Siemens Energy and Heat Management have entered a strategic partnership to jointly contribute to a global reduction of the CO₂ footprint in the pulp and paper industry.
By exchanging innovations and further developing optimized steam sootblowing- and steam turbine control solutions, the companies intend to drive the transition to more sustainable, reliable, and affordable energy systems on a global scale. High Impact Sootblowing System (HISS) combined with SIPAPER Power Intelligence increases the output of sustainable power generation and decreases the need for fossil power generation.
Last year the common platform was developed to enable safe overlapping operation of sootblowers based on Simatic PCS7 SIPAPER DCS environment. The new agreement is the next step of our collaboration, where the common platform is still the basis of the collaboration. But this time serves a bigger purpose, to reduce the CO₂ footprint in the pulp and paper industry.
Pontus Linder, Product Manager at Heat Management, said:
“We see the HISS technology as a significantly important element in reducing the CO₂ footprint and to improve the sustainable electrical generation. The cooperation is a step in the right direction for the pulp- and paper industry. We are delighted to work with Siemens Energy together on innovations of the future.”
High Impact Sootblowing System (HISS) applies to a patented solution for optimizing sootblowers in industrial- and black liquor recovery boilers, which are generally operated non-stop to keep the flue gas path clean and to prevent fouling and sintering of accumulations on heat transfer surfaces. In many cases, the operation of the existing sootblower system is not enough, with resulting downtime for manual cleaning. The optimization can increase sootblowing capacity by 100% without installing more sootblowers or steam headers. By introducing a local control on each sootblower steam valve, existing sootblowers can be upgraded to one-way soot blowing without taking the boiler off-line and disrupting the chemical recovery process. During boiler shutdown, the control system is upgraded to achieve overlapping operation of sootblowers. The technology constitutes a step-change in sootblowing technology, doubling the capacity (starts per day) without installing more sootblowers or consuming more steam.
The HISS system offers unique flexibility when it comes to operating recovery boilers in the most sustainable and economical way.
By optimizing the sootblowers, the following can be obtained:
- Up to 50 % reduced steam consumption of the steam sootblowers
- Doubling the sootblowing frequency
- A combination of both
Regardless of utilization, HISS leads to a decrease in the CO2 footprint.
