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, [...]
