Abstract: Provided are a slag crusher, a gasifier, an integrated gasification combined cycle, and an assembly method of a slag crusher that can ensure the strength of a guide rod. The slag crusher includes: a porous member screen; a spreader that is reciprocated in a predetermined direction along a top surface of the screen and crushes the slag accumulated on the screen; and a guide rod having an axis line along the predetermined direction, is connected to the spreader, and restricts a moving direction of the spreader, the guide rod has a spreader-side member connected to the spreader and a shaft member connected to the spreader-side member, the spreader-side member and the shaft member are connected by butt welding in the axis line direction, and the spreader-side member and the shaft member have the same shape of cross sections orthogonal to the axis line direction at a butt welding position.

Abstract: A gasification unit includes a gasifier configured to gasify a carbon-containing solid fuel; a pressure vessel housing the gasification furnace; a pressure holding section that is to be filled with a pressurizing gas and is provided between the gasifier and the pressure vessel; a pressurizing gas supply device configured to supply a pressurizing gas to the pressure holding section; pressure equalizing pipes by which the inside of the gasifier is communicated with the pressure holding section; a pressure difference detection and estimation device configured to detect or estimate a pressure difference between a first pressure on the gasifier side and a second pressure on the pressure holding section side; and a control device configured to control the pressurizing gas supply device such that the second pressure is higher than the first pressure based on a detection or estimation result of the pressure difference detection and estimation device.

Abstract: A slag crusher includes a screen provided so as to intersect a falling direction of a slag and having openings; at least two spreaders disposed opposite from one another on the screen; and a spreader moving unit configured to support the spreaders and move the spreaders in a direction vertical to the opposing faces of the spreaders. Each spreader includes projections and a lower projection so as to face the other spreader. In a state in which the lower projection is closest to the other spreader, the lower projection does not come into surface contact with the opposed lower projection, and a distance between the opposing lower projections is smaller than an opening dimension of the openings of the screen across a width direction of the spreaders.

Abstract: A method for controlling a gas turbine power plant, a gas turbine power plant, a method for controlling a carbon-containing fuel gasifier, and a carbon-containing fuel gasifier that can keep constant the amount of heat generated from a synthetic gas produced by the carbon-containing fuel gasifier. The gas turbine power plant includes a coal gasifier including a coal gasifier unit that gasifies a fuel containing carbon to produce a synthetic gas and a water-cooled wall duct disposed on the coal gasifier unit and to which a coolant, i.e., water, is directed; a gas turbine combustor that combusts the synthetic gas to produce combustion gas; a gas turbine rotated by the combustion gas produced by the gas turbine combustor; and a generator that generates electrical power. The amount of fuel fed to the coal gasifier is controlled depending on the amount of heat absorbed by the coolant directed to the water-cooled wall duct.

Abstract: Disclosed in the present invention is a process for preparing a (meth)acrylic acid-based polymer having a stable quality and suitable as a dispersant for cement. That is, the present invention provides a process for preparing a (meth)acrylic acid-based polymer, comprising the steps of the stage 1 of introducing (meth)acrylic acid and a polyalkylene glycol monoalkyl ether at a molar ratio in the range of 3:l to 50:1, subjecting them to an esterification reaction in the presence of an acid catalyst and a polymerization inhibitor and deactivating the acid catalyst with an alkaline agent in order to obtain an esterification product containing a (meth)acrylate and (meth)acrylic acid residues and the stage 2 of copolymerizing the (meth)acrylate and the (meth)acrylic acid residues at a pH value in the range of 1.5 to 3.5.

Abstract: An organic hydroxyl compound is reacted with polyphosphoric acid under such conditions that the ratio, as defined by formula (1), has a value exceeding 3.2; and phosphorus pentaoxide is added to the reaction product thus obtained in such an amount that the ratio, as defined by formula (1), has a value in the range of from 2.8 to 3.2: ##EQU1## If necessary, the obtained reaction product is deodorized by the removal of the organic hydroxyl compound unreacted therefrom. The process does not give any product of high-viscous gel and therefore enables the industrially easy manufacture of a phosphoric monoester having an extremely high purity, a lowered orthophosphoric acid content, and a good odor.
