Aughinish Alumina ordered a 25 MW high-pressure electrode steam boiler for its alumina refinery in Ireland. It will deliver 40 tons of high pressure steam per hour.

Norway’s Parat Halvorsen AS will supply a complete steam system with control panel, including a 450-kW superheater that will lift the steam temperature up to 530°F (277°C). The delivery also will include a circulation circuit with pumps and prefabricated pipes, a feedwater circuit, and a chemical and blowdown tank.

Scheduled to start operation in late 2023, the boiler will replace close to 10 percent of the current demand for steam at the site. The boiler also should help Aughinish Alumina avoid 5 percent of greenhouse gas emissions compared to conventional technology. According to Parat Halvorsen, its high pressure electrode steam boilers can reduce CO2 emissions from large industrial companies by replacing fossil fuel boilers with electrical steam production.
