Design Optimization and Improvement of High-Temperature and Ultrahigh-Pressure Four-Unit Power Generation System
With the popularization and application of clean heat recovery coke ovens,the in-stalled scale of coke ovens continues to become larger,and the flue gas waste heat resources become more and more abundant and urgent to recover.Aiming at the problems of small capacity,high quan-tity,low parameters and low power generation efficiency of waste heat boilers,the first high-temperature and ultra-high-pressure with common header four-unit power generation project for clean-type heat-recovery coke oven was designed and implemented in China.This article discusses the optimized layout of the general plan,the determination of the process system scheme,the opti-mized design of the four major pipelines and the circulating cooling water system,the development and implementation of the installation and commissioning and pipe blowing scheme,and elaborates the problems of the commissioning and implementation process.Practice has proved that this type of high-temperature and ultra-high-voltage four-unit power generation system belongs to high-efficiency and energy-saving power generation technology,which is worthy of wide popularization and application.
