Choosing the Right Heat Exchanger for Food Processing
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 ...

What Are the Characteristics of Stainless Steel Corrugated Plate?
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 ...

CSIR - Division of Mining Technology Quality Assurance Department - South Africa - Case Study
Background The Ball-Tech Energy Ltd automatic heat exchanger tube cleaning system type BMS – 8" system was installed and tested on 1996 on an underground refrigeration machine. The refrigeration plant was operated for two periods of two months with and without the cleaning system in use. Results of the investigation showed clearly that the measured performance of the plant deteriorated by ...

The Continuous Pyrolysis Plant: The Right Opportunity
The continuous pyrolysis plant features a screw feeding sealing system, which can be observed as high heat exchange efficiency and capacity. Its electrical product is also impeccably controlled. It realizes zero emissions and may be fed with any fuel. The new air flowing to the reactor gets hotter the fuel. The finished goods are clean and odorless. It could also be accustomed to recycle waste ...

When is the Ambient Temperature Too Hot to Rely on Air to Air Heat Exchangers for Enclosure Cooling?
When you are looking for an efficient method for enclosure cooling, a heat exchanger is a good solution for a few different reasons. Not only is a heat exchanger energy efficient, but it allows you to maintain a completely closed loop enclosure cooling solution. The way a heat exchanger operates is by employing a heat pipe principle to exchange heat from an electrical enclosure to the outside. ...

Dry ice widely used in many fields to keep fresh & cold
Dry ice is solid CO2 -carbon dioxide with temperature of -78.5 degrees. In our life, we often see it, and the application field of dry ice is also very extensive. Following Qingdao Newtep will explain the application of dry ice in various fields: 1. Food industry Because of its extremely low temperature, dry ice can be used as refrigerant to preserve food and seafood transported by cold chain. ...

Fossil and Nuclear NDT Solutions for the Power Industry
Power generation means unleashing vast energy, transforming it, and harnessing it. Fossil fuel power plants tap into organic materials formed over the course of millions of years. Nuclear energy is an emissions-free source that comes from splitting atoms in a reactor to power industry and homes. When working with such colossal forces, it’s vital that the equipment and machinery used are ...

Corrugations best for efficiency in tubular heat exchangers
There are many different types of tubular heat exchanger on the market, such as annular space, double tube and multitube, as well as those with different geometries including the use of internal fins, dimples and corrugations. We have written several articles explaining why corrugated tubes are our preferred design option, but it is worth ...

HRS multipass RMP heat exchanger improves heat transfer for viscous materials
The HRS R Series of scraped surface heat exchangers is ideal for multitube scraped surface installations thanks to its helical scraper system which provides the ability to provide a large surface area with a very small footprint. We have now launched a new multipass version – the RMP Series – which further improves heat transfer for challenging viscous materials. Based on the R3 ...

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 ...

HRS helps AD plant tap into additional heat from existing CHP
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 ...

Assessing product properties for optimal heat exchanger performance
In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different. Understanding these properties ensures the correct heat exchanger is supplied. For example, high fouling materials may require a scraped-surface unit. Having adequate information will also ensure that the heat exchange process does ...

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 ...

Understanding and preventing heat exchanger fouling
When operating in exceptionally challenging conditions, or handling difficult materials such as sewage and wastewater sludges, even the best designed heat exchangers will be susceptible to fouling. Understanding the different types of fouling and what causes them will help engineers and operators pick the best type of heat exchanger for their particular application and keep it running in optimum ...

The Stubby Bitumen - Twisted Tube Heat Exchanger - Case Study
The Challenge Twisted tube designed heat exchangers are exceptionally difficult to clean. This particular fouling process is extra challenging due to the steam in the tube side which bakes the bitumen on to the shell side faster than other designs. This heat exchagner was brought to ABSOLUTE after a previous service provider was not successful in their attempt to clean it. When previously ...
