Fly ash pneumatic conveying system M504

dense phaselow-pressurecoal powder

NTE PROCESS developed a unique technology for fly ash conveying (under Filters / ESP, economizers, pre-heater, etc..), storage and fly ash discharge for disposal inside the tanks. NTE PROCESS combined the fluidized membrane technology of its Minijet, a compact and robust transporter suitable for potentially cohesive powders, with Air Assist® patented technology, suitable for controlled injection of air along the conveying lines. This technology allows the system to minimize the air consumption with a dense phase conveying system and consequently limit wear and maintenance. This is a winning technology in all fly ash conveying applications, from coal, fuel oil or biomass even for long distances and high flow rates. The Fly Ash Minijet is also equipped with a special ceramic valve with no rubber seal which can resist to the wear and work up to 400 ° C. The system can be pre-assembled and pre-wired in-house, in our workshop, tested and shipped ready to operate with minimum connections, offering a quick installation and an effective start-up. The long experience acquired in the Heavy Duty industries has also allowed us to develop technologies suitable for any design requirement for fly ash pneumatic conveying using: • Dense phase, pressure and vacuum, with high-pressure air compressors. • Dilute phase, under pressure and vacuum, with low-pressure blowers. • Venturi ejectors for products up to 1000 ° C. Furthermore, a special vacuum system is able to meet the needs of the bottom ash vacuum conveying with sizes up to 3.5 mm.
