Circulating fluidized bed has its outstanding advantages in terms of energy saving, emission reduction, and load control. It is highly respected in today's environmental protection rectification. However, in actual use of circulating fluidized bed, process temperature control has always been a problem that needs to be addressed urgently. The Circulating fluidized bed boiler wear-resistant thermocouple has a short life during use and is fragile, which makes it particularly troublesome to replace it later. Why is the service life of the circulating fluidized bed boiler wear-resistant thermocouple so short?

There are three aspects in the circulating fluidized bed that affect the service life of the thermocouple. 

1. The temperature in the circulating fluidized bed boiler is very high, at 900-1100 degrees, which is a high temperature environment. There are certain tests on the life of the thermocouple components and the casing. 

2 Circulating fluidized bed boilers often have particles with very fast flow rates, strong erosion properties, and high requirements for the wear resistance of thermocouples. 

3, Circulating fluidized beds emit strong corrosive sulfides due to pulverized coal combustion. As a result, the thermowell is easily corroded. The total of the above results in the service life of the wear-resistant thermocouples of the circulating fluidized bed boiler being very low. The service life of the manufacturer is only 1-2 months. As a professional thermocouple manufacturer, we can customize the circulating fluidization by improving the materials. Bed boiler thermocouples have a service life of only 6-8 months.

The scheme used by AnHui Tiankang(Group)Shares Co., Ltd has these changes: 

1. Compared with similar products, the overall deep-drilled casing has higher hardness, which effectively improves the erosion resistance of the thermocouple; 

2. We choose high chromium cast iron as the Outer casing, because the chromium content in high chromium cast iron reaches 30%, this will have excellent heat resistance, wear resistance and oxidation resistance; 3, the length of the wear head is as long as possible to ensure impact resistance in the boiler.

In short, the circulating fluidized bed boiler wear-resistant thermocouple has always been a product that needs to be prepared in actual use. In addition to improving its service life, it is also important with the size of the boiler opening, the actual temperature in the furnace, and the material of the wear-resistant head The influence of factors is welcome. Users are welcome to customize the wear-resistant thermocouples that are more suitable for you according to the working conditions of the circulating fluidized bed on site and ours.
