At delfort\u2019s paper mill in Finland, the project aimed to support the decarbonization of steam generation while maintaining the reliability, responsiveness, and steam quality required for paper production. A key challenge was ensuring stable operation under demanding process conditions, including sudden load changes such as paper sheet breaks, which can cause rapid fluctuations in heat demand and waste heat availability. The solution also needed to provide steam at the temperatures required by the manufacturing process without relying on fossil-fuel boilers.<\/div>\n
To address these requirements, Turboden developed a customized Heat Upgrade system combining a Large Heat Pump (LHP) and a Mechanical Vapor Recompression (MVR) unit. The system recovers low-grade waste heat from the paper mill and upgrades it using CO\u2082-free electricity to produce more than 12 MWth of superheated steam at 3.4 barA, at temperatures ranging from 170\u00b0C up to 185\u2013190\u00b0C, with an attemperator controlling the final steam temperature delivered to the mill\u2019s network.<\/div>\n
The project demonstrates how high-temperature heat pumps can support the electrification of industrial heat and significantly reduce CO\u2082 emissions in energy-intensive industries.<\/div>\n
