The combustion boiler is at the heart of many operations. Whether it’s a power boiler operating in a combined heating plant or a recovery boiler in a pulp and paper mill. They enable processes to run smoothly and efficiently if maintained right. The boilers have a universal enemy that not only affect their efficiency but also the bottom line– fouling. One of the most overlooked consequences to heavy fouling Is increased fuel consumption. It is therefore important to mitigate the issue before the consequences get unbearable.   Why does fuel consumption increase due to fouling? The overall performance of the boiler relies heavily on efficient heat exchange. The heat must flow from combustion chambers to water, generating steam that is essential for different processes in the combustion plant. The deposit buildup on boiler surfaces disturbs the heat exchange, this notion is well documented and fairly agreed upon. The hidden culprit though, is that in order to maintain the same steam [...]

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 [...]
