Title:
METHOD FOR OPERATING A SYSTEM FOR PRODUCING BIOETHANOL
Document Type and Number:
WIPO Patent Application WO/2010/057554
Kind Code:
A3
Abstract:
The invention relates to a method for operating a system (1) for producing bioethanol, wherein organic waste products of the production process, particularly DGS and DDGS, are combusted and the useful heat is fed back into the system (1) itself. The combustion process takes place in a fluidized bed oven (2). All areas (9, 11) in which the combustion process takes place have sufficient heat removed that the melting point of the ash of the waste product, particularly 70°C, is not exceeded at any point. In this manner, a fine-grained ash forms and largely mixes into the fluidized bed (9) and is easily disposed of. The useful heat is obtained partially from the flue gas arising from the combustion, and partially from the heat extracted from the combustion process for maintaining the maximum temperature.
