Abstract: A steam turbine provided with: a rotor; a plurality of movable blades each of which has a movable blade body and a shroud, and which are circumferentially arranged at intervals; a casing that has a recessed section for accommodating the shroud; fins that form clearances from the outer circumferential surface of the shroud; a stator blade support part disposed on the downstream side of the recessed section; a plurality of stator blades circumferentially arranged at intervals; and an annular partition plate that extends from a recessed section downstream surface toward the upstream side thereof. The casing has formed therein a bypass flow passage that communicates a region radially outside of the partition plate and a region between the stator blades.

Abstract: A coating layer including solely silicon alkoxide or mixed alkoxide of silicon alkoxide and aluminum alkoxide is formed on a surface of a sintered precision-casting core body mainly including silica particles so as to seal holes formed in the surface. As a result, it is possible to prevent the breakage of the core during casting.

Abstract: A method of manufacturing methanol comprising producing a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, allowing reaction of the synthesis gas to take place over a catalyst to produce a crude methanol, separating the crude methanol into unreacted gas and liquid crude methanol, and distilling the liquid crude methanol to separate it into refined methanol and waste water. Carbon dioxide in combustion exhaust gas to be discharged from a reformer is recovered, and that in feeding the carbon dioxide to the upstream side and/or the downstream side of the reformer, part of the unreacted gas is utilized as a purge gas, a portion of which being utilized as a fuel for a combustion device of the reformer, while the balance of the purge gas being utilized as a fuel for other heating sources and/or as an agent for desulfurizating raw gas.
