摘要： PURPOSE:To improve the durability of a catalyst supporting member by a method wherein the catalytic layer is supported in the manner forming a circular space by a corrugated metal elastic member on the internal peripheral surface of a burning liner and part of combustion air is blasted out through the liner to cool the metal elastic member. CONSTITUTION:Catalyst 4 is supported forming a circular space 26 by a corrugated metal elastic member 21 inside a burning liner 2. In this structure, part 106 of the burning air 101 going toward the burning area in the space portion 13 flows from small holes 28 of the burning liner 2 into corrugated spaces 24 and enters neighboring corrugated space 25 through small holes 29 of the metal elastic member 21. In this manner the air passes the corrugated spaces 24, 25 sequentially and flows out to trapping the side. In the meantime the metal elastic member 21 is cooled. In this structure the durability of the metal elastic member 21 is raised and reliability of the catalyst supporting is improved.

摘要： PURPOSE:To improve the starting stop load variation characteristic and the partial load characteristic of a power plant by driving an air compressor by a gas turbine using a fuel gas refined from coal and also providing an air storage cavity storing high pressure air. CONSTITUTION:Coal is gasified in a gasification furnace 10, and the gas is desulfurized by a purifying device 16. The purified gas is used as a fuel of a gas turbine 19. An air compressor 35 is driven by the gas turbine 19, and high- pressure air is stored in an air storage cavity 32. When a request for power generation was produced, power generation is performed by the produced fuel gas and stored air. A steam turbine 23 is driven by the steam generated by a fuel gas steam generator 11 and a waste heat recovering boiler 21. In this manner, it is possible to independently handle the load variation of the power plant and the operation of the coal gasification plant, and hence the starting stop load variation characteristic and the partial load characteristic can be improved.

摘要： PURPOSE: To prevent the drop of turbine efficiency by a method wherein a part of the recompressed air of a recompressor of captioned burner, in which liquified natural gas of the like is used as fuel and as well as the reduction of NOX is contrived, is branched off at the downstream of the recompressor to be supplied through a controlling value to pipings, one of which is for diluting and the other for secondary combustion.
CONSTITUTION: A part of the air 100 compressed by means of a compressor 1 is led to the recompressor 2 in order to be recompressed as the recompressed air 103, which is led to a premixing chamber 3 and mixed with the fuel for precombustion 106 to be sent to and burned in the precombustion chamber 11. On the other hand, the remaining part 101 of the compressed air 100 joints the recompressed air 116, which is branched of from the recompressed air 103 discharged from the recompressor 2, on the way to flow in a main combustion chamber 12 as the air for dilution 104 and the combustion air 105 in the main combustion chamber 12. At this time, the flow rates of fuel for precombustion and of air flowing in the premixing chamber 3 are detected by flow detectors 121 and 122 in order to control the opening and closing of the controlling valve 117 through a controlling device 125. Consequently, the drop of the turbine efficiency can be prevented.

摘要： PURPOSE:To achieve a stationery heat-exchange performance and prevent superheating of the org. medium at the cut let of the reheater by regulating preheated extent of an organic medium in the preheater, by controlling the flow rate of hot heat medium. CONSTITUTION:Steam is generated by a turbine driven by the vapour of an org. medium such as ''Flon'' , which is heated by a hot intermediate heat medium 14 introduced into a direct heat exchanger 3 after heating it in an oil heater 2 by a hot waste gas 1. The vapour is led by a pipe 11 to turbine to drive a generator. The organic medium liquefied during the task is fed into a preheater 7 by a pump 9. A flow control valve 17 is disposed adjacent to an exit of an oil pump 8 and a thermometer 15 for liq. organic medium 12 is equipped close to an exit of the preheater 7. The flow control valve 17 is controlled by a thermostat 16 on an output of the thermometer 15, thereby preventing organic medium from being overheated at the exit of the preheater.

摘要： PURPOSE:To raise the circulating force of hot fluid and cold fluid and the heat exchange capacity, by ejecting the hot fluid and the cold fluid in the same direction in a direct heat exchanger. CONSTITUTION:In the direct heat exchanger 1, the hot fluid and the cold fluid are ejected upward in the same direction from hot fluid nozzles 4 and cold fluid nozzles 5. The cold fluid is evaporated by the heat of the hot fluid so that bubbles 6 are made from the evaporated cold fluid. When the bubbles 6 float up, the bubbles have a driving force to move the hot fluid in the same direction. Then, the bubbles 6 are supplied to a heat load through a pipe 31. The temperature-reduced hot fluid is conducted through a pipe 25 to a cooler 8 which is cooled by the cold fluid 3. Thereafter, the hot fluid is introduced into a heater 11 heated by a heating fluid 10. The heated hot fluid is conducted again to the nozzles 4.

摘要： PURPOSE:To raise the thermal efficiency of a turbine of a steam plant having a direct heat exchanger wherein a medium of low boiling point is used as a working medium, by spraying the working medium into steam generated by the heat exchanger to saturate the steam. CONSTITUTION:An intermediate heat medium heated is supplied from an intermediate heat medium inlet port 2. Another heat medium to be the steam is supplied from an inlet port 4 and projected as a jet 10 to the intermediate heat medium. The heat medium exchanges heat with the intermediate heat medium so that the heat medium rises as steam bubbles 11. At the same time, the intermediate heat medium flows in a direction 9, goes over a liquid level control weir 8 and flows out of an intermediate heat medium outlet port 3. The steam passes through the liquid level 13. To keep the steam saturated, a part of the heat medium is supplied from a regulating heat medium inlet port 5 and is atomized and mixed with the steam. The saturated steam is separated from the intermediate heat medium mist by a mist separator 7.
