摘要： PURPOSE:To make it possible to clean a wafer with high precision by preventing cleaning agent from being mixed with high pressure fluid in the process other than chemicals cleaning process, and by identifying the added amount of cleaning agent precisely. CONSTITUTION:Aside from a high pressure fluid tube 4 in which cleaning agent is added, a bypass tube 13 is installed for supplying only high pressure fluid for a cleaning vessel 1. Except for the chemicals cleaning process carried out by the addition of cleaning agent, the operation is switched to the tube 13 and supplies the high pressure fluid to the cleaning vessel 1.

摘要： PURPOSE:To simultaneously grind and dry coal effectively, by grinding and simultaneously drying coal in a grinder in the presence of hot air fed from a hot air furnace and by controlling an output of the hot air furnace by detecting an outlet temperature of th grinder. CONSTITUTION:Fuel and air are each fed through a fuel supply valve 1 and an air supply valve 2, respectively, into a hot air furnace 3 to burn the fuel, thereby forming hot air, which is fed from an outlet 4 into a loading aperture of a grinder 5 and sent therefrom to the grinder 5 together with coal 6. Here, the coal is ground and simultaneously dried and sent to a classifier 12 and a cyclone 13 to be divided according to its particle size. The air stream containing dust is recycled from the cyclone 13 through a gas blower 14 to the outlet 4 of the hot air furnace. In this process, a thermometer 10 detects an outlet temperature of the grinder and the signal controls the fuel supply valve 1 and the air supply valve 2 to keep the outlet temperature 10 of the grinder within the range of 100-120 deg.C, thereby controlling an inlet temperature 9 of the grinder within the range of 350-400 deg.C.

摘要： PURPOSE:To prevent the adhesion and accumulation of fused slag on the wall of a diffuser section by spurting a gas at ordinary temp. in the tangential direction at the diffuser section in a spouted bed type of coal gasification furnace. CONSTITUTION:A spouted bed type of coal gasification furnace 3 has a gasification section 4 for gasifying coal, a throat section 6 whose inner diameter is smaller than that of the gasification section 4, a diffuser section 7 whose inner diameter is gradually expanded upward and a heat recovery section 8 for recovering heat from the gas. At the diffuser section 7, a recycle gas is spurted in the tangential direction through exhaust nozzles 16a and 16b. The gas spurted descends with rotation along the wall, and joins a produced gas ascending from the gasification section 4 at the throat section 6. So, the wall of the diffuser section 7 is covered with a gas not containing fused slag, and a portion of the hot produced gas comes into direct contact with the wall of the diffuser section 7 to prevent the adhesion and accumulation of the fused slag.

摘要： PURPOSE:To enable to dispose the burning unsuitable refuse without increasing NOX and heavy metals contained in an exhaust gas by a method wherein an incinerating disposal in a fluidized bed burning part is performed by a partial oxidation system under relatively lower temperature, then generated gas is burnt secondarily. CONSTITUTION:A burning unsuitable refuse 1 is introduced into a fluidized bed incinerator 3 after through a feeder 2, then contacted with an air less than a theoretical burning air quantity introduced through an air blast pipe 5 in a fluidized bed 4, processed by the thermal decomposition with a partial burning system under 400-600 deg.C temperature condition. Then, a thermal decomposite gas and finely powdered char moved up toward a chamber tower part 10 direction from a fluidized bed 4 are contacted with a powdered desalting agent such as CaCO2 and the like supplied through a line 11A, then desalted. Further, the thermal decomposite gas treated by desalting is secondarily burnt under the existence of the secondary air supplied through a line 20. Thereby, the burning unsuitable refuse can be disposed without increasing NOX and heavy metals.

摘要： PURPOSE:To obtain a necessary temperature in the gas in a heat recovery section by providing a combustion catalyst layer on the upstream side of exhaust gas in an exhaust heat recovery section and supplying a fuel into the combustion exhaust gas from the upstream side to burn the fuel with the residual oxygen and heating the combustion exhaust gas to a high temperature. CONSTITUTION:The temperature of the raw material flowing through a reaction tube 4 which is provided at a radiation heat transfer section 3 is heated to about 800 deg.C due to the temperature in a furnace which has reached 1000 deg.C obtained by burning a gas fuel by means of the main burner 2 provided in a heating furnace 1. The combustion exhaust gas leaving the radiation heat transfer section 3 is led by natural draft to convection heat transfer sections 5 and 6. In order to cover the shortage in the retained colory in the exhaust gas required for recovery of the exhaust heat, an auxiliary fuel is supplied from an auxiliary fuel supply header 7 on the upstream side of the convection heat transfer sections 5 and 6 to pre-mix the auxiliary fuel with the exhaust gas, and then the auxiliary fuel is made to react with O2 gas that remains in the exhaust gas in the combustion catalyst layer 8 to heat uniformly the exhaust gas to 1200 deg.C with the heat produced by the said reaction.

摘要： PURPOSE:To gasify even pulverized coal formed during grinding to raise the gasification efficiency of ground coal, by feeding the ground coal obtained by grinding row material coal to the gasification furnace of a fluidized bed type in the form of a slurry to gasify the coal. CONSTITUTION:Ground coal obtained by grinding raw material coal with grinding equipment 1 is sent to slurry mixing and preparing equipment 4 to be mixed therein with a slurry forming medium (e.g., petroleum pitch, water) sent from a resorvoir 2, forming ground coal slurry. The formed slurry is fed via a slurry feeder 5 to a gasification furnace of a fluidized bed type 6 to be gasified at a high temperature. Further, the above-mentioned slurry can be also prepared by feeding the raw material coal and the slurry forming medium to e.g. equipment such as a wet mill for the grinding of coal and the simultaneous mixing of the two components.

摘要： PURPOSE:To make it possible to make molten slag flow down from a gasifying chamber to a slag granulating chamber without solidifying the molten slag utilizing heat energy of the molten slag by forming a projection from the bottom of the wall of a gasifier on the end of an opening of a slag passage on the bottom of the wall. CONSTITUTION:When coal and an oxidizing agent are fed from each gas burner 18 into a gasifying chamber, a part of coal is oxidized and the inside of the gasifying chamber is heated to about 1,500-1,700 deg.C to gasify remaining coal. Ash in the coal is converted into molten slag 26, which is stored on the bottom side of a gasifier 10. The surroundings of a projection 32 are heated both by heat transfer from the molten slag 26 and radiant heat from the gasifying chamber 20 and is kept and the m.p. (about 1,400 deg.C) of the molten slag 26. When the amt. of storage of the molten slag 26 exceeds a specified amt., the molten slag 26 flows down along a groove 38 from an orifice 36 into a communication path 34. In this case, the molten slag is not brought into contact with the wall surface of a low-temp. slag tap 28 and flows into a slag granulating chamber 22 without solidification. Therefore, no clogging of the slag passage occurs.
