Determination of Minimum Flow Rate of Low Pressure Cylinder of Steam Turbine under Deep Peak Load Regulation Conditions [PDF]
Journal of Mechanical Engineering, 2020 : The inlet flow rate of steam turbine obviously is reduced when the thermal power unit is involved in peak load operation, even under the small volume flow condition, which has the great influence on the safety of steam turbine.

Effective Bulk Modulus in Low-Pressure Pump-Controlled Hydraulic Cylinders [PDF]
ActuatorsIn this paper, the effective bulk modulus of pump-controlled hydraulic cylinders is studied in the context of linear time-invariant modeling and control. Using an experimental test-rig, the minimum expected value of the effective bulk modulus is identified, and its impact on stability and achievable performance under feedback control is analyzed.

Increasing the Operation Efficiency of Low Pressure Cylinders of Cogeneration Turbines
NTU "KhPI" Bulletin: Power and heat engineering processes and equipment, 2017 An increase in the operation efficiency of cogeneration turbines used by big heat and power plants is conditioned by the need of a maximum use of the fuel heat, mainly that of natural gas. The generation of two types of energy, in particular electric and thermal by cogeneration turbines for outside consumers is closely related to turbine operation ...

Transactions of the Korean Society for Noise and Vibration Engineering, 2007 A 7K60MC-S low speed diesel engine in a power plant has frequently experienced high vibration since the unit completed construction works. Up to date, no fundamental vibration solutions were reached. Hence, several vibration tests and analyses were conducted to identify the root cause of this high vibration and to suggest the optimal countermeasures ...

Development of an optical time-resolved measurement system under high-pressure and low-temperature with a piston-cylinder pressure cell [PDF]
Review of Scientific Instruments, 2016 To perform the femtosecond pump-probe spectroscopy under high pressure and low temperature, we constructed a measurement system with a piston cylinder type pressure cell installing an optical fiber bundle. The applied pressure was achieved to 6 kbar and the cell was cooled down to 15 K.
