“…Even 99.99% in terms of efficiency can be achieved [5]. This is the reason, why they are used in industry for dust treatment so frequently [4][5][6][7]. The limitation in filter applications lies in the maximum allowable temperature given by used material of the filter bag or candle [4,6].…”

“…The negative effects of both fractions of PM -PM 2.5 and PM 10.0 on the human health are already known and well described [1][2][3][4]. PM poses more health risk when comparing to common air pollutants like carbon monoxide and even ground level ozone [1] created by photochemical oxidation reactions between nitrogen oxides (NOx) and volatile organic compounds (VOC).…”

“…This is the reason, why they are used in industry for dust treatment so frequently [4][5][6][7]. The limitation in filter applications lies in the maximum allowable temperature given by used material of the filter bag or candle [4,6]. Temperature upper limit for natural fibres is about 90°C and fabrics made from glass and synthetic fibres are usable up to 230-260°C during continuous operation -PAN (125°C), PES (140°C), PPS (180°C), PI (240°C), glass (260°C) [4].…”

Fabric filters are made from the flexible material, so this makes them less susceptible to thermal shocks, rough handling and excessive temperature, which can lead to premature material damage [6].…”

In this paper, the results of the 34 day test of particulate matter (PM) removal from air stream emerging from granulated fertilizers production (NPK and mixed ammonium sulphate fertilizers) are presented. Operators of the plant wanted to replace older wet scrubber preferably with filter bags which can provide waste less operation of the technology, because separated PM can be reintroduced to the production. Because of the assumption of the sticky and problematic deposits formation on the filter bags that could increase excessively the pressure loss, test on the pilot unit with 15 filter bags with pulse-jet bags cleaning was carried out. During the test, various technological conditions were tested. Temperatures, stream humidity, pressure loss of bags and inlet and outlet PM concentrations were monitored. It was found that dry cleaning of this air stream is problematic as expected, but feasible. Filter bags were absorbing considerable amounts of water from the dust stream (fertilizers are granulated by steam and water). This fact leads to hard removable deposit formation and increased pressure loss, but if the stream was preheated by a small natural gas burner, the deposition creation was reduced. According to results of the long term test, recommendations for the technological conditions for full scale bag filter were provided for given type of technology and production.
