Title:
CARBONIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/175053
Kind Code:
A1
Abstract:
The present invention is provided with: an inner tube (112) through the interior of which flows low-grade charcoal (1); a supply feeder (113) that supplies the low-grade charcoal (1); heating means (111, 117, 118, 119) that heat the low-grade charcoal (1); a shooter (116) that sends out carbonization gas (3) and generated carbonized charcoal (2); a reference gas supply source (115) that adds a reference gas (4) such as nitrogen gas to the carbonization gas (3); a gas concentration measurement device (131) that measures the concentration (Cs) of the reference gas (4) and the concentration (Cc) of carbon dioxide in the mixed gas of the reference gas (4) and the carbonization gas (3) from the shooter (116); and a computation control device (130) that, on the basis of the concentrations (Cc) and (Cs), the supply flow rate (Fs) of the reference gas (4), and the supply weight (Wo) of the low-grade charcoal (1), calculates the amount (Fc) of carbon dioxide generated, determines the carbonization fraction (Dt) of the low-grade charcoal (1) from a map that has been input ahead of time, and controls a heating means (118a) in a manner so as to result in a target carbonization fraction (Dr).
