Mecgale specializes in complete line of bottom ash handling systems. Bottom ash, from boiler can be conveyed, by using either dry system through dense phase pneumatic conveying, or wet system utilizing scrapper conveyor and water impounded hopper. Conveying system is designed after conducting in-depth study of the plant and client’s requirements.

Dry bottom ash from the after cooler of boiler is collected in the water-cooled surge hopper. Ashcon placed underneath the surge hoppers, conveys the material. Ashcon is designed to convey abrasive and irregular sized material at temperature even up-to 450 °C. For Clinker ash, Clinker grinder breaks larger lumps into small size and continues to deposit ash and broken clinker into the Ashcon for further conveying. Bottom ash is transported at low velocity through enclosed pipeline to storage silo, thus reducing pipeline erosion. This system does not require water, thereby negates all water related difficulty and problems.
