Title:
汚泥燃料化装置
Document Type and Number:
Japanese Patent JP5300237
Kind Code:
B2
Abstract:

To provide an apparatus that can not only greatly reduce the use amount of fossil fuel but can stably carbonize and convert sludge as the main object of the process into fuel with a small amount of assistant fuel, avoid decrease in the boiler efficiency, can be stably driven and greatly decrease the running cost.

The apparatus for converting sludge into fuel is characterized in that: the apparatus includes a pyrolytic carbonization furnace 6 for subjecting sludge to a pyrolytic carbonization process to generate a pyrolysis gas and a carbonized product and a combustion furnace 7 for combusting the pyrolysis gas generated in the pyrolytic carbonization furnace 6; the combustion exhaust gas generated in the combustion furnace 7 is used as a heat source of the pyrolytic carbonization furnace 6; and a dust recovery device 21 recovering dust in the exhaust gas is provided in a combustion exhaust gas line 14a between a combustion furnace exhaust gas exit of the combustion furnace 7 and the pyrolytic carbonization furnace 6.
