Dust Control System - Energy from Waste Plant

Impact Air Systems were selected to design and install numerous air system components and a centralised dust control system at an energy from waste plant in Hull, UK. The power station will be processing typical SRF/RDF material to ensure that it meets a very tight specification allowing the finished material to be fed into a gasification process where it will be burned as a fuel to produce electricity.

Impact’s experience and expertise were relied upon to provide fans and a ductwork circuit that would remove dust effectively and efficiently from numerous collection points throughout the plant. Included at the point of lights discharge are mechanical pre-separators which work to prevent any oversized items such as plastic bags or fibre from entering the fan circuit, dust system or filter.

The central dust extraction system connects a total of 39 collection points using galvanised mild steel spiral wound ductwork.

The three final dust extraction header ducts serving all the points will connect to the filter using an ATEX certified isolation damper. The dust filter will be approximately 500m2 and will be fully automatic tubular bag reverse jet filter and will be rated for approximately 72,000m3/h total air volume.

The filter unit will remove the dust particles from the airstream and discharge them via a trough hopper into a single Ø250mm screw conveyor and 400mm diameter rotary valve
for depositing into the dust briquetting system.
