The invention discloses electric heating equipment. The equipment comprises a plurality of sensors; the device is characterized in that the device further comprises a plurality of independent heating loops, and each heating loop corresponds to an independent control system; the control system receives signals collected by the sensor and controls starting, stopping and power of the heating loop. The plurality of control systems are mutually redundant and backup, and state monitoring and control are carried out on the heating loop by utilizing the characteristic that the difference value between the heating powers controlled by the plurality of control systems under the normal condition is smaller than a set threshold value. The technical scheme has the advantages that the independent heating loop and the control side of the independent heating loop are independent, redundant and backup, so that high-pressure safety and temperature safety of the heater are ensured; the device has the mutually redundant low-flow heating or dry burning detection and processing functions.
本申请公开了一种电加热设备,所述设备包括若干传感器;其特征在于,所述设备还包括多路独立的加热回路,每个加热回路对应独立的控制系统;所述控制系统接收传感器采集的信号,控制加热回路的启停和功率;多个控制系统互为冗余和备份,利用正常情况下多个控制系统控制的加热功率之间差值应小于设定阈值的特点,对加热回路进行状态监测和控制。本申请的技术方案优势在于通过设置独立的加热回路及其控制侧独立,互为冗余、互为备份,确保加热器高压安全和温度安全;具有互为冗余式的低流量加热或干烧检测及处理功能。
