Analysis of the Thermal Stress Concentration Coefficients in Tee JointsThermal 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 airThermal 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

The heat-recovery power unit of a gas-piston mini cogeneration stationThermal 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 turbinesThermal 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.
