Could anyone try to correct my mistakes? The first chapter contains some basic information’s about widely understood known heat exchangers (or 'widely understood heat exchanger principles'). Has been described It describes the basic division, types of apparatus and the first solutions used to increase the heat exchange surface. The second chapter has been dedicated to classic laminated heat exchangers it means (i.e. shell and tube exchangers) with heating mantles, laminated. Has been presented Various/(or 'several') types are presented, like such us ''tube in tube'', coil, and spiral. [I only corrected up to here, hope someone else can correct the rest for you!] The specificity of these types of apparatus contain the theoretical description, schematics and possibilities of using. Next, has been described the construction of the typical finned tube heat exchanger based on the information’s which has been made available by the company GEA Sp. z o.o; The paper presents the division of this type of instrument in terms of construction. Has been widely described types of finned tubes using recently for the construction of modern heat exchangers, for example used by GEA Sp. z.o.o. elliptical finned tubes . Whereas the company Famet S.A. used round finned tubes together with methods of impose and criteria for the selection of the method. The analysis showed that the finned tubes with the elliptical cross section in many ways are a much better option than the traditional round finned tubes. There’s also presented the methodology of calculation of finned heat exchangers, which contains a description of basic calculation. In the research part specified the impact of changes in scale, thickness and number of ribs on the stream of heat given off by the tested heat. The computations were performed to comparison tube equipped with a certain number of ribs. The case of the pipe not equipped and additional heat exchange surface relative to the dissipation of the total heat flux Qc. Experimental studies have demonstrated legitimacy the application of the heat exchange surface to develop on the side where the heat transfer coefficient α is very small.
