摘要

为了提高生物质锅炉燃烧效率、降低烟气污染

以燃烧控制系统为对象

针对某自备电厂生物质锅炉控制系统应用中存在的鲁棒性差、精度低等问题

通过分析生物质燃烧过程

基于PLC设计了生物质锅炉燃烧控制系统。应用表明

该控制系统的稳定性和调节速度均较好

蒸汽压力最大超调量为0.5%

响应时间为65s。

Abstract

To improve combustion efficiency and reduce flue gas pollution in biomass-fired boilers

the combustion control system was taken as the research object and the problems like poor robustness and low accuracy occurred in a power plant were investigated.Through analyzing the biomass combustion process

a control system using Siemens S7-300 programmable logic controller(PLC)was presented.The practical application shows this control system has good performance in stability and response speed

of which the maximum overshoot of the steam pressure is 0.5%

and the response time is 65 s.
