We present the results from the development of a cycle of tutorial laboratory works for remote education under the general title “Dynamics of Systems for Controlling Thermal Process” for students specializing in the discipline of automation of technological processes and production facilities worked out on the basis of the Matlab software package and the Simulink environment for development of sim...... hiện toàn bộ
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
Stages through which polyfractional fuel burns in a bed
Thermal Engineering - Tập 56 - Trang 469-472 - 2009
B. Ya. Kamenetskii
The duration of stages for which black coal fractions weighing from 30 g to 1 kg are prepared and fired in stoker furnaces at different forcing ratios is experimentally investigated. Conditions under which carbon loss occurs and increases during the combustion of fuel in a bed are revealed.
Analysis of the effect of hydrophobic properties of surfaces in the flow part of centrifugal pumps on their operational performance
Thermal Engineering - Tập 62 Số 11 - Trang 817-824 - 2015
А. В. Волков, А. Г. Парыгин, Михаил Лукин, А. В. Рыженков, Г. П. Хованов, А. В. Наумов, Jiří Šoukal, František Pochylý, Simona Fialová
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
Regulatory and Methodical Support of the Transition to the BATs in Heat Power Engineering
Thermal Engineering - Tập 65 - Trang 317-323 - 2018
P. V. Roslyakov, O. E. Kondrat’eva, A. M. Borovkova
Federal Law no. 219-FZ of July 21, 2014, “On the Amendments to the Federal Law On Environmental Protection and Certain Legislative Acts” of the Russian Federation established new principles of environmental policy aimed at significantly reducing the negative anthropogenic impact on the environment. Currently, active work is under way to harmonize the Russian environmental legislation with regard t...... hiện toàn bộ
The Technology of Integrated Cleaning of Fire-Resistant Oils
Thermal Engineering - Tập 68 - Trang 770-776 - 2021
V. V. Martynov, N. V. Arzhinovskaya, N. M. Pervushina, V. A. Petrukhin, A. B. Ponomarev, S. K. Moiseev
Fire-resistant turbine oils on the basis of triaryl phosphate are subjected to hydrolysis with the formation of acids and phenols during operation at power stations in control and lubrication systems of power units. This increases acid number (AN) and leads to the formation of gum deposits on equipment. The process of decreasing AN in waste Reolube OMTI fire-resistant liquids with AN above 1.5 mg ...... hiện toàn bộ
The Selection of Energy Storage for a Micro–Gas-Turbine Plant Operating Autonomously in the Conditions of the North
Thermal Engineering - Tập 70 - Trang 1051-1061 - 2023
A. B. Tarasenko, O. S. Popel, S. V. Monin
On the example of a micro–gas-turbine plant (MGTU) of the C30 Capstone type, an analysis of various options for the use of modern electric energy storage devices as part of a buffer battery was carried out and compared. Gas microturbines with a unit capacity of several tens to hundreds of kilowatts appeared on the market in the 1970s and have become increasingly widely used in autonomous and distr...... hiện toàn bộ

Purification of the heat-carrying agent of geothermal electric power plants by the membrane method
Thermal Engineering - Tập 55 - Trang 602-607 - 2008
V. V. Potapov, V. A. Gorbach, V. N. Kashpura, G. M. Min, I. A. Kashutina, A. O. Sadovnikova
A technological scheme of purification of the liquid phase of the heat-carrying agent of a geothermal power plant (GeoPP) from colloidal silica is presented. It is developed taking into account the physical and chemical characteristics of the water heat-carrying agent and the kinetics of forming and the sizes of the colloidal silica particles. It includes some devices for baromembrane filtering. E...... hiện toàn bộ
