摘要： The heat transfer performance of a gas cooler provided with a fin tube type heat exchanger is improved. This is a gas cooler 10 which is provided with a heat exchanger 6, cools a gas to be cooled, which is introduced from the outside, by performing heat exchange between the gas to be cooled and the heat exchanger 6, and discharge the cooled gas to the outside. The heat exchanger 6 includes: a plurality of heat transfer fins 8 which are placed side by side via a prescribed gap therebetween, the gas to be cooled flowing through the gap; and heat transfer tubes 7 which pierce through the plurality of heat transfer fins 8 and are provided in a plurality of rows along the direction in which the gas to be cooled flows. The outside diameter d o of the heat transfer tubes 7 is 20 to 30 mm.

摘要： PROBLEM TO BE SOLVED: To provide a compressor preventing leakage (inflow) of fluid having the same component as the compressed fluid into a bearing part, and suppressing increase in manufacturing cost while implementing shaft-seal of compressed fluid (product gas).
SOLUTION: The compressor comprises: a casing 11; a shaft body 14 rotatably supported in the casing 11 through bearing parts 12, 13; an impeller attached to the shaft body 14 and rotated to compress the compressed fluid G; shaft seal parts 17, 18 each of which is fixed in the casing 11 and is projected toward a shaft body 14 side, and to which the fluid (first fluid) 16 having the same component as the compressed fluid is supplied to shaft-seal the compressed fluid G; a second supply passage 20 supplying inert gas 19 into the casing 11; pumps 22, 23 connected to the casing 11 to discharge the inert gas in the casing 11. Therefore, flowing of the first fluid 16 into the bearing parts 12, 13 is prevented.

摘要： PROBLEM TO BE SOLVED: To avoid the surging of a compressor by arranging a rotational speed limiter to output a second opening signal by which the opening of a regulating valve is controlled to be enlarged when a rotational speed is high and contracted when the rotational speed is low according to a signal from a rotational speed detector when a changing speed exceeds a threshold value in a rate-of-change limiter. SOLUTION: In case that an output signal from a comparator 24, received in a rate-of-change limiter 25, is a fully opening command signal, an output signal corresponding to the rotational speed of a compressor 1 is calculated by a rotational speed limiter 25a, and this output signal is outputted as a second opening signal for controlling the opening of a regulating valve 6, to a maximum value selector 26. In the maximum value selector 26, any larger value out of a first opening signal from a controller 13 and the second opening signal from the rate-of-change limiter 25, is selected and outputted to the regulating valve 6, so that a valve opening is operated. Hereby, influence exerted on the wake side of the compressor 1 is diminished, and the compressor can be returned immediately to a normal operation by loose flow control from a normal operational condition.
