The total capacity of the Andritz High Energy Recovery Boiler (HERB) is about 50% higher than of any other recovery boiler in operation today worldwide, reaching a black liquor firing capacity of 11,600 t/d of dry solids. The maximum daily green electricity production of the boiler is equivalent to the average daily electricity power need of a European city of one million inhabitants.

The boiler will feature state-of-the-art solutions for optimizing power-to-heat ratios by operating at higher pressures and temperatures than conventional boilers. This allows pulp mills to maximize their environmental-friendly power generation.

Start-up is scheduled for the second quarter of 2016.
