By Matt Hale, International Sales and Marketing Director, HRS Heat Exchangers 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…

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…

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…

Since the first spiral heat exchanger was proposed back in the 19th century, they have become synonymous with the treatment of slurries and wastewater. However, in many situations the performance of a corrugated tube heat exchanger is equal to or better than that of a spiral design. Corrugated tube designs also provide a number of…
