Pneumatic Conveying System ( PCS) provided by PSPL are designed to handle a wide range of particle sizes and bulk densities, from fine powders to pellets, with bulk densities ranging from 16 to 3200 kg/m³. These systems are highly versatile, capable of handling particles up to 50 mm in diameter. PCS are ideal for efficient material transport in various industrial applications, including ash handling and bulk material unloading.
Dilute phase conveying is the most commonly used system of conveying materials. This type of system requires relatively large quantity of air to convey a comparatively small amount of material at lower pressures. The material is conveyed at high velocities through the system. It is commonly referred to as suspension flow because the particles are held in suspension in the air as they are pushed (Pressure) or sucked (Vacuum) through the conveying conduit. To maintain the material in suspension, it is necessary to maintain velocity little more than pick-up velocity.
PSPL designed Dense Phase Conveying System offers the enormous advantage of efficiently "pushing" a much denser concentration of bulk solids at relatively low velocities through a conveying line. The dense phase systems uses low air volume, medium pressure. This system uses a transfer vessel to feed the material into the conveying line. The velocity at the source can be as low as 2 m/s for the majority of materials. The product velocity at the destination is always a function of the system differential pressure, but in most cases, it rarely exceeds 15 m/s.
Pneumatic conveying systems, is ideal solution to handle Ash especially in industries such as power generation and manufacturing to handle boiler Ash.
Ash can be handled efficiently and effectively through DPCS. Main Components of DPCS are:
Bulker Unloading being the most economical system in industry which uses DPCS for light density (upto 1.6 T/cu.m) for transferring material from Bulker to Storage silo`s. It requires compressed air upto 2 bar and Air solid separation unit at destination Silo.
