Provided is a coal gasifier enabling a reduction in size of a shift reactor by generating hydrogen-rich gasified coal gas. In a coal gasifier (G) generating gasified coal gas by a gasification reaction proceeding in a furnace fed with a gasifiable raw material, such as coal, and a gasifying agent, at least one of water and steam is fed to the furnace as a material accelerating a hydrogen-generating reaction that proceeds simultaneously with the gasification reaction.

Coal gasifier

A bin system and a char recovery unit are provided with: a bin for storing char; three char discharge lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to discharge the char into the bin; four switching lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to feed the char stored in the bin; and assist gas feed units as assist devices for assisting the flow of the char that falls with the force of gravity through the char discharge lines. This allows for equipment downsizing.

Bin system and char recovery unit

An integrated coal gasification combined cycle facility is provided that can prevent a reduction in power generation efficiency even when low-grade coal having a relatively-high moisture content is used. Included are: a gasification section that gasifies supplied coal; a gas power generation section that generates power by using gas supplied from the gasification section; a steam power generation section that generates power by using the heat of exhaust gas discharged from the gas power generation section; and a coal drying unit that dries the coal by using exhaust heat discharged from the steam power generation section and that supplies the dried coal to the gasification section.

The amount of high-temperature steam supplied from external equipment is reduced. Provided is a hydrogen production system () including a reactor () that allows a humidified process fluid output from a humidifier () to react in the presence of a catalyst to transform carbon monoxide in the process fluid into carbon dioxide; a second channel (B) through which the high-temperature process fluid that has reacted in the reactor () flows; a circulation channel (C) through which excess water in the humidifier () is circulated; and a first heat exchanger (), disposed at an intersection of the circulation channel (C) and the second channel (B), for heat exchange between the high-temperature process fluid that has reacted in the reactor () and the fluid circulated through the circulation channel (C).

The present invention is directed to a method for forming a thin film on a substrate by the use of a glow discharge plasma which comprises generating a magnetic field in a direction which crosses an electric field for discharge at right angles and fluctuating the magnetic field. The present invention is also directed to an apparatus for practicing the above method, which apparatus is composed of a reaction vessel, means for reducing the pressure in the reaction vessel and means for introducing the feed of reaction gases to the reaction vessel, electrodes for discharge disposed face to face in the reaction vessel, a power source from which a voltage for causing a glow discharge is fed to the electrodes for discharge, a coil surrounding the electrodes for discharge, for generating a magnetic field in a direction crossing at right angles to an electric field generated between the electrodes for discharge, and an AC power source for generating a magnetic field fed to the coil, whereby a thin film is formed on a base plate supported outside the range of the discharge electric field and in parallel with the direction of the electric field.

A laminated iron core of an electric device is prepared by stamping a strip having a width smaller than an outer diameter of the laminated iron core to form iron core discs having one or more straight edges and also to form segmented circular pieces from excess fragments of the strip and processing the iron core discs to form iron core ring plates having straight edges and assembling the iron core ring plates and the segmented circular pieces to form the laminated iron core.
