Pulverized coal burner
Burners of coal-fired boilers are prone to wear, burning loss, deformation, cracking and other problems, which affect boiler efficiency and ultra-low emission indicators. The above problems can be effectively solved by making use of SiC materials and lining the whole SiC materials on the vulnerable parts of the burner, as the SiC materials have some good characteristics, such as good wear-resistant performance, high temperature resistant performance, thermal shock resistant performance and so on. It is useful to improve the reliability and service life of the burner. Focusing on the using conditions of different positions on burners, the different properties of SiC materials can be adopted.

Thermal insulation composite high-temperature furnace flue gas pipe of SiC linings anf steel casting
The internal insulation composite high-temperature furnace flue gas pipe of SiC linings anf steel casting is used to extract high-temperature furnace flue gas from the boiler and deliver it to the fan pulverizer, which is to dry the water in the coal by using heat of high-temperature furnace flue gas. Its structure is mainly composed of silicon carbide ceramics, thermal insulation materials, support structure and external steel pipe, including straight pipe, bent pipe and single (dual) direction compensator. It can be widely used in the transportation of gas-solid two-phase media below 1350 ℃.
SiC are sintered at high temperature. They are mechanically connected to the external steel pipe without falling off. Expansion joints and seals are set inside to realize self compensation. In operation process, the product has slight worn, which is effective to improve the equipment reliability, and reduce the operating cost. With simple structure, the product is easy to install and achieves the long service life with over 30 years.
