Thermocouple

Brief Introduction:
Wear-resistant material processing techniques;
Surface layer of the new alloy may be provided with extremely high
Surface hardness of the processed tungsten-carbon alloy is up to Rockwell HRC76
Surface alloy layer and the base material of stainless steel belong to one piece, their heat expansion coefficient and brittle behavior are completely identical, and no cracking may take place in case of high heat.
 

Details:
Circulating fluid bed (CFB) boiler is provided with good environment-protective performance, it is also characterized by high fuel adaptability, strong capability in load regulation, and convenience in comprehensive utilization of clinker, and thus it has been increasingly regarded in many countries. In recent years, more and more power plants in China have adopted boilers that run as per the technology of circulating fluid bed, the capacity of generator sets has get higher and higher. In “Tenth Five-Year Plan”, it is put forward to further optimize the construction of thermal power generating units and to promote the popularization and application of circulating fluid bed boilers. The utility boilers 440t/h (CFB), which have been developed into mature products, are making giant strides as bamboo shoots after a spring rain. However, the problems such as corrosion resistance, wear resistance, and vibration resistance of thermocouple applied in detection of combustion system of a boiler always assail the operation of utility boilers, and these are the biggest difficulties to be solved by the thermal control
