  • Introduction
  • Specifications
As the popularity of circulating fluidized bed (CFB) boiler used in Chinese power industry, it is a priority task to adopt anti-high temperature, anti-corrosion, anti-abrasion furnace thermocouple to control inner boiler temperature. Circulating fluidized bed boiler temperature control points are mainly as following:
1. Main bed of Fluidized bed
Fluidized bed dense phase region,temperature range 0~1100℃. Medium contains pulverized coal and H2S、SO2、NH3、CO2 strong corrosive gas. The washing strength of fluidized material is very strong.
Fluidized bed rare region, temperature range 0~1100℃.The fluidized material has strong washing strength and contains corrosive gas.
2. Entrance of cyclone separator, temperature range 0~900℃. There is high-speed airflow about 25~27m/s at entrance and contain granular media. It has strong washing strength.
3. fluidized bed slag cooler, temperature range 0~800℃ and contain granule and CO、CO2、SO2、H2S corrosive gas.
In view of the above measure environment, the company develops a new generation thermocouple which is anti-high temperature, anti-corrosion and anti-wear. The product is durable, safe, reliable and long life. it is used to measure temperature within 0~1300℃. It is a un-instead thermocouple protection tube which made in alumina, aluminum, graphite, oxides of silicon carbide and other materials. It is the first choice temperature sensor in circulating fluidized bed boiler.
