Temperature measurement of boiler pulverizing system


The measuring point of the boiler pulverizing system and especially the outlet of the coal mill are seriously worn. Therefore, the selection of temperature casing pipe is very important. We suggest using high-temperature wear-resistant alloy or tungsten cobalt alloy to resist wear.

At the outlet temperature measuring point of the coal mill, the temperature casing pipe is seriously worn under the erosion of high flow velocity pulverized coal particles. Its service life often cannot meet the requirements of stable operation of the unit. Therefore, the selection of wear-resistant casing pipe is very important, and its toughness and hardness shall be considered at the same time. Recommended product is TRK-S02/CoW-Φ-U-L/PA31C06/SY.
