The present invention is provided with: a reference gas supply source that adds a reference gas that is a noble gas to a carbonization gas; a combustor that combusts the mixed gas of the carbonization gas and the reference gas and sends out an inspection gas; a gas rheometer that measures a flow rate of the inspection gas; a gas concentration measurement device; and a computation control device that determines the flow rate of the reference gas (noble gas) in the mixed gas from the concentration of reference gas, determines the amount of carbon component generated in the carbonization gas, determines the carbonization fraction of carbonized charcoal from the concentration of the carbon component in low-grade charcoal, the amount of carbon component generated, and the weight of supplied low-grade charcoal, and controls a valve in a manner so that a target carbonization fraction results. |

1. A pyrolysis apparatus, comprising:
a furnace main body in which a solid organic material flows; organic material supply means for supplying the organic material into the furnace main body; heating means for heating the organic material in the furnace main body; sending-out means for sending out a solid pyrolysis product and a pyrolysis gas resulting from the heating and pyrolysis in the furnace main body; standard gas supply means for adding a standard gas including a rare gas to the pyrolysis gas; test gas production means for sending out a test gas formed by completely combusting a mixture gas of the pyrolysis gas and the standard gas sent out of the sending-out means with air for complete combustion; test gas flow amount measurement means for measuring a flow amount Fi per unit time of the test gas sent out of the test gas production means; gas concentration measurement means for measuring a concentration Cc of carbon dioxide and a concentration Cr of the standard gas in the test gas; and arithmetic control means for
calculating a flow amount Fr per unit time of the standard gas in the mixture gas completely combusted by the test gas production means by the following formula (1) on the basis of the flow amount Fi measured by the test gas flow amount measurement means and the concentration Cr measured by the gas concentration measurement means,calculating a generated amount We per unit time of carbon components in the pyrolysis gas sent out of the sending-out means by the following formula (2) on the basis of a flow amount Fs per unit time of the standard gas supplied from the standard gas supply means to the pyrolysis gas, the flow amount Fr calculated by the following formula (1), the flow amount Fi measured by the test gas flow amount measurement means, and the concentration Cc measured by the gas concentration measurement means,calculating a pyrolysis ratio Dt of the pyrolysis product sent out of the sending-out means by the following formula (3) on the basis of a weight Wo of the organic material supplied per unit time into the furnace main body by the organic material supply means, the generated amount We calculated by the following formula (2), and a concentration Cg of carbon components in the organic material inputted in advance, andcontrolling the heating means to make the pyrolysis ratio Dt equal to a desired pyrolysis ratio Dr:
Fr=Fi×Cr (1),Wc={(Fi×Cc)/Fr}×{(Fs/22.4)×12} (2), andDt=(Wc/Cg)/Wo (3). |
