本文介绍了本室研制的锅炉微机监控系统。本系统可对锅炉32点(可扩充至64点)参数进行集中监视和越限自动报警;对锅炉水位、主蒸汽压力、主蒸汽温度、炉膛负压和烟气中的含氧量进行闭环控制。本系统首先在黑龙江涤纶厂热电站35T/H燃煤锅炉上安装投运,经一年多运行验证,操作、维护简单,工作稳定可靠,经济效益显著,节煤率达8～10％,包括节电每年可创经济效益24余万元。
This article describes the boiler room developed by computer monitoring system. The system can monitor the boiler 32 points (can be expanded to 64 points) parameters and automatic alarm over the limit; the closed loop control of the boiler water level, the main steam pressure, the main steam temperature, the furnace negative pressure and flue gas oxygen content . The system is first installed and put into operation on the 35T / H coal-fired boiler of Heilongjiang Polyester Thermal Power Plant. After more than one year of operation, the system has been verified and operated with simple maintenance, stable and reliable operation and remarkable economic benefits with a coal saving rate of 8% to 10% Energy-saving annual savings of more than 240,000 yuan.
