【 摘 要 】

A short characteristic of the heat power industry of the Russian Federation is analysed. Special attention is paid to the technological condition of the central thermal electric main lines and boiler equipment, thermal networks and heat consumption systems. Moreover, it is specified that the important heat supply equipment systems are shell and tube heat exchangers. The emphasis is that the use of shell and tube heat exchanger devices is based on reliable technical solution, financial viability, and convenience in its operation and repair. Based on the analysis of local and foreign scientists' research, the classification of approaches of heat exchange intensification in shell and tube heat exchanger devices is propounded. The article presents the results of thermal and hydraulic tests of an intensive shell-and-tube heat exchanger with increased turbulization of the heated fluid. When carrying out tests, modern high-precision measuring devices are used. A test objective comparison of hydrodynamics (losses of pressure) and heat technical characteristics (heat transfer coefficient) of two heat exchangers has been conducted. These are serial (state standard No. 27590.) and intensive (RU 185391 patent) exchangers.
