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…

HRS Heat Exchangers, Booth 8512, WEFTEC 2019 HRS Heat Exchangers will highlight its extensive range of heat exchangers and treatment systems for wastewater and anaerobic digestion at the world’s largest annual water quality exhibition: WEFTEC, when it returns to Chicago, IL this September. In particular, HRS will address the prevention of fouling and how to…

HRS Heat Exchangers, Stand 220, Aquatech Mexico HRS Heat Exchangers will showcase highlights from its extensive range of heat exchangers and treatment systems for wastewater and anaerobic digestion at Aquatech Mexico in September, with a particular focus on energy efficiency and preventing equipment fouling. HRS’ heat exchangers are well established around the world in sectors…

Wastewater, sewage, effluents and sludge are useful sources of energy with the potential to heat (or in some circumstances cool) other products or materials in industrial processes. The DTR Series of double tube heat exchangers from HRS is designed to maximise direct (product-to-product) energy recovery from such low viscosity materials, allowing valuable heat to be…

Liquid and semi-liquid waste streams are an unavoidable aspect of many industrial processes, from energy production to food manufacturing; from chemical processing to wastewater treatment; systems which can reduce the volume and water content of such waste streams can not only cut disposal costs, but often turn a waste into a potentially valuable resource. Evaporation…

HRS Heat Exchangers, Stand G201, UK AD & World Biogas Expo HRS Heat Exchangers will showcase highlights from its extensive range of heat exchangers and treatment systems for anaerobic digestion at UK AD & World Biogas in July, with a particular focus on the benefits of removing water from biogas. If water enters a CHP…

There are a variety of tubular heat exchangers on the market, but for many applications corrugated tubes continue to be preferred over smooth ones. Matt Hale, International Sales & Marketing Director of HRS Heat Exchangers, explains why… While plate heat exchangers are still commonly used for simple viscous fluids such as water, milk and some…
