Verified HISS Results from Four Recovery Boilers

Heat Management's HISS (High Impact Sootblowing System) has demonstrated reductions of over 30% in sootblowing steam consumption at four black liquor recovery boilers, while maintaining or increasing boiler load. These results are based on actual operating data collected directly from the facilities, comparing recovery boiler load and sootblowing steam consumption before and after HISS implementation.   Facility 1 – 31% Reduction in Sootblowing Steam Consumption Following the implementation of HISS, the recovery boiler achieved: Boiler load: Increased by 6.3%, from 1,200 to 1,275 tDS/day. Sootblowing steam consumption: Reduced by 31%, from 14.5 to 10 t/h.   Facility 2 – 30.4% Reduction in Sootblowing Steam Consumption The second recovery boiler achieved significant steam savings alongside increased boiler load: Boiler load: Increased by 4.15%, from 2,050 to 2,135 tDS/day. Sootblowing steam consumption: Reduced by 30.4%, from 21.7 to 15.1 t/h. Facility 3 – 33.3% Reduction at Stable Boiler Load At the third recovery boiler, HISS delivered substantial steam savings while maintaining the [...]

Holmen Workington increases sustainable power generation with HISS

  Holmen Paper Mill in Workington, UK, identified an opportunity to cost-effectively improve the efficiency, lifetime and availability of its biomass-fired 150 MW BFB boiler. With an absolute return-on-investment guarantee and without installing more machines, boiler electrical efficiency increased by 0.62 percentage points while boiler tube erosion from sootblowing impingement was avoided. The additional renewable power generation corresponds to approximately 2,065 tonnes of avoided CO₂ emissions per year compared with equivalent generation from natural gas.     Improving sootblowing efficiency at Holmen Workington Holmen’s Workington mill is certified according to ISO 50001 and has been awarded EcoVadis Platinum, placing it in the top 1 % of companies rated by EcoVadis. Energy efficiency, water savings and reliable operation are therefore natural priorities for the mill. Heat Management engineered, constructed, installed and started up HISS® Advanced to improve the existing sootblowing system in November 2025. The main objective was to reduce condensate impact on boiler tubes and lower steam consumption during sootblowing, [...]

Revolutionizing Sootblowing: Our New Multi-Position Actuator

Revolutionizing Sootblowing: Our New Multi-Position Actuator For years, the steam valves on sootblowers have relied on mechanical opening and closing mechanisms. While these solutions have served the industry well, they are subject to wear over time, which can compromise operational reliability and increase maintenance costs. In many plants, operators have turned to direct control of steam valves as an alternative. However, this approach has traditionally been limited to colder parts of the boiler, where cooling steam flow is not required. In hotter sections, the need for a cooling steam flow is critical to protect the lance from extreme temperatures. This limitation has made modernization a challenge. At Heat Management, we have been working for several years to rethink how sootblowers can operate more efficiently. Our goal has been to reduce steam consumption, optimize the cleaning process, and increase overall plant availability. Today, we are proud to introduce a new multi-position actuator that takes these improvements to the next level. [...]

Heat Management featured in “Dagens Industri”

Below is a translated version of the article in Dagens Industri. From cost to impact: Heat Management drives environmental change in the industry The energy industry is constantly transforming in its pursuit of sustainability and increased efficiency. Johannes Holmberg, CEO of Heat Management, emphasizes replacing inefficient and environmentally harmful practices still used for industrial boilers and incinerators. - They are bottlenecks that hinder both production rate and positive sustainability development. Therefore, innovative solutions are required to meet future requirements.   The growing need to promote sustainability and reduce emissions is increasing, while global guidelines and requirements from world organizations for the environment are tightened. This is a challenge for the energy sector, says Johannes Holmberg, CEO of the cleantech company Heat Management. He notes that this is particularly noticeable in industries such as paper and pulp manufacturing, where outdated working methods and systems that are still used in production are a brake on efficiency and reduced environmental impact. Yet many producers [...]
