Abstract: A finishing apparatus 4 has an image forming apparatus 1 for forming an image by an image formation module and a finisher 3 for finishing for a record sheet 2 on which an image is already formed from the image forming apparatus 1. The finisher 3 has a punching unit 5 for punching a hole in the record sheet 2.

Abstract: There is disclosed a wet-processing method for combustion ashes of petroleum fuels, comprising a slurry preparation step of preparing a slurry of the combustion ashes; a metal oxidation step of preparing a slurry containing ammonium metavanadate; a solid/liquid separation step of removing solids from the slurry containing ammonium metavanadate; a double decomposition step for ammonium sulfate, of adding a magnesium compound to an aqueous ammonium sulfate solution recovered from the solid/liquid separation step; and an ammonia recovery step of recovering ammonia from a reaction solution recovered from the double decomposition step. The above metal oxidation step is conducted while controlling an ammonium sulfate concentration of the aqueous solution to 20 to 45% by weight and the temperature of the aqueous solution to not more than 50° C.

Abstract: A process is provided for preparing ammonium metavanadate from the combustion ashes resulting from the combustion of petroleum fuels in a boiler by using the ammonium sulfate and vanadium components in the combustion ash. Water is added to the combustion ash to form a slurry. The solids are removed from the slurry. Ammonia and an oxidizing gas, such as air, oxygen or ozone, are added to the aqueous solution obtained from the slurry to oxidize the vanadium, thereby producing an aqueous solution containing ammonium metavanadate. The ammonium metavanadate is crystallized and recovered from the aqueous solution. Calcium hydroxide or calcium oxide is injected into the aqueous solution and reacts with the ammonium sulfate to produce gypsum and ammonia. This gypsum and ammonia containing solution is flowed down a packed column, where it is counter-currently contacted with air or steam which strips the ammonia out of the solution.

Abstract: The present invention is intended to implement a high-temperature, high-pressure, high-output, high/low-pressure integrated steam turbine provided with a turbine rotor formed as an integral rotor member. It is provided with a high-pressure turbine (3) to which primary steam (20) is supplied, a low-pressure turbine (5) having last-stage turbine rotor blades (47), a turbine rotor (2) formed of an integral rotor member, an integral casing (6), and a downward-exhaust type of exhaust chamber (15); it has a rated power of at least 100 MW; the last-stage turbine rotor blades are rotor blades of an effective blade length of at least 36 inches rotating at 3000 rpm, or are rotor blades of an effective blade length of at least 33.

Abstract: A method is provided for treating ashes from the combustion of petroleum fuels by mixing the combustion ashes with water to produce a slurry; injecting either calcium oxide or calcium hydroxide into the slurry and reacting the calcium oxide or calcium hydroxide with the ammonium sulfate within the ashes to produce a slurry containing gypsum and ammonia; flowing the slurry containing gypsum and ammonia down from the top portion of packed column and air or steam up from the bottom portion of the packed column so that the air or steam strips the ammonia from the gypsum slurry; and separating the gypsum from the resulting ammonia-free slurry using a solid/liquid separator.
