Nippon Paper Industries Co., Ltd. has selected international technology group Andritz to supply a new recovery boiler for its pulp mill in Ishinomaki, Japan. The scope of supply includes advanced automation and digitalization solutions for maximum use of the boiler's potential.

The value of the order will not be disclosed. It is included in Andritz's order intake for the Q2 2025.

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.

Andritz's scope of supply includes the following new equipment:
• A new recovery boiler 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.
• A high-dry solids concentrator with pressurized storage tanks is used in the evaporation plant to increase the firing black liquor's dry solids concentration, thereby maximizing recovery boiler efficiency.
• 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.
