Internalheat preservation type silicon carbide ceramic/steel composite high-temperaturefurnace smoke pipe is used to extract high-temperature furnace smoke from theboiler and deliver it to the fan coal mill, using the high-temperature furnacesmoke heat to dry the moisture in the brown coal. Its structure is mainlycomposed of silicon carbide ceramic, thermal insulation material, supportstructure and outer protective steel pipe, including straight pipe, bent pipe,single (dual) direction compensator, which can be widely used in the transportationof gas and solid two-phase media below 1350℃ Workingcondition.

Siliconcarbide ceramics are made by high-temperature sintering. They are mechanicallyconnected to the outer protective steel tube without falling off. The expansionjoints and seals are installed inside to achieve self-compensation. The wear isslight during use, which effectively improves the reliability of the equipmentand reduces the operating cost, and the service life can reach 30 years.
