Heat Exchanger Articles & Analysis

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 ...

Shell and tube heat exchangers are used for the flow of in-line heating and cooling. The innovative design allows the movement of fluids through the tubes and exterior shell delivering changeability. The movement of fluid can be run in a counterflow, cross flow, or parallel mode. The flow of the fluids can not be reversed, so the development of dirty pockets is then eliminated during the ...

There are numerous uses for heat exchangers in breweries, from cooling, pasteurising and fermenting products, through to efficiently dealing with waste streams such as yeast slurry. Compared to other methods of heating, heat exchangers can be much more energy efficient, providing both environmental and economic benefits. One of the first uses of heat exchangers in brewing is for rapidly cooling ...

In this paper, the optimal operating conditions of a hypothetical combined single flash-binary geothermal power plant are investigated and performance analyses are performed based on Aydin-Germencik field in Turkey. The relationship between flashing pressure, turbine inlet pressure of the binary cycle and total heat transfer area of the heat exchanger are determined for maximum power output of ...

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 ...

Micro heat exchangers using smart fins undergo variation of temperature along the passage of fluid flow. This requires analysis of these smart cantilevers under thermal load. In the present research, thermal analysis of bi-metallic smart, surface mounted, piezo patched cantilevers under thermal excitation, has been carried out. Electro-thermo-elastic governing equations and constitutive equations ...

All but the most basic heat exchangers are created to a bespoke brief, designed to take into account the material/s being heated or cooled, the heating or cooling medium, the amount of product being processed, product velocity, risk of fouling and a host of other factors. However, over the years some standard design types have emerged (as well as more specific types) and understanding the ...

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 ...

Stainless steel corrugated plates have several key characteristics, including: 1. Efficient Heat Transfer: The thin, corrugated stainless steel plates used in the design of heat exchangers provide efficient heat transfer with an extremely small footprint, making them ideal for demanding installations where space is at a premium. 2. High Pressure and Temperature Resistance: The brazed plate heat ...

Operators of anaerobic digestion (AD) plants know how important it is to optimise energy use across all stages of the process. That is why many recapture as much heat as possible for reuse elsewhere, including from the hot exhaust gases generated by the combined heat and power (CHP) engines which turn the biogas from the AD plant into useful heat and electricity. Heat exchangers used for exhaust ...

The 500 MWe Prototype Fast Breeder Reactor (PFBR) is under construction at Kalpakkam. It is a liquid metal sodium-cooled pool-type fast reactor with all primary components located inside a sodium pool. Fission heat is transferred to a secondary sodium system in an intermediate heat exchanger, which is in turn transferred to water in a Steam Generator (SG). The PFBR-SG is a vertical shell and ...

Thermo–economic analysis of Heat Pipe Heat Exchanger (HPHE) for waste heat recovery in thermal systems using the P1–P2 and NTU methods is presented. The optimum effectiveness of a HPHE is given as a polynomial equation, whereas the net savings and payback period are given in closed form to enable the HPHE designer to determine the optimised values directly. In addition to this, exergy analysis of ...

The objective of this paper is to create a small power plant, (producing 2 MW annually), which will be using solar energy as a driving fuel. The system is made up of three sub-systems: a set of Solar Collectors (SCS), a Rankine power cycle and a Heat Exchanger Network (HEN). Two cases with variations in the operation of the solar collectors and the heat exchanger network will be examined. The ...

Energy devices and buildings are sustainable if, when they operate, they use sustainable (renewable and refuse) energy and generate nega-energy. This paper covers three research examples of this type of sustainability: (1) use of air-to-earth heat exchangers, (2) computer control of heating and cooling of the building (via heat pumps and heat-recovery devices), and (3) design control of energy ...
