Title:
HIGH TEMPERATURE GASIFYING PROCESS WITH BIOMASS AND SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/063206
Kind Code:
A1
Abstract:
High temperature gasifying process with biomass includes feeding, carbonization, powder making of charcoal, transporting of powdery charcoal and gasifying in gasifier, wherein carbonization is carried out in the carbonization furnace for pyrolysis of biomass with the heat released by the direct combustion of additionally provided combustible gas and oxygen, the product of carbonization is pyrolysis gas and charcoal. The temperature in the carbonization furnace is controlled at 400~600℃through adjusting the amount of oxygen, the molar number of combustible gas is greater than 1 and less than 5 based on that the molar number of combustible gas is 1 when it is completely combusted with oxygen. The temperature of the flame at the nozzle of the carbonization furnace is controlled at 1800~1200℃ through adjusting the amount of additionally provided combustible gas entering into the carbonization furnace. Powdery charcoal is formed through reducing the temperature of charcoal, reducing pressure, powder making, increasing pressure and fluidization, and the powdery charcoal is sent to gasifier through adjusting the transportation amount of the pyrolysis gas. The system for performing the process includes a carbonizing furnace, a powder-making system and so on.
