Abstract: PROBLEM TO BE SOLVED: To increase generation efficiency through low-cost and simple constitution and realize gasification power generation even by fuel having low and stable NOx in exhaust gas. SOLUTION: A gasification power generating system comprises a gasifying means 10 to generate high temperature gasification generation gas by reacting fuel 17 and a gasifying agent 16 with each other; a generating means 20 to effect power generation by using energy generated by burning high temperature gasification generation gas generated by the gasification means 10; and a preheat means 30 to preheat the gasifying agent, fed to the gasifying means 10, to a self-ignition temperature, for example, approximate 1000 deg.C. The preheat means 30 increases a temperature of air fed in the gasifying means 10 to a high temperature of approximate 1000 deg.C when, for example, fossil fuel such as coal is used as the fuel 17.

Abstract: PURPOSE:To improve the utilizing rate of heat accumulating material during the operation of a heat exchanger and permit the distribution of voids, generated in accordance with the change of the phase of the heat accumulating material, into respective parts of a vessel by constituting an area, in which a heat transfer tube makes contact with the heat accumulat ing material in the vessel, is constituted so as to be spiral. CONSTITUTION:Heat accumulating material 12 is sealed into a vessel 11 while a first spiral heat transfer tube 13a, penetrating the vessel 11 lengthwisely, and a second spiral heat transfer tube 13b, pairing with the first spiral heat transfer tube 13a, are provided in the vessel 11 respectively. In this case, the first and second spiral heat transfer tubes 13a, 13b are formed so that a distance between the first and second spiral heat transfer tubes 13a, 13b and another distance L between the heat transfer tubes and the internal surface of the vessel 11 become given values. In above-described constitution, medium to be heated flows through the spiral heat transfer tubes 13a, 13b from the side of sunshine to the side of shade and the heat accumulating material at the side of shade is heated by the medium to be heated, whose temperature is increased, and, therefore, the utilizing rate of the heat accumulating material 12 may be increased. On the other hand, the distance L is kept in the vessel 11 and, therefore, initial solidified parts A appear between the spiral heat transfer tubes 13a, 13b and the like whereby voids are distributed in respective parts of the vessel 11.

Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent load on the environment and further supply power to meet demand and store surplus power in the form of fuel. SOLUTION: The system is constituted of a power station 1, a water decomposing device 3 or a device which forms fuel from hydrogen produced in the water decomposing device 3, and an auxiliary power generating device 6 which uses hydrogen or fuel to generate power. When there is little demand for power, the water decomposing device 3 is operated using energy from the power station 1 and thus produced hydrogen or fuel is stored. When there is a great demand for power, together with the power station 1, the auxiliary power generating device 6 is operated using the hydrogen as fuel or the fuel to generate power. The system may be constituted of a water decomposing device, a fuel producing device, a generator and a carbon dioxide separator to maintain the material balance substantially in a closed system. Further, a sea water decomposing device applicable to the system may be installed to prevent by-products harmful to the environment from being produced.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a facility and permit continuous operation by a method wherein a nozzle, injecting cooling medium into water in an ice making device vessel, and a perforated plate, on which suction holes for supplying the cooling medium, injected by the nozzle provided in the cooling medium, to a cooling means, are provided. SOLUTION: Anti-freeze is injected through an anti-freeze nozzle 5 and the anti-freeze is taken out through an outlet port nozzle 8. In a reserving unit 4, a perforated plate 12 is installed in parallel to a baffle plate 7 and a plurality of suction holes 11, for passing anti-freeze which has flown into the reserving unit 4, are formed. The antifreeze, passing through the suction holes 11 of the perforated plate 12, is taken out through the outlet port nozzle 8 and is cooled by a refrigerating machine, further, is injected into an ice making device vessel again from the anti-freeze nozzle 5 whereby a part of the anti-freeze, which carries bubbles and whose flow speed is high, is eliminated. According to this method, freezing, clogging and the like of downstream instruments due to the mixing of water or ice into the anti-freeze can be prevented and the miniaturization of a facility can be contrived.

Abstract: PROBLEM TO BE SOLVED: To provide a method wherein deposition of carbon can be suppressed and a fuel cell can be operated for a long time stably, when methanol, ethanol or dimethyl ether is supplied as its fuel to a fuel electrode of the fuel cell. SOLUTION: A fuel cell contains electrolyte, a fuel electrode and an oxidizer electrode to put the electrolyte mentioned above between, and an operating temperature is set at 550-750 deg.C. In this case, a mol mixing rate for water and fuel is set for, (1) When fuel containing methanol is used, 0.250+0.287 P-1.08×10 P P , (2) When fuel containing ethanol or dimethyl ether is used, 1.500+0.574P-2.15×10 P P , (In the above, P is an operating pressure for each fuel cell (atm)), and the fuel is supplied to the fuel electrode of this fuel cell.
