Rationality and efficiency of using heat energy in a market economy can be classified as the main factors that directly influence the definition of the strategy of technological re-equipment and technical re-equipment of any enterprise. Reliability, economy, accessibility of warranty and service maintenance are today the basic elements on which the economic success and prosperity of all participants in economic relations is based.
When purchasing new types of equipment, any organization is guided primarily by the above criteria. High-quality shell-and-tube heat exchangers are such efficient and economical equipment. Today, the relevance of these devices for businesses of any profile and focus is not even questioned. At present, shell-and-tube heat exchangers have been widely used in the petrochemical, chemical and food industries, in the housing and communal services and in the energy sector.
The visibility, the brightness of such new technical and economic solutions, which have many advantages in comparison with obsolete types of equipment, are attracting more and more enterprises of various branches of the economy. After the shell-and-tube heat exchangers can significantly reduce the consumption of heat, which positively affects the cost of production and, therefore, at its final price. And this is extremely important in modern economic realities with their conditions of fierce competition.
Shell-and-tube heat exchangers are devices where the heat exchange process takes place between different working environments (regardless of their technological specification and energy purpose). As a rule, such devices perform the functions of heaters, evaporators, condensers, pasteurizers, deaerators, economizers, etc.
Shell-and-tube heat exchangers can have an extremely diverse technological purpose and are used in the production of a wide variety of profiles. The spectrum of their application today is unusually wide. Heat exchanger shell and tube, the main structural elements of which are bundles of pipes with grids, hulls, nipples and covers, can be used as an aggregate in which the transfer of heat energy is the main technological process, or as a reactor in which heat exchange is purely auxiliary.
The principle of operation of shell-and-tube heat exchangers is based on the process of heat transfer from a medium moving at high speed inside small diameter pipes to a medium circulating in a casing. In order to increase the intensification of the heat transfer process, such aggregates are often equipped with special partitions in the pipe and intertubular spaces.
Shell-and-tube heat exchangers can have a vertical, horizontal or oblique spatial orientation (depending on the requirements of the process and in accordance with the convenience of installation). Such units are a full-fledged alternative to plate heat exchangers, in comparison with which, although they have a lower efficiency of energy transfer, they have relatively simple design and low cost, which can be a decisive argument when choosing such equipment.
