    摘要： The invention is concerned with a method for combined production of nanomaterials and heat. The method comprises feeding at least one precursor material and a fuel into a combustion unit for the generation of heat and nanoparticles, whereby the precursor material is combusted to be decomposed and oxidized in a sufficient temperature. The heat generated in the combustion of the fuel and the precursor material is recovered by using at least one heat exchanger. The combusted fuel is cooled down and the nanoparticles generated in the form of oxides in the combustion are collected. The system of the invention for combined production of nanomaterials and heat comprises a combustion unit, means for feeding at least one precursor material, fuel and oxidizer into the combustion unit for combustion, a heat exchanger for recovering heat from the combustion unit, and for cooling the combusted fuel, and means for collecting nanomaterials in the form of oxides from the combustion of the precursor material(s).

    摘要： An improved heat engine that includes an organic refrigerant exhibiting a boiling point below −35° C.; a heat source having a temperature of less than 82° C.; a heat sink; a sealed, closed-loop path for the organic refrigerant, the sealed, closed-loop path having both a high-pressure zone that absorbs heat from the heat source, and a low-pressure zone that transfers heat to the heat sink; a positive-displacement decompressor providing a pressure gradient through which the organic refrigerant in the gaseous phase flows continuously from the high-pressure zone to the low-pressure zone, the positive-displacement decompressor extracting mechanical energy due to the pressure gradient; and a positive-displacement hydraulic pump, which provides continuous flow of the organic refrigerant in the liquid phase from the low-pressure zone to the high-pressure zone, the hydraulic pump and the positive-displacement decompressor maintaining a pressure differential between the two zones of between about 20 to 42 bar.

    摘要： Apparatus utilizing steam from first, second and third extraction points of a steam turbine in a nuclear power plant steam system as heating steam in at least two feedwater heater units for maintaining the final feedwater temperature above a predetermined temperature value is disclosed. More specifically, when the plant loading is determined above a predetermined first level, the apparatus provides heating steam from the first extraction point to a final feedwater heater unit in the feedwater return path of the steam system and also provides heating steam, which is at a lower pressure than that from the first extraction point, from the second extraction point to another feedwater heater unit which preheats the feedwater prior to entering the final feedwater heater unit. At times, when the plant loading falls below the first level, heating steam, which is at a higher pressure than that of the first extraction point, is provided to the final feedwater unit from the third extraction point and a portion of the steam from the first extraction point is redirected as heating steam for the another feedwater heater unit. Moreover, at times, when the plant loading falls below a second predetermined level, which is lower than the first level, the heating steam from the third extraction point provided to the final feedwater heater unit is increased in pressure preferably by an ejector or jet pump device utilizing motive steam from a high pressure source, and in addition, a portion of the steam from the third extraction point is redirected to the another feedwater heater unit.
