摘　　要：针对热电站中采用表面式减温器的锅炉汽温自动调节系统和给水自动调节系统之间存在互相干扰等问题 ,经现场探索 ,给出了用减温水流量反馈引入副环组成的串级汽温自动调节方案。提出了解决其它相关问题的一些措施。投入运行后 ,主汽温度和汽包水位稳定 ,效果良好。To against the mutual interference between automatic regulating systems for boiler steam temperature and feedwater in thermal power station using surface type temperature rerducer, through investigation, a cascade steam regulating strategy using the feedback of temperature reducing water as secondary input is given. Some measures for resolving related problems are also stated. In operation, both main steam temperature and drum are stable.
