Domestic boilers are characterized by low combustion efficiency and are not managed optimally, resulting in high emissions of particulate matter into the atmosphere which makes them one of the main causes of exceeding the emission limits in many Italian and European cities.
The presence of fine dust in the atmosphere causes the impossibility to install industrial filtration technologies in residential applications because these technologies have too high investment, management, energy, and maintenance costs.
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.
