摘要： PURPOSE:To attain a high thermal efficiency of a power plant in stable manner independently of the change in the quantity of input heat, by detecting the level of condensate in a condenser for condensing vapor after use for driving turbine, and controlling the amount of condensate to be supplied to a direct heat exchanger on the basis of the detected level of condensate in the condenser. CONSTITUTION:In the low-boiling medium utilizing power plant shown in the drawing, high-temperature fluid 3 heated in a heater (not shown) is carried into direct heat exchanger 4, in which it exchanges heat with low-temperature fluid 6 of low-boiling medium and vaporizes the same. By driving turbine 7 by the vapor of low-boiling medium, power is generated from generator 8. Vapor discharged from turbine 7 is condensed in codenser 9 and then carried back to heat exchanger 4 via pump 11 and flow control valve 12. Here, a detector 14 for detecting the level of condensate is provided in condenser 9. Output of the detectot 14 is compared with a set level of level setter 21 in means 22 for controlling the flow rate of low-temperature fluid, and flow control valve 12 is controlled on the basis of the difference of this comparison.

摘要： PURPOSE:To improve heat exchangeability by providing a partitioning plate in the direction of dividing flow in a heat exchanger so as to prevent joining of low boiling point media's steaming foams. CONSTITUTION:Heating side's heating media introduced from a heating media intake passes through a low boiling point media branch pipe 2, undergoes heat exchange in a space formed by a partitioning plate 4 and becomes discharged from a hot media outlet. Heated side's low boiling point media is jetted out from jetting branch pipe's jet hole 3 toward a space formed by the partitioning plate. Thus jetted out low boiling point media exchanges heat with the heating media and becomes turned into steaming foams 5 after undergoing phasic change from a fluid body to a gaseous body. The steaming foams 5 go up while joining with each other in the space, leave the liquid surface and become discharged. By providing such a partitioning plate 4, joining of the steaming foams 5 become limited in joining area and size, and the foams become uniformly distributed in a heat exchanger, and therefore, occurrences of whirlpool and partial flow are prevented and heat exchangability is improved.

摘要： PURPOSE:To decrease NOx, by providing in the top of combustor a fuel evaporation pre-mixing chamber for evaporating atomized fuel with heated air in front of a combustion chamber to produce pre-mixed gas with air. CONSTITUTION:The fuel evaporation pre-mixing chamber 14 has one end opened outside the top 9a of a combustion chamber and another end closed and cuopled to the wall of the combustion chamber. Fuel nozzles 11a, 11b are attached to the open end to supply fuel to pre-mix the evaporated fuel 13 with air 4c. The point of coupling of the closed end of the chamber 14 with the combustion chamber 9 is located at a distance of 0.5 to 1.0 time of the diameter d of the combustion chamber from the nozzle 11b installed in the center of the closed end of the combustion chamber. The pre-mixed gas is introduced into the combustion chamber 9 through a feed hole 18 to perform diluted low-temperature combustion. Thereby, a no-flame top combustion chamber 9a is defined in the pre-mixing chamber 14. As a result, an evaporation type combustor for stable combustion in a wide range of burning conditions is obtained, and NOx is greatly decreased.
