    • A reaction state at an upstream portion of the catalyst unit in which a partial oxidation reaction occurs is detected by a first reaction state detector, and a reforming reaction state in the whole of the catalyst unit composed of a catalyst for promoting a steam reforming reaction and a catalyst for promoting a partial oxidation reaction is detected by a second reaction state detector. Based on a reaction state detected by the second reaction state detector, a first corrector corrects feed amounts of raw fuel gas and oxidation gas, which are supplied to the catalyst unit, and a second corrector corrects a feed amount of the oxidation gas supplied to the catalyst unit and/or a feed timing thereof, based on the reaction state detected by the first reaction state detector.
    • 通过第一反应状态检测器检测发生部分氧化反应的催化剂单元的上游部分的反应状态,以及由促进蒸汽重整反应的催化剂构成的催化剂单元整体的重整反应状态,以及 通过第二反应状态检测器检测促进部分氧化反应的催化剂。 基于由第二反应状态检测器检测到的反应状态,第一校正器校正供给催化剂单元的原料燃料气体和氧化气体的进料量,第二校正器校正供给到催化剂单元的氧化气体的进料量 催化剂单元和/或其进料时间,基于由第一反应状态检测器检测的反应状态。

    • A highly reliable, fail-safe circuit for a control system wherein a controlled device will always receive a control signal derived from a main control circuit when the main control circuit operates normally even if a back-up control circuit backing up at least one function of the main control circuit which is a minimum requirement for an operation of the controlled device fails or wherein a controlled device will receive a control signal derived from the back-up control circuit when the main control circuit fails. Replacement of the control signal from the main control circuit with a back-up control signal from the back-up circuit is carried out only when the back-up circuit outputs a particular signal at or near a predetermined frequency or alternatively when the back-up circuit outputs a plurality of parallel logical signals in a predetermined combination.
    • 一种用于控制系统的高度可靠的故障安全电路,其中当主控制电路正常工作时,受控设备将总是接收从主控制电路得到的控制信号,即使后备控制电路备份至少一个功能 作为受控设备的操作的最低要求的主控制电路故障,或者当主控制电路发生故障时受控设备将接收从备用控制电路导出的控制信号。 只有当备用电路输出特定信号在预定频率处或接近预定频率时,或者备用时,只能从备用电路用来自主控制电路的控制信号替换来自备用电路的备用控制信号 电路以预定的组合输出多个并行逻辑信号。
