摘要： PURPOSE:To reduce the thermal impact upon switching by providing a mixed oil operation stage when switching between standard oil for starting/stopping and inexpensive load operating oil. CONSTITUTION:When starting/stopping a gas turbine, standard oil is fed from a tank 1 through a carry pump 4, mixing station 6 and a fuel oil heater 7 to a gas turbine 8. When switching to the load operation, a changeover valve at the mixing station 6 is operated to gradually increase/decrease the inexpensive B oil from the tank 2 through the carry pump 5 and when reaching to the gas turbine supply temperature, it is switched completely to B oil. Consequently, thermal impact upon switching can be released.

摘要： PURPOSE:To improve accuracy in surveillance, by so constituting that a combustion state is judged by comparing a distribution wave form of an exhaust-gas temperature measured by a number of temperature detectors more than the number of combustors arranged in a coaxial state with a reference wave form, in an axial flow turbine provided with multicylinder type combustor. CONSTITUTION:A plurality of exhaust-gas temperature detectors 22 are provided at regular intervals on a concentric circle with the central axis of a gas turbine and each of temperature detecting signals T1-T2 is applied to a continuous sampling device 23. These data are displayed 29 through a measured temperature's wave data storing and transferring device 24 and are applied to a wave form comparison and deviation computing device 26. A reference wave form calculated by a reference wave form and allowable deviation calculation device 25 based on operation load data 30 is applied to the wave form comparison and deviation computing device 26, which is compared with a measured wave form 24, through which deviation is obtained and applied to a normality and abnormality checkup, control and deciding device 27, a combustion state is judged by comparing it with an allowable deviation and a necessary control signal is applied. In this manner, highly accurate surveillance is obtained.

摘要： PURPOSE:To accurately install and support rotary machines with sufficient strength by supporting the rotary machines by a sleeve buried in advance under an installation foundation when installing and supporting vertical rotary material group arranged in high density. CONSTITUTION:Sleeves 2 are set on an installation floor FL through channels 5 at the positions corresponding to the installing array of rotary machines 1. Then, the sleeves 2 are mutually welded at every sleeve unit with connecting pipes 4. After a concrete pedestal is placed to bury the sleeves 2 in predetermined depth H, the lower portion of the rotary machines 1 are inserted into the respective sleeves 2. After the rotary machines 1 are centered according to the contact with an engaging seat 6, a wedge 7 is inserted by hammering from above into the gap between the rotary machine 1 and the sleeve 2, the flange 8 is welded to the upper end of the sleeve 2 to thus complete the installation of the rotary machine.

摘要： PURPOSE: To aim at improvements in an operation environment, by blowing off cold air in a direction toward a smokestack from air outlets at both side walls of a building, through plural air outlets, while inhaling hot air back ventilation from a suction port neaby the floor surface.
CONSTITUTION: An air conditioner 3 is installed outdoors, then cooling air is led into an air outlet 8 by way of a feed duct 4 and released inside a room. The air warmed up inside the room is taken into the air conditioner 3 and turns to feed air again after being mixed with the outside air. According to this method, air conditioning for a workspace of about 1W2m on the floor of a gas turbine room can be performed, and in combination with a natural draft effect in and around a smokestack, such exhaust 11 as in a fairly higher temperature than that of the outside air taken in is discharged out of a roof fan 6, thereby conducing to a reduction in air cooling load.
