Shell and tube heat exchangers – efficient and economical thermal solutions

The efficiency of use of thermal energy in conditions of market economy it is possible to classify the main factors that have a direct impact on the definition of the strategy of technological re-equipment and modernization of any enterprise. Reliability, efficiency, availability and warranty service today are the basic pillars of economic success and prosperity of all participants in economic relations.

When purchasing new equipment every organization is guided first of all above criteria. High quality shell and tube heat exchangers are so efficient and economical equipment. Today, the relevance of these devices for the enterprises of any profile and orientation are not even exposed to doubt. At the present time, shell and tube heat exchangers are most widely used in petrochemical, chemical and food industry, housing and utilities sector and energy industry.

Clarity, brightness the latest techno-economic decisions with a lot of advantages compared to outdated types of equipment, have recently attracted more and more enterprises of different sectors of the economy. Because shell and tube heat exchangers can significantly reduce the thermal consumption, which positively affects the cost of production and, therefore, its ultimate price. And it is extremely important in today's economic realities with the demands of stiff competition.

Shell and tube heat exchangers represent the apparatus, where the heat exchange process between different operating environments (regardless of their technological specifications and energy use). Typically, these devices perform the functions of heaters, evaporators, condensers, pasteurizers, deaerators, economizers, etc.

Shell and tube heat exchangers can have extremely diverse technological purpose and can be used in the production of different profile. The range of application is today is extraordinary. Shell and tube heat exchanger, the main structural elements of which are bundles of pipes with grilles, casing, Spigots and covers can be used as the unit in which the transfer of thermal energy is the main technological process or as a reactor in which heat transfer is purely auxiliary character.

The Principle of operation of shell and tube heat exchangers based on the process of heat transfer from the environment moving at high speed inside the pipes of small diameter, the medium circulating in the casing. With the purpose of intensification of process of heat exchange these units are often equipped with special baffles in the pipe and annular spaces.

Shell and tube heat exchangers can be vertical, horizontal or inclined spatial orientation (depending on the process requirements and in accordance with the ease of installation). These units are full-fledged alternative to plate heat exchangers, compared with which though have lower efficiency of energy transfer, but are relatively simple design and low cost, what could be the decisive argument for the selection of such equipment.
