Gas injection thermocouple is an indispensable thermocouple in ammonia plant, increasing servicelife by blowing nitrogen or instrument air to force harmful gas out of thermowell, or preventing entryof harmful media by making the inside thermowell pressure greater than the furnace pressure.
It is applicable to measure temperature of more than 1000'c, with the thermowell material of corundumor carborundum. High temperature thermocouple has type of S, R and B of noble metal. Commonly, ithas the structure of assemble.
A multi-point flexible thermocouple suitable for temperature measurement in butanediol (BDOsynthesis reactors, with a maximum operating pressure rating of 2500 # (design pressure of 34.8MPaand design temperature of 204 '℃), and equipped with a pressure instrument for leakage detection.
It is used in coal-water slurry water-cooled wall gasifier (Tsinghua furnace, Jinhua furnace, Luxi furnace, etc.); There are 3 temperature sensors, two K-type and one B-type, the K type is used to measure the temperature of the annular cavity and the water wall temperature, and the B type is used to measure the temperature of the furnace combustion chamber, and the double-layer anti-leakage and detachable structure are set.
Our company has a variety of multi-point thermocouples suitable for ethylene glycol reactors. According to the process requirements, it can be divided into: single branch multi-point, multi-branch multi-point; Fixed, core-pullable, leak-proof and so on.
It is suitable for temperature measurement inside various reactors, especially hydrogenation reactors, with multiple independent casings fixed with T-beam brackets to prevent casing from bending, and equipped with sealing chambers and leakage detection pressure gauges.
The cross-shaped temperature measurement thermocouple is a product developed by our company for measuring the temperature at the top of the blast furnace. Four sets of thermocouples are arranged in a cross layout, allowing for maintenance and replacement of thermocouples without shutting down the furnace. The thermocouple is held firmly against the inner wall of the casing by a spring, ensuring more accurate temperature measurement and more sensitive response.
