Introduction

Positive pressure ash handling system take the compressed air as the power, conveying the ash from economizer, preheater and dust separator to gas-partical flow system through hopper, feeding valve and and ash pipe.The advantages of this system are: the conveying pressure is high (no less than 0.2MPa), the conveying distance is long, the conveying concentration is high and is very high efficiency. Tandem pump single tube and furbelow pipe pressurized seal ash handling system is the typical of pressurized seal ash handling system. This system is well designed with simple structure, which makes the operation and maintenance easy, so it is widely used in modern ash handling industry.
