The ABF 8/28: a new ashing furnace

World Coal,

The ABF 8/28 is a powerful and robust ashing furnace, which features an integral afterburner. The ashing furnace therefore comes equipped with  additional features to those of standard ashing furnaces. Typical applications for the ashing furnace include residue analysis, the burning of samples to constant weight and also the recovery of precious metals. As these processes can lead to unpleasant smoke and odour, the ABF 8/28 is fitted with a fan assisted pre-exhaust afterburner to combust the smoke further before exiting the chimney. The afterburner is rated for 40 g carbon per ashing load.

The recycling of valuable materials, such as plastic insulation of cables, paints, polymer-based metal blanks or plastics from PCBs are further applications for the ABF.
