用SLPC可编程调节器实现对废热锅炉上锅筒水位的自动控制

Automatic Control of Heat Recovery Boiler Drum Water Level by Use of a SLPC Programmable Regulator

结合工程实例,介绍了一种用可编程调节器构成的废热锅炉上锅筒水位的三冲量自动控制系统,给出了各冲量的定标公式,并列出了该系统的控制程序。

In connection with practical engineering examples the authors present a three-element water-level automatic control system for a heat-recovery boiler drum, which incorporates a programmable resulator. Given in the paper are calibration formulas and the control sequence of the said control system.
