摘要： PROBLEM TO BE SOLVED: To provide a technique suitable for energy recovery from normal-pressure/high-temperature gas.
SOLUTION: In this turbine system, a combustor 12 is disposed at a front stage of a turbine 16 of turbomachinery whose turbine 16 is connected with compressors 20, 24 by a shaft. Working fluid passes through the turbine 16 and compressors 20, 24 in this order to generate shaft output. Further, this turbine system comprises: a regenerating heat exchanger 14 for cooling high temperature working gas from the turbine 16 by mixing the working gas with exhaust gas to heat the mixture, and heat-exchanging the mixture with air humidified by hot water; coolers 22, 26 for cooling the working gas by heat-exchanging the working gas with water at an inlet of the compressor and between the compressors 20, 24; and a humidifier 30 for mixing air with part of exhaust gas from the compressor 24 to heat the mixture, and humidifying the mixture by using hot water generated by the heat exchange with working gas in the coolers 22, 26. In this turbine system, mixed gas from the humidifier 30 is introduced to the regenerating heat exchanger 14 to be preheated by heat exchange with the high temperature working gas at an outlet of the turbine 16, and the preheated high-temperature/humid mixed gas is introduced in the combustor 12.

摘要： PROBLEM TO BE SOLVED: To previously detect indications of a malfunction in a rotating machine by shaft vibrations, and to suppress the amount of data on the shaft vibrations required for diagnosis to a minimum in consideration of remote diagnosis.
SOLUTION: This condition diagnosing apparatus comprises a data collector 1 for collecting operation data comprised of data on the number of revolutions and vibrations of a shaft system of the rotating machine, a data communication part 2 for transmitting the collected data to a data processor, the data processor 3 for performing signal processing for determining indications of damage in a bearing from the data transmitted from the data collector; and a display unit 4 for displaying the result of the processing. By monitoring amplitude values of the shaft vibrations of the rotating machine, the occurrence of a malfunction is previously predicted. Even from very small changes in the shaft vibrations, changes in conditions are detected to diagnose anomalies at an early stage. From a very small amount of vibration data, changes in conditions are detected.

摘要： PURPOSE:To prevent the slag flowdown port of a cyclone combustion furnace from clogging by inserting an optical sensor to the port at its downstream side, and detecting the quantity of light at the lower part of the port. CONSTITUTION:An optical sensor 6 is so mounted in a passage communicating a slag flowdown port 3 with a slag tank 5 as to be directed in a direction capable of measuring the quantity of light at the periphery of the lower part of the port 3 from the atmospheric side. The cooling and solidification of slag in the port 3 are advanced while a combustion furnace 1 is operated for a long period of time, and the quantity of the light measured by the sensor 6 is abruptly reduced upon approaching of the port 3 to a completely closed state. Accordingly, when the quantity of the light measured by the sensor 6 is reduced lower than a predetermined numerical value, a slag lance is immediately inserted into the port 3 to peel the adhering slag of soft state from the port 3 and to drop it in the tank 5. Accordingly, it can prevent the port from clogging.

摘要： PURPOSE:To increase the temperature of pulverized coal combustion air, to shorten the ignition time of pulverized coal and to reduce the generation of nitrogen oxides from inflammable combustion gas by extracting high-temperature combustion gas out of a boiler main body and providing a means for mixing the extracted combustion gas with the pulverized coal combustion air in a cyclone coal combustion furnace. CONSTITUTION:High-temperature combustion gas whose combustion has finished within the combustion chamber of a boiler main body 2 is partly sucked in by an ejector 14 disposed on a pulverized coal combustion air duct at the inlet part of a cyclone coal combustion furnace 1, and the sucked combustion gas is mixed with pulverized coal combustion air to be directed into the cyclone coal combustion furnace 1 as an air-gas mixture at a high temperature. The temperature of the combustion gas within the combustion chamber of the boiler main body 2 is always higher than an air temperature at the outlet port of an air gas preheater 4, and hence it becomes possible that the temperature of the pulverized coal combustion air directed into the cyclone coal combustion furnace 1 is made to be always higher than the air temperature at the outlet port of the gas preheater 4 by means of the suction of the high- temperature combustion gas to be mixed with the combustion air.
