Title:
DEWATERING/WASHING PROCESS-ASSOCIATED SYSTEM FOR PRODUCTION OF FUEL HAVING ASH PRODUCING COMPONENT REMOVED FROM BIOMASS IN LOW TEMPERATURE CONDITION
Document Type and Number:
WIPO Patent Application WO/2019/194336
Kind Code:
A1
Abstract:
The present invention relates to a system for production of boiler fuel in which ash producing components are removed from fuel. More specially, the present invention relates to a system for production of fuel having ash-producing component removed for boilers, wherein ash-producing components, which cause adverse effects such as fouling, slagging, high-temperature corrosion, clinker generation, etc. on a heating surface such as in reactor walls, heat exchangers, etc. upon the operation of a boiler with herbaceous, woody, and algal biomass, are removed by physical and chemical methods, and after the removal, the solid-phase components are utilized as solid fuel for firing or co-firing while the liquid-phase components including ash-producing components are subjected to water treatment using a method including acid treatment, alkali treatment, hydrothermal treatment, membrane filtration, ion exchange, flocculation, adsorption, and centrifugation.
