Ceramic Filter Tubes

HOT GAS FILTRATION

INSULAIRR® ceramic filtration tubes are manufactured by vacuum forming process. These tubes are high strength, rigid, self supporting & designed for excellent filtration of hot flue gasses.

INSULAIRR® ceramic filtration tubes offer a complying with the most stringent regulations and emission standards. Our state of the art rigid micro-porous ceramic filters prevent migration of submicron particles (PM2.5) through the filtration media. High efficiency maintains the ability to remove 96% of all PM10 and PM2.5 Ceramic filters elements can withstand temperatures of up to 1000°C.

ADVANTAGES OVER OTHER HIGH TEMPERATURE FILTER ELEMENTS

PRODUCT WARRANTY

INSULAIRR® Ceramic Filter Tubes are covered under Ceramita Technica (EPE) standard warranty for the quality & specification laid out in its Data Sheets. Ceramita Technica (EPE) ensures that any advice, information or recommendation given are appropriate and correct. The warranty is limited to the quality of material delivered as per specifications mentioned in the Product Data Sheets.

HOW IT WORKS

The Ceramic Filter has a variable number of Microporous Ceramic elements to suit high heat exhaust gas levels. Unlike conventional filtration media the ceramic filter does not flex during operation. This allows sub micron particulates to agglomerate on the surface.

The filtration media is housed above a collection tray or a hopper with an optional screw/ rotary valve discharge. At pre- set intervals the agglomerated PM10 and PM2.5 are discharged off the media by the use of compressed air. The filtration process converts the collected particulates into “balls or plates” which can be easily removed from the collection tray or hopper.

OPERATING PRINCIPLE

The microporous ceramic filter (01) hangs vertically from a header plate (02) within the filter vessel, the header plate separates the filters clean and dirty compartments.
Hot gas is drawn through the filter medium (03) from the outside to the inside.
Submicron particles are collected on the outer surface (04.
The submicron particles are removed from the element by reverse jet pulse (05).
The particles are discharged through the hopper outlet (06) or directly to a tray for collection and disposal.
The filter body is insulated (07) and trace heating (08) is an option.

COMPARISON WITH OTHER FILTRATION SYSTEMS

CYCLONES

This older technology is incapable of removing submicron PM2.5 particles and is ineffective at low gas flows (low boiler load)

ELECTROSTATIC PRECIPITATORS

This technology becomes inefficient when gas flows are variable and units must be oversized to remove submicron material.

BAG FILTERS

Bag filters easily catch fire, and rot when subjected to moisture from Biomass Wood Fired Boilers. Bag flexure results in shorter lifespan, when subjected to PM2.5.
