Die Enthüllung des stillen Verursachers: Erhöhter Kraftstoffverbrauch durch Verschmutzung

Der Verbrennungskessel bildet das Herzstück vieler Betriebe. Ob es sich nun um einen Kraftwerkskessel in einem Heizkraftwerk oder einen Rückgewinnungskessel in einer Zellstoff- und Papierfabrik handelt. Sie ermöglichen einen reibungslosen und effizienten Ablauf der Prozesse, sofern sie richtig gewartet werden. Die Kessel haben einen universellen Feind, der nicht nur ihre Effizienz, sondern auch das Endergebnis beeinträchtigt – die Kesselverschmutzung. Eine der am meisten unterschätzten Folgen starker Verschmutzung ist der erhöhte Brennstoffverbrauch. Es ist daher wichtig, das Problem zu entschärfen, bevor die Folgen unerträglich werden. Warum steigt der Brennstoffverbrauch durch Verschmutzung? Die Gesamtleistung des Kessels hängt stark von einem effizienten Wärmeaustausch ab. Die Wärme muss von den Brennkammern zum Wasser fließen und Dampf erzeugen, der für verschiedene Prozesse im Verbrennungswerk unerlässlich ist. Die Ablagerungen auf den Kesseloberflächen stören den Wärmeaustausch; dieser Sachverhalt ist gut dokumentiert und weitgehend unumstritten. Der versteckte Übeltäter ist jedoch, dass zur Aufrechterhaltung desselben Dampfes [...]

Sappi Gratkorn Implements Overlapping Sootblowing Technology to Lower Environmental Impact

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 [...]

Warum die Ligninextraktion meist einen Haken hat 

Many pulp and paper mills are looking for ways to compensate for the environmental impact of their operations while reaching global and internal sustainability goals. One common approach is enabling the possibility to replace oil as a building block in the production of high-value products with lignin. A natural fiber in almost every living plant, lignin plays a large role in wood’s ability to retain its characteristic stiffness and resiliency against decay. Not only does lignin present amazing opportunities to replace fossil-based materials with renewable materials, but it can also decrease the discharge of pollutants. However, lignin extraction comes with a catch.   The high costs and safety risks of lignin extraction  Before lignin can be put to use as an alternative building block, it must first be extracted from a by-product of the Kraft pulping process called Black Liquor. In addition to lignin, Black Liquor consists of hemicellulose and inorganic compounds. Black Liquor is used to supply pulp for [...]

Incredible Results found at Zellstoff Pöls AG

Evaluation of environmental investment “HISS™” at Zellstoff Pöls AG In 2020, Zellstoff Pöls AG made the investment to commission a sootblowing solution that were to be installed on all 86 of their sootblowers. The system had its startup in the beginning of 2021 and the project evaluation has now been finalized and it revealed incredible results. The High Impact Sootblowing System ™ (HISS ™ ), developed by Heat Management has garnered wide popularity in the Swedish pulp and paper mill industry. The technology has become a market leader in Sweden. Cellulose Pöls AG are the first in Austria to implement the system in their mill, and they are beginning to reap the benefits. The potential with implementing HISS ™ is beyond technical specification but some potential benefits nearly include halving the time and steam used in the sootblowing process and prolonging equipment life. The goal with the installation of HISS ™ was to reduce sootblowing steam consumption by at least [...]

Three new HISS™ orders for pulp mills!

Half steam ahead!  Three pulp mill customers are tired of their sootblowing systems wasting half the steam and half the time. The mills come from two international P&P groups and decided recently to partner up with Heat Management, to take their chemical recovery process beyond technical specification. The innovative solution will be used to reach the mill sustainability targets, by reducing: Water consumption, m3/ADt Energy consumption, MWh/ADt Emissions, tCO2e/ADt   Heat Managements’ disruptive and market leading High impact Sootblowing System (HISS™) always come with absolute process guarantees for availability and energy savings. These measurable key performance indices facilitate return on investment calculation and the guarantees minimize project risk. The guaranteed sustainability benefits and subsequent significant financial savings lead to short payback time, with the risk being carried by Heat Management. Together, the three pulp mills will save a minimum of 100 GWh of steam, 130 000 m3 water and 6 000 tCO2e per year in their three black liquor recovery boilers. [...]

Making pulp mills more sustainable

In pulp mills, keeping the internal heat transfer surfaces of recovery boilers clean requires a lot of energy and can limit the entire mill’s production capacity. However, by reducing the amount of steam used in steam sootblowing systems, pulp mills and other plants can become more energy-efficient and sustainable, while improving boiler availability.
