摘要： PROBLEM TO BE SOLVED: To enhance the total heat utilization rate of a waste incineration heat utilization system, say, a power generating system using heat produced by the incineration of waste, by reducing the amount of heat required for preventing exhaust gas coming from its waste incinerator from becoming white fume. SOLUTION: In a waste incineration heat utilization system, which has at least an incinerator 1 for incinerating wastes, a boiler 2 for producing steam by use of the heat of incineration of the incinerator, and an exhaust gas reheater 6 which, in order to prevent exhaust gas from the incinerator from becoming white fume, heats the exhaust gas while using a part of the steam as a heat source, a water eliminator 9 for eliminating water in the exhaust gas is placed on the upstream side of the exhaust gas reheater 6 to lower a white fume preventing temperature through the elimination of water in the exhaust gas so as to reduce the amount of heat (amount of steam) required for reheating of the exhaust gas. Preferably, a coolant in which heat is stored in ice by a refrigerator 12 by use of night power is circulated by the water eliminator 9 to eliminate the water through condensation.

摘要： PROBLEM TO BE SOLVED: To prevent a heat transfer pipe from being corroded by chlorine contained in solid fuel by a method wherein a heat energy generated under combustion of solid fuel attained through dehydration of combustible waste materials, reduction in volume and its solidification is converted into electrical power and recovered. SOLUTION: Powder type solid fuel obtained through dehydration, reduction in volume and solidification of combustible waste material is fed into a boiler 1 together with combustion air so as to form a flame 4. An inner wall of the boiler 1 is provided with water pipes 5 for generating steam, a steam turbine is driven to generate electricity. In this case, a steam superheater 6 where the temperature shows the highest value is arranged at the bottom surface of the boiler 1 and then a incombustible layer 18 composed of gravels is arranged on the steam superheater 6.

摘要： PROBLEM TO BE SOLVED: To attain high power generating efficiency by a method wherein a waste power generating device is provided with a feed water heater, heating feed water for a heat recovering boiler employing fuel gas, obtained by a thermal decomposing device, as fuel therefor, is provided. SOLUTION: Combustible waste 1010 is burnt in an incinerator 1000. Combustion gas 10 provides a superheater 3000 and a heat recovering boiler 2000 with heat and, thereafter, is released into atmosphere through a chimney 1200. On the other hand, boiler feed water 40 is evaporated in the heat recovering boiler 2000 and becomes steam. The temperature of saturated steam, generated in the boiler, is elevated in a heater 3000 and the saturated steam becomes supersaturated steam 20. The supersaturated steam 20 drives a steam turbine 4000 and generates electricity by a generator 5000. The boiler feed water 40 is heated by a feed water heater 8000 before being supplied into the heat recovering boiler 2000. The feed water heater 8000 heats the boiler feed water 140 utilizing fuel gas, produced by a plastic thermal decomposing device 9000. Calorific power, retained by exhaust gas, is utilized effectively in such a manner whereby a high power generating efficiency can be achieved.

摘要： PROBLEM TO BE SOLVED: To melt ashes and reduce disposal cost by injection an oxidizing agent into the ashes discharged from an incinerator for combustion, and attaching an ash-melting furnace to a part of the incinerator. SOLUTION: The refuse discharged from a hopper 1 is conveyed by a refuse supply machine 3 and loaded on a stoker 4a and moved to a stoker 4b. The refuse, which is moved on the stoker 4b is moved by the stoker 4b while it is being burnt and then the refuse is moved on a stoker 4c. The refuse, which is moved on the stoker 4c, enters the final combustion stage and is turned into ashes and discharged into an ash melting furnace 6. The oxygen or oxygen rich air from an oxidizing agent-manufacturing device 5 is blown into the ashes discharge into the ash-melting furnace 6 so that the ashes may be burnt and molten by remaining combustion heat of unburnt carbon contents in the ashes and ash itself. The molten ashes are collected into an ash molten article vessel 7. The exhausted gas generated during this work, joins into an exhaust gas treatment system of an incinerator 2 so that they may be treated together with the exhaust gas of the incinerator 2.

摘要： PURPOSE: To contrive to realize the energy saving of oil converting refining device of waste plastics and a low cost of formula oil. CONSTITUTION: The waste heat recovering type plastic oil converting refining device and power generating system consists of a plastic oil converting refining device 1, an engine 2, a generator 3, a waste heat recovering vessel 4, a steam superheater 5, an incinerator with steam generating device 6, a steam turbine 7 and a generator 8. Thus, the introduction of the heat necessary for thermal decomposition from outside becomes unnecessary and energy-saving effect is realized. Further, due to the system, in which heat energy in waste heat is utilized in cascade, both electric power and heat for thermal decomposition are obtained simultaneously. Furthermore, since the oil converting refining device of waste plastics is combined with refuse power generation, both the systems can efficiently be operated at all times, even when throughputs of waste plastics and of combustible refuse do not thermally coincide with each other. In addition, low boiling point gas, which generates in the thermal decomposition of the waste plastics, can effectively be utilized.

摘要： PURPOSE:To increase the heat-conducting performance of a heat pipe and to prevent the drying-out phenomenon of the heat pipe by a method wherein a highly heat- generating electronic component is arranged and installed so as to be close to the side of the heat-dissipating part of the heat pipe. CONSTITUTION:Fin 7 for heat-dissipating use are fixed to one end of a heat pipe 1 so as to be perpendicular to the heat pipe 1. The other end is fitted to the inside of a fitting groove 8 which has been formed in a face with which two heat-generating sheets 2 are faced. A wiring board 4 whereon heat-generating electronic components whose heat must be dissipated have been mounted is arranged on one face of one heat-receiving sheet 2 so as to be in parallel with heat-receiving sheets 2. The board is clamped integrally by means of screws 9 via a heat-conducting sheet 3 composed of a heat-conducting and flexible material such as a silicone rubber or the like between the individual heat-generating electronic components and the heat-receiving sheet 2. In order to prevent the drying-out phenomenon of the heat pipe 1, the heat-generating electronic components on the wiring board 4 are arranged in such a way that a highly heat-generating LSI chip package 5 is situated near the radiating fin in the heat- collecting part of the heat pipe 1 and that a low heat-generating LSI chip package 6 is situated at a distance.

摘要： PURPOSE:To reduce the viscosity of a slurry and prevent viscosity increase with time of the slurry in storing, by adding an anionic salt or complexing agent to a coal water slurry in a high concentration when the cation concentration therein exceeds a given value. CONSTITUTION:The cation concentration of a coal water slurry in a high concentration (about >=70wt% coal concentration) is constantly or intermittently measured. When the measured value exceeds a given value, an alkali metal salt of an anion linked to a polyvalent metal ion or complexing agent capable of forming a complex compound linked to the polyvalent metal ion is added.
