摘要： In a heat pump system including a water purifier (1) and an evaporator (2) for evaporating feed-water (10) to produce steam (12), water (11) used for spray cooling is effectively used and productivity of purified water used for the spray cooling is increased.
Discharged water (21) from the water purifier (1) is supplied to the evaporator (2) when water used for spray cooling is produced by use of the water purifier (1). Otherwise, drain (22) of the evaporator (2) having higher temperature is supplied to the water purifier (1) by using such a fact that in a reverse osmosis membrane type water purifier (1), the higher the temperature of feed-water (10) is, the higher the purified water productivity becomes.

摘要： Disclosed is a highly efficient, less expensive turbine nozzle blade that reduces the number of blades in an axial-flow turbine, while at the same time, reducing secondary-flow loss. In the turbine nozzle blade, when a differential pressure between a pressure side and a suction side of each blade, at one same axial chord position of the blade, is defined as a load of the blade, and a ratio between axial chord length "Cx" of the blade and an axial distance "xp" from a leading edge 8 of the blade at a maximum load position 32 which maximizes the blade load is defined as a maximum load relative position, the axial chord length "Cx" of the blade is greater at a hub and tip thereof than at an intermediate vertical portion thereof, and simultaneously a maximum load relative position at the hub and tip of the blade is set to be nearer to a trailing edge thereof than a maximum load relative position of the intermediate vertical portion of the blade.

摘要： A method of controlling an operation of a 2-shaft gas turbine comprises, when an operation of a 2-shaft gas turbine is changed to reduce a load from a predetermined load, a first step of reducing a rotating speed of a compressor (1) and a second step of reducing a working airflow in the compressor (1). With the method, a reduction in compressor (1) efficiency during partial load operation of the gas turbine can be suppressed, and a surge margin of the compressor can be ensured.
