摘要

介绍神火环保示范电站 1 35MW机组分散控制系统

重点介绍国产 4 40t/h超高压循环流化床(CFB)锅炉的控制方案

包括对负荷、床温、床层厚度、风量、冷渣器、石灰石给料等的控制。该控制方案充分考虑了CFB锅炉的运行特点

并针对以往CFB锅炉在测温点布置方面存在的不足

提出了改进措施

Abstract

The distributed control system (DCS) of 125MW unit has been presented

emphatically describing the control scheme of home made 140t/h super high pressure circulating fluidized bed (CFB) boiler

including control systems of load

bed temperature

thickness of bed layer

air flow rate

slag cooler

and limestone feeding etc.

The operation specialities of CFB boiler have been fully considered in the said control scheme. Directing against the deficiencies existing in the aspect of arranging the temperature measuring points in previous CFB boilers

improvement measures have been put forward.
