Sustainable Steam: Jönköping Energi’s HISS Project and its Impressive Results

In 2023, the Swedish power plant Jönköping Energi initiated a project that enabled them to increase their boiler load with biofuel. The outcome of that project was a significant increase in heat and electricity production. This however significantly increased their need for sootblowing. Introduction The project that enabled the green transition to more sustainable fuels was finished in the year of 2022. Doing an analysis of that project, Jönköping Energi concluded that they had increased their heat generation by 23 GWh more heat that reduced the need for more expensive fuels and 4 GWh increased electricity production. After the project that enabled the forementioned load increase, Jönköping discovered that even though they had to be sootblowing more as a consequence of increasing their boiler load, there was an add-on solution to their sootblowers that could save them time and steam for each cycle. The High Impact Sootblowing System (HISSTM). Since 90% of the cleaning effect is done by the initial [...]

Meet Andreas Aspell, our new Sales Manager

This bright new star shines bright in the office! Andreas Aspell worked with Heat Management as a Service Engineer, servicing our customers Infrasound cleaners. He left to pursue his studies and after concluding them, he began working in sales. We thought it was high-time to sit down and have an interview with Andreas to ask him about his new role. We consider ourselves lucky to have him returning to us. As the brand new Sales Manager for Canada and the USA. Welcome back Andreas! Q: What does it mean to be a Sales Manager for Heat Management? A: I see my role as being the Commercial Project manager. I pursue deals where implementing our technologies makes economic and environmental sense. With the customers, I gather the relevant process information that condensates to a business case with the help of our excellent organisation! Q: What do you enjoy most about your work? What motivates you? A: The variety of customer processes [...]

Johan Holmér’s Amazing Recap from BLRBAC 2023

In this article Johan Holmér gives a recap from his presentation at BLRBAC. He explains how the old ways of wasting the pulp and paper mill's resources prevents the process of streamlining production and lowering emissions.

Acoustic Cleaning: A Step to Constant Boiler Availability

Plugging and reduced heat transfer When being exposed to fouling, heat-transferring surfaces lose effectiveness over time due to scaling and buildup. This keeps power boilers from reaching their full potential. To unlock the potential of the boiler, it requires cleaning. One way that most plants around the world do this is by manually cleaning the desired area during a designated stoppage. This, however, poses a major loss in energy production. In this section we present three plants that had major issues with this before implementing acoustic cleaning. Click on their name to download an in-depth case study: Mälarenergi, Kraftvärmet Block 6: A Swedish waste-to-energy plant that had to stop their boiler operation, to sandblast the economizer every 3-6 months. Sandviksverket, Växjö: A Swedish CFB boiler, fuelled by biomass, that reduced their sootblowing steam consumption by 50% in the air preheater and economizer. The acoustic cleaner also fully eliminated the need to sootblow in the catalyst. EEW Delfzijl, Holland; [...]

Unveiling the Silent Culprit: Increased Fuel Consumption due to Fouling

The combustion boiler is at the heart of many operations. Whether it’s a power boiler operating in a combined heating plant or a recovery boiler in a pulp and paper mill. They enable processes to run smoothly and efficiently if maintained right. The boilers have a universal enemy that not only affect their efficiency but also the bottom line– fouling. One of the most overlooked consequences to heavy fouling Is increased fuel consumption. It is therefore important to mitigate the issue before the consequences get unbearable. Why does fuel consumption increase due to fouling? The overall performance of the boiler relies heavily on efficient heat exchange. The heat must flow from combustion chambers to water, generating steam that is essential for different processes in the combustion plant. The deposit buildup on boiler surfaces disturbs the heat exchange, this notion is well documented and fairly agreed upon. The hidden culprit though, is that in order to maintain the same steam [...]

Revolutionizing Fuel Analysis for Pulp and Paper mills: Heat Management’s Newest Tech Acquisition

The Acospector takes a whole new approach on process optimization and fuel analysis. With various software packages the impossible has become possible with this technology that enables analysis that can help users to avoid unwanted process modes. Wave Impact Heat Management AB and The Packaging Greenhouse AB has in a joint venture strategically acquired the technology to expand their portfolio, to offer their respective customer bases optimized operations. What is the Acospector? The groundbreaking technology was developed by Acosense, renowned for their expertise in fuel analysis. Although the company is no longer in operation, Heat Management sees the immense value of the past flagship product of Acosense. The hardware is installed on the customers pipes where the fuel is passing through. With unprecedented non-disruption to the customers production cycle. The solution does not require any boiler shutdown to be installed and commissioned, it seamlessly integrates in the customers infrastructure. Through acoustic signals, measurements are collected that is later analysed within [...]
