SLEP Furnace (furnace SLEP) is an activation method using water vapor and flue gas (CO2) as the activator, alternately activating method, carbon particles can be from top to bottom in the furnace during movement of mutually shifting movement were mixed uniformly so good activation effect. SLEP furnace is suitable for the production of various kinds of granular carbon, the process conditions are stable, the quality of the product is uniform, the adsorption performance is good, the production of various advanced activated charcoal, big production capacity , the mechanical automation can be realized, the fuel is not needed, long furnace life and so on. So it is widely used in the production of international granular activated carbon. The activation method of the SLEP furnace is a method of activating the steam and flue gas alternately. The SLEP furnace is mainly composed of the furnace body, the…
