Title: Gas turbine combined plant
Inventor: ISHIGURO TATSUO
IPC: F01K23/10
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To improve an efficiency by suppressing condensed latent heat of steam turbine outlet steam, in a gas turbine combined plant. SOLUTION: Compressed air in a compressor 1 and fuel are burnt by a combustor 2, gas is expanded in a gas turbine 3, to drive a power generator 8. Exhaust gas 104 enters in an exhaust gas boiler 4, steam 108 is heated by a gas 105 so as to generate an exhaust gas 106. Outlet steam 109 from the exhaust gas boiler 4 is expanded in a steam turbine 5 to generate an outlet steam 110. Although the outlet steam 110 is cooled in a steam cooler 10 to generate outlet steam 112 of a low temperature, the steam does not condense but becomes the outlet steam 112 compressed by the steam compressor 11 to generate delivery steam 113, and it is supplied to the exhaust gas boiler 4. Since the steam will not condense in the steam cooler 10, the loss of steam condensed latent heat becomes small in a low level so as to improve an efficiency of the plant.

Filed: 1989-12-20
Abstract: PURPOSE:To improve the appearance and brightness of reflectivity by making one side of surfaces into laser dull finished surface and making the other side into rough dull finished surface in an aluminum alloy plate for press forming. CONSTITUTION:In the drawing process of the outside plate of automobile, a material 4 is inserted in the state that a punch 1 is lowered. Next, the material 4 is held by lowering a blank holder 3. Successively, the punch 1 is lifted and the material 4 is given plastic deformation and formed into an initial shape. In the case that the material has the laser dull finished surface, projecting defects are made due to handling flaws which are generated by bringing the material 4 into contact with the punch 1 when the material is inserted in a press and sticking of dust. On the other hand, in the case of rough dull finished surface, since dust and projecting flaws are absorbed by its own ruggedness, they are not appeared as the projecting defects of the outer surface. From that result, the surface of one side is made into the laser dull finished surface of excellent brightness of reflectivity and the rear side which is brought into contact with the punch 1 is made into a dull finished surface which as low sensibility to flaws and dust.
