Fly Ash Transporting System
Vacuum Conveying System
We provide Vacuum based fly ash conveying system to extract and convey the fly ash collected in the Air Pre Heater hoppers, Duct hoppers and Electrostatic Precipitator hoppers of AFBC, CFBC & PF type Boilers. The vacuum required for the system is created by Vacuum Pumps. A Buffer hopper / Intermediate surge hopper / Silo provided with dust collector cum bag filter unit will separate the fly ash from the conveying system, for onward pressure conveying to storage silo/ unloading system. As a further option, slurrification system can also be offered in combination to the vacuum system for pumping the fly ash slurry to ash dyke area. This offer redundancy & flexibility to the system.
Pressure Conveying System
We provide positive pneumatic Dense / Lean Phase pressure conveying system for conveying the fly ash collected in the Air Pre Heater and Electrostatic Precipitator hoppers of AFBC, CFBC & PF type Boilers. Each fly ash hoppers is provided with ash transport vessels, ash intake / discharge valves to collect and transport the fly ash to storage silos for disposal / utilization.
