Many Italian and European cities faces issues related to excessive particulate emission in the atmosphere,
caused by the use of domestic boilers, which are characterized by low combustion yields and the high emission
of particulates. The proposed invention comprise a wet filter consisting of a generator of droplets suitable for the
separation of fine powders transported by a gaseous stream. Deployed on the output of the particulate-emitting
device, such as a biomass boiler, it allows filtering the particulate contained in the exhaust gas, with extremely high
efficiency.

Applications

Plants, including domestic boilers, requiring higher filtration ratio, without having to install an industrial filter

Advantages

  • low energy consumption
  • possibility of tailoring
  • high level of separation efficiency
