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.\u00a0<\/span><\/em><\/p>\n

The newly formed sustainability partnership<\/b><\/h2>\n

Sappi Gratkorns goal was to reduce their steam consumption and therefore reduce their annual cost of lowering their environmental impact.\u00a0 In the year 2021, Sappi Gratkorn entered into a sustainability partnership with Heat Management to investigate ways of furthering their eco-effective journey.<\/span><\/p>\n

It was determined that Heat Managements <\/span>High Impact Sootblowing System (HISS)\u00ae<\/sup>) <\/span><\/a>\u00a0was 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 <\/span>HISS\u00ae<\/sup><\/span><\/a> operation comparable to power boilers with various fuels like biomass and waste.<\/span><\/p>\n

Sappi Gratkorn is renowned for streamlining its mill for a better environment. Other than implementing <\/span>HISS\u00ae<\/sup><\/span><\/a>, they have driven several initiatives regarding renewable energy and reducing waste. Furthermore, they have been awarded multiple awards for their continuous striving for green operations.\u00a0<\/span><\/p>\n

The calculated action that lead to less waste<\/b><\/h2>\n

The mill has 13 sootblowers in the superheater. They wanted to reduce their steam consumption and stabilise their sootblowing steam flow to avoid pressure variations on the steam net. The environmental investment in<\/span> HISS\u00ae<\/sup><\/span><\/a> was therefore a calculated action to further evolve their operations.\u00a0<\/span><\/p>\n

The benefits for the environment by saving steam is linked to conserving more energy and reduced fuel- and water consumption when producing the steam. After installing <\/span>HISS\u00ae<\/sup><\/span><\/a>, Sappi Gratkorn concluded that they had saved <\/span>43% of their annual sootblowing steam and had halved the time for their cleaning cycles<\/b> which is higher than the initial guarantee from Heat Management.\u00a0<\/span><\/p>\n

Thomas Ladinek, Production Engineer<\/b> says<\/span>, \u201cSappi Gratkorn\u2019s continuous strive for improvement, including the optimized steam sootblowing technology HISS\u00ae<\/sup>, makes us highly competitive in unlocking the power of trees to make every day more sustainable and to continue solving sustainability challenges with innovative partners.\u201d<\/span><\/i>\"\"<\/span><\/i><\/p>\n<\/blockquote>\n

Comparing the costs of implementing the system and their savings in annual costs linked to steam sootblowing, Sappi Gratkorn had a return on investment in less than a year after commissioning. Due to increasing the load of their boiler, their savings can even go beyond what was initially expected from the savings of steam costs. This is what Heat Management means with the slogan, \u201cBeyond Technical Specification\u201d.\u00a0<\/span><\/p>\n

HISS\u00ae<\/sup> \u2013 Sootblow more, with less steam.<\/b><\/a><\/h2>\n

The patented High Impact Sootblowing System (HISS\u00ae<\/sup>) disrupts the \u201chow we have always done it\u201d approach to energy intensive steam sootblowing. By operating the existing steam sootblowing system in a smarter and less wasteful way, half the steam and half the time can be saved. This leads to increased boiler efficiency, availability, and lifetime without installing any new sootblowers or rebuilding the boiler.<\/span><\/i><\/p>\n
