Description
Technical field
A kind of nozzle wall temperature measurement device is the utility model is related to, belongs to boiler-burner nozzle wall temperature measurement technology neck
Domain.
Background technology
Traditional boiler-burner nozzle wall temperature measurement method is to be fixed the thermocouple wire for measuring nozzle wall temperature with screw
Onto nozzle inner walls, to obtain nozzle temperature.But the nozzle operation environment temperature due to needing to measure is high, installation space is narrow and small etc.
Feature, thermocouple actual installation are difficult, once and thermocouple by blow loss, it is more inconvenient to replace.
Follow-on nozzle wall temperature measurement method is that the heat-absorbing block with temperature thermocouple is directly welded at nozzle inner walls
On, nozzle wall surface temperature is monitored, and the measurement method peace that this mounting means with thermocouple heat-absorbing block is more traditional
Dress is more convenient.But defect is influenced by nozzle operation high ambient temperature, still there are situation about being blown off by the Secondary Air of higher wind, and heat
After galvanic couple damage, heat-absorbing block is needed together to replace.Narrow space between nozzle inside and outside wall at the same time, the thermocouple volume with heat-absorbing block
It is relatively large, certain trouble is brought to using welding gun welding, the safety and economical operation to boiler cause potentially to threaten.
Utility model content

Really, more convenient, safety and reliability.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of nozzle wall temperature measurement device,
It is characterized in that：Including thermocouple stand apparatus, thermocouple stand apparatus includes pipe, and pipe is connected with pipe fitting one end, pipe
The connector other end is connected with thermocouple wire attachment device；Thermocouple wire is arranged in pipe, and thermocouple wire end passes through pipe fitting
It is connected with thermocouple wire attachment device；
Nozzle inner walls are equipped with boss, and measured hole is equipped with boss, and pipe front end is stretched into the measured hole of boss, and with it is convex
Platform is fixed.
Preferably, the pipe fitting other end is connected through a screw thread fixation with thermocouple wire attachment device.
Preferably, the size of the measured hole and the pipe of thermocouple stand apparatus match.
Preferably, the pipe contact nozzle inner wall.
Preferably, the pipe fitting is located at nozzle exterior.
It is highly preferred that the distance that the pipe fitting stretches out nozzle exterior is more than 5mm.
