摘要:
PROBLEM TO BE SOLVED: To provide a combustion equipment for a circulation type grain drier capable of shortening the time for clearing up the cause of extinguishment of combustion flame (cause of a failure). SOLUTION: A control unit computes a mean value of a plurality of voltage values detected by a combustion flame monitor unit, and when a mean value detected this time is smaller than that of last time continuously several times, the control unit determines that a flame rod is failed. The control unit also computes a value ΔA obtained by subtracting the mean value of this time from the last mean value, and when an absolute value of ΔA is out of the predetermined threshold value range several times, the control unit determines clogging of a fuel filter. With this structure, since extinguishment of the combustion flame can be thereby detected early before the flame is extinguished, when the combustion flame extinguishes, inspection of the fuel filter and the flame rod is unnecessary, and the time for clearing up causes can be shortened.

摘要(中):
要解决的问题:提供一种循环型谷物干燥机的燃烧设备,其能够缩短燃烧火焰熄灭的原因(导致故障)的时间。 解决方案:控制单元计算由燃烧火焰监测单元检测的多个电压值的平均值,当该时间检测到的平均值连续数次小于上次的平均值时,控制单元确定 火焰棒失效。 控制单元还计算通过从最后平均值减去该时间的平均值而获得的值ΔA,并且当绝对值ΔA超出预定阈值范围多次时,控制单元确定燃料过滤器的堵塞 。 利用这种结构,由于能够在火焰熄灭之前能够及早检测到燃烧火焰的熄灭,所以当燃烧火焰熄灭时,不需要对燃料过滤器和火焰棒进行检查,能够缩短清除时间。 版权所有(C)2005,JPO&NCIPI
