Compared to the prior art, this utility model has the advantage that
1) judging whether that the method for not siphunculus is simple by wall temperature change, result is accurate, and will not be to be checked
The equipment of looking into damages；
2) temperature measuring equipment simple in construction, easy for installation；
3) point position has mobility, can measure for emphasis position；
4) equipment can monitor in real time, finds not siphunculus automatic alarm.
In a word, during this utility model solves superheater Chemical cleaning due in burner hearth ambient temperature height cannot be carried out people
The problem of work monitoring；This utility model feedback time is short, accuracy rate is high, and automaticity is high, solves what prior art existed
A series of limitation；Use this utility model, it is possible to achieve during superheater Chemical cleaning, pipeline blockage situation side by side is real-time
Monitoring, it is to avoid after Chemical cleaning, the booster phenomenon produced because pipeline is obstructed during unit starting, for the success of Chemical cleaning
Carry out providing guarantee.
Accompanying drawing explanation
