Biomass Ash - Grupo Modelo Brewery, Zacatecas Mexico

IN BRIEF Problem: Large brewery wishes to recycle waste grain and malt from the brew process for the production of electric power. Handling the biomass ash cleanly and economically was required. Solution: Macawber pneumatic conveying systems were used to convey boiler bottom ash and fly ash away to storage. The biomass is dried and transferred to a boiler where it is burned with #6 oil. The biomass fly ash is gathered from four electrostatic precipitator (ESP) hoppers and pneumatically conveyed to an ash silo. The bottom ash is crushed and transferred a short distance via customer's mechanical conveyor to a pneumatic conveyor where it is transferred to an ash silo for truck loading.
