Abstract

Recently, the sludge increase dramatically with the economics development, this disposal is big issue. Moreover, the electric consumption also increases with the economics development. Although a new energy development such as fuel cell is promoted about the problem of the power consumption, the correspondence of the disposal of the sludge is promoted hardly. Therefore, we propose the gasification system for which the sludge gasify by molten salt. Moreover, this gasification gas is used as fuel gas of MCFC. This paper elucidates the fundamental characteristics of the gasification of the sludge. The crucible filled with the molten salt is installed in the reaction vessel, and can be set to an arbitrary temperature and the gas atmosphere. The sludge is supplied into the molten salt, and is gasified. The chemical composition of the gasification gas is analyzed by HC meter, SOx meter and the gas chromatography. As a result, although the gasification of sludge by molten carbonate can generate CO and H2 as same as the chemical equilibrium value, the molten carbonate was not able to absorb SOx enough. HC causes carbon deposition at the exhaust pipe because the moisture of the sludge is a few. Consequently, the sludge can be expected as the fuel for the gasification which uses the molten salt.
