS供货商、不同阀门厂家的适应性和可行性，为工程应用提供了准确、简捷的调试方法，并为汽（气）态工质流量计算提供了新思路。
