一种新的切换方式在某电厂循环水余热利用项目中的应用

A new circulating water switching method application on waste heat utilization project in a power plant

针对某电厂利用循环水余热供热项目,由于受限于循环水连接管路紧邻变电所存在极大的安全隐患的情况,介绍了一种新的切换方式,即在不影响变电所地基基础的前提下,保证若1台日常接带主机退出后,仍可切换到另1台主机接带余热回收装置,并能顺利切回到日常接带主机接带常态化运行工况。新切换方式应用后,在不影响变电所地基的基础上,提高了余热供热项目的运行可靠性。

Due to great hidden danger by circulating water connecting line was close to the substation in a power plant,a new circulating water switching mode was explored in this paper,that if the daily connect unit stop,another host still could switch to connect with the waste heat recovery unit,and could be smoothly cut back to the daily one.
