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, [...]

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 (HISS®). Since 90% of the cleaning effect is done by the initial [...]
