The challenge
Biostoom Oostende is a Waste-to-Energy plant in Belgium that generates heat and electricity by incinerating non-recyclable industrial waste, while fully complying with European emission standards.
A collaboration was initiated with Lhoist to drive continuous improvement, aiming to enhance both boiler performance and Flue
Gas Treatment operations.
The first objective is to address periodic SO2 inlet peaks associated with seasonal or sudden changes in fuel composition.
The second is to reduce fouling in the furnace and heat exchangers, thereby enhancing plant safety, reliability, and efficiency
The Lhoist solution
Sorbacal® Heat is a new product family specially engineered for direct injection into furnaces at 850 – 1050 ºC. The sorbent is tailored to each customer’s application (fuel type / ashes / configuration) and requirements.
At Biostoom, the dual functionality of acid gas abatement and boiler anti-fouling were provided. This was supported by robust technical assistance to ensure optimal sorbent conveying and dispersion, including the use of CFD modelling, expert consultancy, and Lhoist’s proprietary equipment and technologies to enhance dosing precision and product distribution within the boiler.
The success of this solution was made possible using Sorbacal® Heat and the close collaboration between Lhoist and Biostoom.
It’s not the how or the what but the Who that is so important to make something work.
