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 [...]

Sappi Gratkorn Implements Overlapping Sootblowing Technology to Lower Environmental Impact

Sappi Gratkorn is a paper mill in Austria that produces high-quality multi-coated paper. The mill has been in operation for over a century. In recent years, the company Sappi and their respective mills have been investing in developing their facilities to reduce their environmental impact. The newly formed sustainability partnership Sappi Gratkorns goal was to reduce their steam consumption and therefore reduce their annual cost of lowering their environmental impact. In the year 2021, Sappi Gratkorn entered into a sustainability partnership with Heat Management to investigate ways of furthering their eco-effective journey. It was determined that Heat Managements High Impact Sootblowing System (HISS®) was an appropriate solution to implement into the boiler's superheater, in order to achieve more sootblowing with less steam. Sappi Gratkorn, like most red liquor recovery boilers, operates the steam sootblowing in separate cycles. This makes the HISS® operation comparable to power boilers with various fuels like biomass and waste. Sappi Gratkorn is renowned for streamlining its [...]

The Swedish Energy Agency recognizes the potential in Heat Management’s CleanTech Solutions

CleanTech for Pulp and Paper Mills with Financing From the Swedish Energy Agency Heat Management has been at the forefront of revolutionizing the development of fouling prevention in industrial boilers. CleanTech is our passion and to push our products and the value for customers beyond technical specification. By setting the standard for boiler performance with patented solutions, and not being content with how boiler cleaning has been done in the past we help the industry to reach a new level. This has now been recognized by the Swedish Energy Agency and an initiative to help pulp and paper mills invest in modern CleanTech solutions has been initiated. The need to optimize boiler cleaning operations A recovery boiler has heat transfer surfaces inside that are exposed to ashes in the flue gas. It is desirable to keep the fouling rate as low as possible to be able to operate the boiler for as long time per year as possible. It is [...]

Why Lignin Extraction Usually Comes with a Catch

Many pulp and paper mills are looking for ways to compensate for the environmental impact of their operations while reaching global and internal sustainability goals. One common approach is enabling the possibility to replace oil as a building block in the production of high-value products with lignin. A natural fiber in almost every living plant, lignin plays a large role in wood’s ability to retain its characteristic stiffness and resiliency against decay. Not only does lignin present amazing opportunities to replace fossil-based materials with renewable materials, but it can also decrease the discharge of pollutants. However, lignin extraction comes with a catch. The high costs and safety risks of lignin extraction Before lignin can be put to use as an alternative building block, it must first be extracted from a by-product of the Kraft pulping process called Black Liquor. In addition to lignin, Black Liquor consists of hemicellulose and inorganic compounds. Black Liquor is used to supply pulp for [...]

Incredible Results found at Zellstoff Pöls AG

Evaluation of environmental investment “HISS™” at Zellstoff Pöls AG In 2020, Zellstoff Pöls AG made the investment to commission a sootblowing solution that were to be installed on all 86 of their sootblowers. The system had its startup in the beginning of 2021 and the project evaluation has now been finalized and it revealed incredible results. The High Impact Sootblowing System ™ (HISS ™ ), developed by Heat Management has garnered wide popularity in the Swedish pulp and paper mill industry. The technology has become a market leader in Sweden. Cellulose Pöls AG are the first in Austria to implement the system in their mill, and they are beginning to reap the benefits. The potential with implementing HISS ™ is beyond technical specification but some potential benefits nearly include halving the time and steam used in the sootblowing process and prolonging equipment life. The goal with the installation of HISS ™ was to reduce sootblowing steam consumption by at least [...]

Three new HISS™ orders for pulp mills!

Half steam ahead! Three pulp mill customers are tired of their sootblowing systems wasting half the steam and half the time. The mills come from two international P&P groups and decided recently to partner up with Heat Management, to take their chemical recovery process beyond technical specification. The innovative solution will be used to reach the mill sustainability targets, by reducing: Water consumption, m3/ADt Energy consumption, MWh/ADt Emissions, tCO2e/ADt Heat Managements’ disruptive and market leading High impact Sootblowing System (HISS™) always come with absolute process guarantees for availability and energy savings. These measurable key performance indices facilitate return on investment calculation and the guarantees minimize project risk. The guaranteed sustainability benefits and subsequent significant financial savings lead to short payback time, with the risk being carried by Heat Management. Together, the three pulp mills will save a minimum of 100 GWh of steam, 130 000 m3 water and 6 000 tCO2e per year in their three black liquor recovery boilers. [...]
