管式轻型原油加热炉在原油长输管道中的应用非常广泛,为了有效控制加热炉的油风比例,达到安全、低耗、高效运行的目的,监控系统的开发与应用就显得尤为重要。从管式轻型加热炉监控系统的控制原理、结构性能及技术特点进行论述。整个监控系统以可编程逻辑控制器(PLC)为内核对加热炉进行监控,其主要功能有监视、控制、报警、异常工况识别、自动保护等。实际应用效果表明该系统功能齐全、性能稳定适用于原油加热炉监视及自动控制。
The application of tubular light crude oil heating furnace in crude oil long distance pipeline is very extensive. In order to effectively control the ratio of oil and wind in the heating furnace and achieve the purpose of safe, low consumption and high efficiency operation, the development and application of monitoring system are especially important. From the tube light heating furnace control system control theory, structural performance and technical characteristics are discussed. The entire monitoring system with programmable logic controller (PLC) as the core of the heating furnace to monitor the main functions of monitoring, control, alarm, abnormal condition identification, automatic protection. The actual application shows that the system is fully functional and stable in performance. It is suitable for crude oil heating furnace monitoring and automatic control.
