Palm Paper Ltd., which operates the world’s largest paper mill for newsprint from its King’s Lynn site in the UK, was supplied with steam by two natural gas-fired fire-tube boilers.
In view of environmental and economic considerations, Palm Paper decided to build a combined cycle power plant (CCGT) to provide an independent supply of electricity and steam to the site. The combined cycle power plant was commissioned in spring 2018.
The new CCGT plant comprises the following main components:
- Gas turbine with 33 MW electrical generation capacity
- Additionally fired dual-circuit waste heat boiler with heat exchanger
- Turbo generator set with 12 MW electrical generation capacity
- High-pressure natural gas supply Pipeline.
- Due to the highly-efficient system used, Palm Paper’s CCGT power plant in King’s Lynn has an overall annual efficiency level of more than 80%.
This results in an annual saving of more than 100,000 tonnes of CO2. The total investment (CCGT plant incl. the high-pressure natural gas supply) was approximately EUR 60 million.
