The value of increasing the efficiency of tubular heat exchangers by using turbulators
Introduction Heat transfer enhancement in all types of heat exchanger systems is of great significance for the cooling and heating industry. In addition to saving energy, it also leads to a reduction in size and weight of equipment. In the last decade energy efficiency has become an increasingly important theme among policy makers as it can enable economic growth, reduce emissions and improve ...

The benefits of heat regeneration in heat exchanger systems
Heat exchangers which employ heat recovery or regeneration should not be confused with ‘regenerative heat exchangers,’ which are a specific type of heat exchanger. What we mean by heat regeneration at HRS is the recovery of as much surplus heat (or cooling capacity) as possible after the primary function of the heat exchanger has been performed. This can then be reused to either ...

Why are fluoropolymers are used for the construction of industrial heat exchangers?
Right now, we are in the middle of summer, so heat is probably on your mind. Heat exchangers exist in all sorts of applications. Your heating system might use a metal heat exchanger to transfer heat. This could mean it’s made of carbon and stainless steel, copper, aluminum, or another metal. Low temperature plastic may also be used in the construction of the heat exchanger in a heating ...

Behaviour of a natural circulation facility with a two-phase flow and in the presence of noncondensable gases for research and development of an emergency cooling system of advanced nuclear reactors
This work presents the results of tests and simulations of the behaviour of an experimental facility called Natural Circulation Loop (NCL) when different volumes of noncondensables are trapped in the top header of the heat exchanger and with the system operating in a two-phase flow. The main objective of this project is to study the behaviour of a passive emergency cooling system of advanced ...

Exergy analysis and performance evaluation of CNG to LNG converting process
A process for converting Compressed Natural Gas (CNG) to Liquefied Natural Gas (LNG) is modelled thermodynamically and effects of design and operating parameters on exergy destruction and performance of the process are studied. Results show that CNG pressure, pressure after Joule?Thomson valve, and temperature of CNG after heat exchanger of refrigerating system have significant effects on optimum ...

Preventing product contamination with double tube plate heat exchangers
Ensuring product safety is the number one priority for any producer of pharmaceutical products, and a key aspect of this is avoiding contamination during production. Design and construction plays a key role in achieving this, and the heat exchangers used for processes such as pasteurisation and sterilisation are no exception. There are three main elements to preventing contamination occurring in ...

World geothermal power generation nearing eruption
With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth’s heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total ...

The Major Components of Heat Exchangers
Heat exchangers are not only one of the most common pieces of equipment found on industrial sites, they are also one of the most important. Despite the name, heat exchangers are used for both heating and cooling and are actually used more often for cooling, especially on industrial sites such as refineries or processing plants. These pieces of equipment are not “one size fits all.” In ...

The Entropy Generation Minimisation based on the Revised Entropy Generation Number
In the present work, an improved Entropy Generation Minimisation (EGM) approach aiming at minimising the revised entropy generation number which is the non-dimensionalised entropy by the ratio of heat flow to the input temperature of the cold fluid is developed for a plate-fin heat exchanger design with multiple design variables with the help of genetic algorithm. It is found that the approach ...

The Role of Heat Exchangers in Apple Juice Processing
While heat treatment is important in ensuring the safety of apple juice through pasteurisation or sterilisation, for some products heat plays an important role in the production process itself. The physical and chemical properties must be considered when they are juiced and processed. Sugar content is typically around 11%, while dry matters vary between 13 and 20 % depending on variety and ...

On-Vehicle Exhaust Gas Cooling in a Diesel
ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is necessary. A finned-tube heat exchanger is included in the system to cool the exhaust gas to ...
