Hot Gas Filtration

Filter Design's systems usually involve the supply and installation of a flue gas treatment plant which is based around a bag filter system to remove particulate from the air streams.

As well as this function the system is often designed to treat the flue gas to ensure emissions are meeting environmental emission standards.

Our recent Projects

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
