合成锅炉给水泵汽改电后的合成锅炉汽包液位三冲量调节系统

Regulation System with Three Impulses for Liquid Level in Steam Drum of Boiler in Synthesis Section after Replacement of Steam by Electricity for Feedwater Pump of Boiler in Synthesis Section

合成锅炉给水泵 (10 4J)实施汽改电节能工程后 ,原合成锅炉汽包 (10 1F)液位三冲量调节系统不再适用于电泵控制 ,为此新增 1套调节系统以满足电泵控制。介绍新增调节系统的结构、原理、仪表功能、调节过程以及电泵与汽泵的倒泵运行。

After completion of the project of replacement of steam by electricity for the boiler feedwater pump(104J) in the synthesis section, the original three-impulse regulation system for liquid level in the steam drum (101F) of the boiler is no longer suitable for the control of the electric pump, so a new set of regulation system is added to carry out control of the electric pump. This paper describes the newly added regulation system with respect to its configuration, principle, instrument functions, regulation procedure, and shift operation of the electric and steam pumps.
