摘要： PROBLEM TO BE SOLVED: To provide a turbine plant and a starting method therefor, the turbine plant having an appropriate axial arrangement of devices such as a gas discharge compressor and the like, a good operability, and a high efficiency and low in construction cost. SOLUTION: The turbine plant is organized as follows. Fuel is burned in a burner 1 with oxygen used as an oxidizing agent. High-temperature gas thereby generated is used to drive high-temperature turbines 2a, 2b. Discharge gas from the high- temperature turbines 2a, 2b are thermally recovered by a heat exchanger 3. Discharge gas from the heat exchanger 3 is compressed by compressors 4a, 4b and then delivered to the burner 1 for recirculation. Meanwhile, the discharge gas from the heat exchanger 3 is used to drive a low-pressure turbine 5. Steam contained in the discharge gas discharged from the low-pressure turbine 5 is condensed by a condenser 6. Condensate is then introduced to the heat exchanger 3. The condensate is then heated and vaporized by using the discharge gas from the high-temperature turbine 2b as a heat source. Resultant steam is used to drive a high-pressure turbine 7. The discharge gas left uncondensed by the condenser 6 is compressed by a gas discharge compressor 8 before being discharged. The turbine plant is characterized in that the gas discharge compressor 8 is disposed coaxially with the low-pressure turbine 5. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To suppress the pulsation and stagnation of saturation water and to achieve safe operation by setting the rising side connection position of an evaporation pipe at a higher position than the downcast pipe side connection position of the evaporation pipe. SOLUTION: A heat gas G flowing in a perpendicular direction in a gas passage part 12 exchanges heat with saturation water (supply water) flowing in evaporation pipes 5a and 5h, and the saturation water becomes a gas/liquid two-phase flow of steam and saturation water and flows to a rising pipe 8 via outlet header pipes 6 and 6a and flows into a steam drum 1. In the steam drum 1, steam and saturation water are separated by a gas/water separator 13, the separated steam is supplied to a steam turbine or the like via a steam outlet 14, and the saturation water falls down a downeast pipe 2 and is allowed to flow back to the evaporation pipes 5a and 5h. In this case, the evaporation pipe 5a that is arranged at the most upstream and downstream sides is formed at a straight pipe that is inclined toward the upper right for promoting the circulation force of the saturation water, and a water hammer or the like are prevented, thus shortening a starting operation.
