Power station coal-fired boiler combustion center flame deflection detection device

A power station coal-fired boiler combustion center flame deflection detection device acts on a boiler outer wall of a power station coal-fired boiler and comprises a heat collection block and a digital thermocouple sensor. A heat conduction silica gel layer is arranged at the contact position of the heat collection blocks and the boiler outer wall, each heat collection block is provided with a heat collection block fixing hole and a thermocouple inserting hole, and the heat collection blocks are connected with the boiler outer wall through the heat collection block fixing holes. The digital thermocouple sensor is fixedly connected with the heat collection block through the thermocouple insertion hole; and a plurality of digital thermocouple sensors which are connected by field buses and are provided with heat collecting blocks are horizontally distributed along the periphery of the outer wall of the boiler. According to the utility model, the digital thermocouple sensor is used for detecting the change of he
