Revelando al culpable silencioso: mayor consumo de combustible debido a la suciedad

La caldera de combustión está en el corazón de muchas operaciones. Ya sea una caldera de potencia que opera en una planta de calefacción combinada o una caldera de recuperación en una planta de celulosa y papel. Permiten que los procesos funcionen sin problemas y de manera eficiente si se les da el mantenimiento adecuado. Las calderas tienen un enemigo universal que no solo afecta su eficiencia, sino también los resultados financieros: la acumulación de incrustaciones (fouling). Una de las consecuencias más pasadas por alto de las incrustaciones graves es el aumento en el consumo de combustible. Por lo tanto, es importante mitigar el problema antes de que las consecuencias se vuelvan insoportables. ¿Por qué aumenta el consumo de combustible debido a las incrustaciones? El rendimiento general de la caldera depende en gran medida de un intercambio de calor eficiente. El calor debe fluir desde las cámaras de combustión hacia el agua, generando vapor que es esencial para diferentes procesos en la planta de combustión. La acumulación de depósitos en las superficies de la caldera perturba el intercambio de calor; esta noción está bien documentada y es bastante aceptada. Sin embargo, el culpable oculto es que, para mantener el mismo vapor [...]

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 [...]

Why Lignin Extraction Usually Comes with a Catch 

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. [...]

Hacer que las fábricas de pasta de papel sean más sostenibles

En las plantas de celulosa, mantener limpias las superficies internas de transferencia de calor de las calderas de recuperación requiere mucha energía y puede limitar la capacidad de producción de toda la planta. Sin embargo, al reducir la cantidad de vapor utilizado en los sistemas de soplado de hollín por vapor, las plantas de celulosa y otras instalaciones pueden volverse más eficientes energéticamente y sostenibles, al tiempo que mejoran la disponibilidad de la caldera.
