THE POWER TO PROVIDE DUST CONTROL FOR THE ELECTRICITY GENERATING INDUSTRY

An installation completed by Dust Extraction Group Limited at a leading UK power station, involved the use of their Dust ‘X’ ‘CV’ pulse jet tubular bagged filter units. The installation required two of their model CV 10x19 ‘3XL’ filters, with each unit being fitted with 2 x 22 kW integral fan sets.

Both filter units form part of a centralised dust control system with a total air extraction rate of 64,600cuM/hr which serves the Biomass loading facility, extracting dusts generated from loading materials including nut kernels, palm and wood pellets by a 3cuM Komatsu bucket loader onto conveyors, via hopper loaders. Careful consideration was given to the type of filter employed due to the varying characteristics of the products being handled, all of which classified as explosive and having a degree of moisture content.

Purpose designed tipping hoods eliminates the mass migration of airborne dust created during the tipping operation allowing effective dust control of the two hopper loaders and at various points along the two product feed conveyors.

The process plant controls are flexible, providing integration with the clients main operating control system. Stack emission levels from the system are below 5 milligrams/cubic metre.



The extracted dusts from the plant are discharged from the collectors, via rotary valves and screw conveyors, back onto the clients product feed conveyors. This maximises the product throughput and eliminates waste disposal and manual handling.

The clean air discharges from the filter units are policed by two emissions monitors, which continuously check the emissions levels and provide electronic feedback to the customers operating control system.

Access to the filter unit and associated equipment, for maintenance and inspection, is provided by a galvanised staircase with a series of step-off platforms at various levels. Each filter unit is also served by a dedicated compressor unit, to provide the compressed air required for the on-line cleaning operation. A divert system is in place to allow switch over from one unit to another should an emergency situation occur.


Upon completion of the project and final commissioning, the system was subject to an independent inspection by the client’s appointed testing body relating to performance, ATEX and DSEAR standards, after which the plant was accepted and fully operational.
