Temperature measuring device for outer casing of power station boiler

The utility model provides a temperature measuring device for an outer casing of a power station boiler. The temperature measuring device comprises a temperature information acquisition device, wherein the temperature information acquisition device is arranged in the boiler where temperature is required to be detected, directly transmits the collected temperature data to a boiler control room or transmits all the concentrated temperature information to the boiler control room in a centralized manner through a signal concentrator. Since the temperature monitoring system is introduced into the operational monitoring system of the whole boiler, the temperature measuring device has the advantages that the temperature of the outer casing of the power station boiler is grasped more conveniently and more rapidly; the temperature of the outer casing of the boiler is monitored at proper time, the excess temperature position can be repaired in time, and the thermal efficiency of the boiler is effectively improved; and
