Abstract: The present invention provides a mobile filter cleaning system allowing movement to a site where dirty filters are located. The filter cleaning system includes a trailer or truck, an air compressor, an aftercooler, an air drier, a filter cleaning station, a compressed air tank, a dust collector, a fan and fan motor, and an airflow verification unit. Along a first fluid communication, compressed air is used to clean dirty filters in the cleaning station and filter cartridges in the dust collector. Along a second fluid communication dirt, liberated from the dirty filter is pulled from the cleaning station to the dust collector by a fan-induced draft. The compressor creates the first fluid communication and the fan creates a second fluid communication.

Abstract: An anchor rail and anchorage system for attaching ceramic refractory materials to a metallic substrate, or casing. Each anchoring rail (3) includes a web (9) and a retention structure. The retention structure of the rails includes a plurality of tabs (13) extending from the web to engage with alignment recesses on the edges of the tiles. The alignment structure on each tile (16) includes a slot (18) formed in each of two opposite sides of the tile (16). A method of building ceramic lined structures includes attaching an anchor rail (3) to a surface of the casing (5), fitting a row of tiles (4) in place with their alignment structures each fitting around the retention structures (13) of the anchor rail, and continuing on with another row of tiles, until a predetermined surface area of the structure is lined with tiles.
