Analysis of the Thermal Stress Concentration Coefficients in Tee Joints
Thermal Engineering - Tập 69 - Trang 632-635 - 2022
E. R. Plotkin, T. S. Kontorovich
The concentration of thermal stresses is one of the main factors leading to a decrease in thermal strength under cyclic loading conditions. It is characterized by the stress concentration factor Kt, the value of which can be determined by analytical or numerical methods as well as experimentally. In modern regulatory documents, various values of the thermal stress concentration coefficient are ind...... hiện toàn bộ
Startup of air-cooled condensers and dry cooling towers at low temperatures of the cooling air
Thermal Engineering - Tập 63 - Trang 329-335 - 2016
O. O. Milman, A. V. Ptakhin, A. V. Kondratev, B. A. Shifrin, G. G. Yankov
The problems of startup and performance of air-cooled condensers (ACC) and dry cooling towers (DCT) at low cooling air temperatures are considered. Effects of the startup of the ACC at sub-zero temperatures are described. Different options of the ACC heating up are analyzed, and examples of existing technologies are presented (electric heating, heating up with hot air or steam, and internal and ex...... hiện toàn bộ
Choice of optimal working fluid for binary power plants at extremely low temperature brine
Thermal Engineering - Tập 63 Số 12 - Trang 887-895 - 2016
Г. В. Томаров, А. А. Шипков, Е. В. Сорокина

The heat-recovery power unit of a gas-piston mini cogeneration station
Thermal Engineering - - 2010
A. V. Dzhulii, L. B. Direktor, V. M. Zaichenko, A. V. Markov
The specific features of the thermal operating conditions of the internal combustion engine and the design circuits of a mini cogeneration station’s heat-recovery unit are considered. The basic scheme of the heat-recovery unit’s thermal parameters automatic control system is proposed, the use of which makes it possible to maintain the design temperatures of coolants and heating agents (cooling liq...... hiện toàn bộ
Optimal service life of the cooled blades of gas turbines
Thermal Engineering - Tập 53 - Trang 975-978 - 2006
M. E. Kolotnikov, I. L. Osipov, D. V. Petrunin
We propose a method for calculating the optimal service life of the cooled blade of a gas turbine with the use of a special objective function, representing a comparative profit from the operation of one turbine version or another.
Extending the service life of steam turbines using the systems for cooling the thermally stressed parts of high- and intermediate-pressure cylinders
Thermal Engineering - Tập 59 - Trang 199-203 - 2012
L. A. Khomenok, V. V. Bozhko, I. S. Leonova, I. V. Zaitsev, D. V. Prokhorov
The problem of extending the service life of a large fleet of operating steam turbines is considered. A method for reducing the damageability of the most thermally stressed parts of steam turbines with capacities ranging from 100 to 800 MW is demonstrated. Data on putting in use cooling systems and on their effectiveness in solving the problem of extending the service life of such turbines are pre...... hiện toàn bộ
Studies of a direct-contact feedwater heater at a fragment of the secondary coolant circuit of a new-generation reactor plant
