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, [...]

Heat Management Landed 3 new Purchase Orders During the Summer of 2024!

Introduction During the summer vacation, we have kept ourselves busy! Our salespeople and project teams have worked cleverly during the warmer months, bringing in more exciting opportunities. This growth in our future references will allow us to expand as a company and keep adding value to both new and recurring customers who explore the rest of our solutions portfolio. The following purchase orders have come through this summer: High Impact Sootblowing System (HISS®) July: A pulp and paper mill in Brazil Carryover Early Warning System July: A pulp and paper mill in Sweden. A recurring customer who also has HISS® Infrasound cleaning August: A Waste-to-Energy plant in Germany, Steinmüller Engineering provides another infrasound cleaner, which will mark the end-customer’s fifth Infrasound cleaner. Brazil Our new Brazilian customer ordered HISS® in late July. This second HISS® project in Brazil will be an essential reference for Heat Management in the South American market. The project's goal is to save steam for the [...]

Mitigating NOx Penalties: The Role of Heat Management’s Solutions

NOx penalties and why it is essential to understand them. Nitrogen Oxides (NOx) represent a significant environmental challenge, primarily due to their harmful impacts on air quality and contribution to the formation of ground-level ozone and acid rain. Regulatory bodies worldwide have implemented stringent NOx emission standards, leading to the imposition of penalties on facilities that exceed these limits. This article explores the phenomenon of NOx emissions, their environmental impacts, and how Heat Management's patented High Impact Sootblowing System (HISS®) and Infrasound cleaning can aid facilities in reducing these emissions and associated penalties. The Challenge of NOx Emissions Nitrogen Oxides are a group of gases primarily produced during combustion processes at high temperatures. NOx emissions concern various industries, particularly those relying on combustion plants, such as power and heat plants, pulp mills, and marine boilers. The primary sources include vehicles, industrial processes, and energy production, with power- and recovery boilers in the industrial sector being significant contributors. The environmental impact [...]

Achieve Sustainable Production Goals in the Pulp and Paper Industry with HISS

The Need for Sustainable Solutions in Pulp and Paper Production The pulp and paper industry, vital for providing essential products to society, is undergoing a transformation towards sustainability. As environmental concerns arise and regulatory pressures increase, companies in this sector seek innovative solutions to minimize their environmental footprint. A solution is the High Impact Sootblowing System (HISS®), changing how pulp and paper mills handle sootblowing. By harnessing the power of HISS®, companies are optimizing their production processes and making significant strides toward achieving their sustainability goals. HISS® is Changing Sootblowing in Pulp and Paper Mills Traditional sootblowing is stuck in the same pattern as it always has been. Meaning, sootblowing in both the entry and exit stroke wastes nearly 50% of the steam since 90% of the cleaning effect is done at the entry stroke. HISS®, however, uses advanced automation and impactful cleaning methods to improve boiler performance, save energy, and reduce emissions. It cleans efficiently by sootblowing in one [...]

Two more HISS orders from one of the largest pulp and paper conglomerates in the world.

One of the largest pulp and paper manufacturers in the world has decided to invest in Heat Management’s solutions. The manufacturer has previously ordered Infrasound cleaning to their mill in Belgium and has since recognized an efficient way to conduct their steam sootblowing operations in the Nordics. Traditional sootblowing Most recovery boilers are delivered with traditional control systems for their sootblowers. These systems are cheap to buy but very expensive to operate, racking up millions of EUR in wasted energy. Here, Heat Management disrupts the paradigm and combines patented system controls and innovative valve control solutions, to deliver the earlier impossible solution of Sootblowing more, with less steam. The High Impact Sootblowing System has become renowned for its way of allowing users to save a guaranteed amount of 30% sootblowing steam consumption, often even surpassing the guaranteed values. A Swedish pulp mill. In 2023, the order for installing HISS® for a large mill in Sweden was received. The recovery boiler [...]
