WET FILTER FOR FINE PARTICULATE

Biomass combustionDomestic boilersFine particulateIndustrial boilers

Introduction

The invention relates to a wet filter, to be deployed both on industrial and domestic boilers, for the separation of fine particulates present in the gases deriving from the biomass combustion.

Technical features

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.

Possible 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.
