Power plant core equipment such as boilers, steam turbines, and steam pipelines operate under high-temperature and high-pressure conditions for extended periods, where thermal insulation performance directly impacts unit thermal efficiency and operational safety. PLUS blankets are specifically developed as an upgraded ceramic fiber blanket designed to withstand these harsh operating conditions
The boiler body and furnace wall—PLUS blankets serve as the inner lining of the furnace wall, capable of withstanding high-temperature impacts above 1,260°C. After adopting a ceramic fiber blanket composite structure in a 600MW unit, the heat dissipation loss of the furnace wall decreased by 28%, and the flue gas temperature dropped by 15°C.
Main steam pipe and reheat pipe – The main steam temperature in power plants reaches up to 540-566°C. When wrapped with PLUS blankets, it can significantly reduce heat loss during steam transportation and improve unit thermal efficiency.
Turbine Cylinder Insulation — Due to continuous vibration during turbine operation, traditional rigid calcium silicate boards are prone to cracking, fracturing, and powdering. PLUS blankets utilize flexible materials, conforming to complex shapes such as cylinder surfaces and flanges, while offering excellent vibration resistance and thermal cycling performance.
