International technology Group ANDRITZ has received an order from OKI Pulp & Paper Mills to supply the world’s largest recovery boiler for OKI’s new kraft pulp mill in Indonesia. Start-up is scheduled for the second quarter of 2016. The order value amounts to approximately 120 million euros.

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 tons of dry solids per day. 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. The order confirms the position of the ANDRITZ PULP & PAPER business area as one the world’s leading suppliers for high-energy recovery boilers.
