8 HRS HEAT EXCHANGERS : EXPERTS IN DIFFICULT HEAT TRANSFER APPLICATIONS
HRS Heat Exchangers are global pioneers of thermal technology , offering unique and innovative heat transfer solutions since 1981 . Heat Exchanger World had the pleasure of speaking with Mr Arnold Kleijn , European Sales Director , and Mr Matt Hale , Global Key Account Director , at HRS Heat Exchangers , about their cutting-edge scraped surface heat exchanger range and focus on the renewables market .
16 HEAT EXCHANGER FOULING IN PRACTICE – UNDERSTAND & MITIGATE PART 7 – HEAT EXCHANGER MONITORING
In this series of articles we will look at how heat exchangers foul , how to understand the root causes of fouling , and how to mitigate the impact of fouling .
18 ECONOMISERS FOR HEAT ENERGY RECOVERY & TRANSFER
Heat energy is critical to the chemical processing industry and heat recovery and reuse are central to the energy management process . Turnbull & Scott design engineers work closely with process engineers from the industry to support this .
20 GEA HEAT PUMPS PAVE WAY TO DISTRICT CLIMATE NEUTRALITY BY 2035
By supplying two heat pumps , GEA is helping the city of Lemgo on its way to achieving climate neutrality by 2035 . The GEA technology will generate heat from the effluent of the city ’ s wastewater treatment plant , waste heat from a large combined heat and power ( CHP ) plant and from the River Bega .
23 CLADDING APPLICATIONS IN SHELL AND TUBE HEAT EXCHANGERS
Weld overlay and cladding apply protective metallic layers to substrates , enhancing corrosion resistance and cost-effectiveness by using cheaper base metals . This method ensures material strength and thermal conductivity while exploring design , fabrication , inspection , and in-service aspects , replacing high-alloy materials in component fabrication .
26 ADVANCED SUPER-DUPLEX TUBE TAILORED FOR ACIDS
SAF™ 3006 is a high-alloy duplex stainless steel tailored to enhance corrosion resistance in acidic and caustic environments . The new alloy , an upgrade to traditional super-duplex stainless steels , adds to Alleima ’ s growing duplex portfolio . The main application is heat exchangers in the chemical and petrochemicals industries .
28 JOIN US IN ROTTERDAM : HEAT EXCHANGER WORLD EUROPE 2024
On 13 & 14 November , Heat Exchanger World Conference and Expo Europe will be held at AHOY Rotterdam . Here is a sneak peak at what you can expect for our premier European event !
30 DYNAMIC DUPLEX MATERIALS : STRONG AND SUSTAINABLE
Projections indicate a significant rise in duplex stainless steel usage due to its strength , low maintenance , and resistance to pressure , corrosion , and erosion . It ’ s favoured in process industries and architecture for its weight-to-strength ratio . Moreover , its appeal grows with the expansion of 3D printing to duplex grades .
35 Innovative solution to indirect heating in High-Pressure-Acid-Leach Process ( HPAL )
The following article explores the application of self-cleaning fluidized bed heat exchangers as an ideal solution for the indirect heating of laterite nickel slurry in High-Pressure-Acid-Leach ( HPAL ) plants .
