摘要： PURPOSE:To obtain a high reliability and a long service life of a high temperature gas turbine in which the combustion gas temperature is 1,300 deg.C or more by forming the combustor tail cylinder to a double structure of inside and outside panels and piercing a plurality of holes on the outer peripheral surfaces of the both panels so that air compressed by a compressor is sent therethrough to cool the inside panel. CONSTITUTION:A combustor tail cylinder 5 is made of heat-resisting superalloy of thickness of few milimeters and constituted of the double structure of a high pressure air side panel 10 on the outer side and a low pressure combustion gas side panel 9 on the inner side. The both panels 9 and 10 are provided respectively with a plurality of small holes 12 and 13. The outer surface of the panel 9 is secured with a T-shaped rib 11. Air discharged out of the compressor collides with the surface of the panel 9 in a high speed jet stream from the small holes 12, functions as cooling air, and then flows into a high temperature operation gas 101 through small holes 13. If about 5% of air amount discharged from the compressor functions as the cooling air when the combustion gas temperature is 1,300 deg.C, the temperature drops down below 750 deg.C.

摘要： PURPOSE:To provide an arrangement for a waste heat utilizing power plant in use of organic medium, capable of preventing decomposition of the organic medium due to overheating and generation of corrosive substances, by keeping the inner pressure of drum for a waste heat restoring boiler constant and thereby keeping the temperature of saturated vapor of intermediate heating medium constant. CONSTITUTION:In an organic medium utilizing waste-heat power plant, gas 9 serving as the source of waste heat is carried into waste heat restoring boiler 1, and after heating intermediate heating medium of water therein, generates saturated vapor in drum 2. The saturated vapor 10 thus generated is carried into means 3 for generating saturated vapor of organic medium and heats the organic medium into vapor. Thus, organic medium is vaporized and saturated vapor 12 of the same is supplied to turbine 5 and drives the same and hence generator 7. Vapor discharged from turbine 5 is liquefied in condenser 6 and then carried to vapor generator 3. Here, it is prevented that the organic medium is heated exceesively, by keeping the inner pressure of drum 2 of boiler 1 constant and thereby keeping the temperature of saturated vapor constant.

摘要： PURPOSE:To improve heat exchange performance, by restricting the accumulation of vapor bubbles generated in a heating medium. CONSTITUTION:A heat medium inlet port 2 is provided in the bottom of a container 1. A heat medium outlet port 3 is provided in the upper part of the wall of the container. A low-boiling- point medium outlet port 4 is provided in the top of the container. A low-boiling-point medium feed pipe 5 is laid through the lower part of the wall of the container. The front end of the pipe 5 is coupled to a header 6. A plurality of partition walls 8 are provided between the outlet port 3 and the header 6. Fluid passages 9 are defined between the partition walls 8. A heating medium is uniformly introduced into the passages 9 through the inlet port 2 and the header 6 so that head exchange is effected between the heating medium and a low-boiling-point medium. The heating medium is drained through the outlet port 3. The low-boiling-point medium is introduced into the header 6 through the feed pipe 5 and ejected from holes 7 so that the medium is changed into vapor bubbles 10 by the heat exchange with the heating medium. The vapor bubbles move up in the passages 9 while joining other vapor bubbles. The bubbles are then discharged through the outlet port 4. According to this constitution, the bubbles are prevented from being nonuniformly distributed in the heating medium and the heat exchange performance is improved.

摘要： PURPOSE:To accomplish significant reduction of NOx in a lean combustion method with a number of subcombustion chambers arranged by lessening the size thereof. CONSTITUTION:Air 4 from a compressor passes between an outer cylinder 5 and a liner 6 of the combustion apparatus and fed to a subcombustion chamber 2 in the primary air current through an air inflow port 7, and the secondary air current 10 is fed to the main combustion chamber 3 through an air inflow port 9. Then, a diluted air 12 is introduced to the air current through a dilution port 11 while the combustion gas 13 is inducted to a turbine 7 through a transition piece 14. Fuel 16 is evenly delivered to each combustion device 1 with a flow divider 17, where it is distributed to respective fuel nozzles 15 mounted to a plurality of subcombustion chambers 2. An electromagnetic control valve 19 is provided in the fuel supply passage 18 interposed. With such an arrangement, the subcombustion chamber 2 functions to control the generation of NOx to ensure a constant lean combustion while the electromagnetic control valve 19 is opened ro closed so as to maintain a stable state of combustion.

摘要： PURPOSE:To prevent the pyrolysis of vapor of a low-boiling-point medium, by exchanging heat only through rising tubes pipe through which a heated medium containing the low-boiling-point medium dissolved is passed and by abstaining from heating these media in falling tubes. CONSTITUTION:Waste hot gas 1 is supplied into a shell 11 to heat the rising pipes 9D-9A to indirectly exchange heat with the heated medium 4 flowing through the tubes. The medium 4 is introduced into a lower water chamber 7A through an inlet port 5 and flows to the an upper water chamber 8A through the rising tube 9A while the low-boiling-point medium is heated and evaporated. The vapor of the latter medium is discharged through a gas vent 12. The heated medium 4 then flows to another lower water chamber 7B through a falling tube 10A located outside the passage of the waste hot gas. Such steps are repeated. The heated medium having finished heat exchange is discharged through an outlet port 6.

摘要： PURPOSE:To control the operation of a safety power plant, by means of controlling the solubility of a medium in the exchanger at a constant by regulating the flow quantity to the direct type heat exchanger of the power plant. CONSTITUTION:The heat of a fluid 1 of a heat source is conducted to a high temp. heat medium 3 by a heater 2, and is led to a direct type heat exchanger 4 along with a low b.p. medium used by a turbin. a pressure P of the heat exchanger 4 is detected, and a set temp.T is determined by detected value thereof. The temp. of the high temp. heat medium 3 is detected by a detector 16, and is added by means of introducing to a low b.p. medium flow quantity control device 17 along with a signal of the set temp.T. In a case when the result is negative, it shows that the portion of the temp. of the high temp. heat medium is lower, and the temp. is raised by means of reducing th flow quantity of the low b.p. medium by choking a flow quantity control valve 11 for the purpose of raising the temp., and of reducing the evaporated quantity in the inner part of the heat exchange 4. In a case when the heating value is positive, the reversed control said above is effected.

摘要： PURPOSE:To generate gas from a turbine working medium and eliminae its pyrolysis, by using an intermediate heat medium with a high boiling point between a waste heat fluid and the turbine medium and making the turbine medium directly contact with the intermediate medium in a heat transfer pipe. CONSTITUTION:A waste heat fluid 7 flows through a flow passage 17 and transfers its heat to an intermediate heat medium 8 with a high boiling point through a heat transfer pipe 9. A manifold 12 is fitted to the bottom of the heat exchanger 1 to receive the burbine working medium sent from a pump 6 through a pipe 15. A rectifying plate 11 is fitted in the manifold 12 to project several nozzles 10 into the heat transfer pipe 9. The turbine medium is injected through the rectifying plate 11 and the nozzles 10 into the heat transfer pipe 9 and vaporizes by depriving the intermediate medium 8 of heat. Since the turbine gas in contact with the inner wall of the heat transfer pipe, the turbine medium is prevented from pyrolysis.
