Watch: In Pursuit of Lesser Water Footprint
The new boiler, with its high efficiency and superior steam generation capacity, will enable the shutdown of one existing coal-fired boiler and two recovery boilers, resulting in a significant reduction in greenhouse gas emission, thus making mill operations more economical and sustainable. ANDRITZ will execute the project in co-operation with the Japanese EPC supplier, Kanadevia. The start-up is scheduled for 2028.
“We are very pleased that this new high-efficiency recovery boiler will make a significant contribution to reducing greenhouse gas emissions at the Ishinomaki mill. We aim to strengthen our international competitiveness by utilizing the learnings from this project at our other mills,” said Mr. Yoshinori Matsubara, Executive Officer, Head of Energy Business Div., Nippon Paper Industries.
“We greatly appreciate the trust that Nippon Paper Industries has placed in the ANDRITZ team and our technical solutions. Our approach to the supplied technology represents the best solution in terms of process and efficiency, and operation cost. We look forward to executing this project and to extending our collaboration in the future,” said Masato Tsuchitana, General Manager at ANDRITZ in Japan.

The new recovery boiler is designed for a capacity of 2,200 tds/d with steam parameters of 8.3 MPa and 505 °C. Designed for long operating periods, the state-of-the-art boiler features several automation and digitalization solutions. It has a high-dry solids concentrator with pressurized storage tanks used in the evaporation plant to increase the firing black liquor’s dry solids concentration, thereby maximizing recovery boiler efficiency. It also has an ash leaching system to remove chloride and potassium from the electrostatic precipitator’s ash while recovering sodium and sulfate to the chemical recovery cycle.
With this order, ANDRITZ once again demonstrates its strong global position as a supplier of state-of-the-art pulp mill technology focusing on environmentally friendly production.
