PetroBio helps Renova replace fossil fuels with renewables

In an effort to reduce climate-impacting emissions, the Swedish waste power plant Renova in the district Sävenäs, upgrades its eight start-up and support burners to be able to operate with biofuel instead of fossil oil. Thanks to this adaptation, fossil emissions are reduced by approximately 960 tonnes of CO₂ annually.

The primary task of the start-up and support burners is to heat Renova's four waste heat boilers after the yearly auditing or when needed. An example is if the waste is very wet. Then a support burner is needed for the temperature of the waste heat boilers to reach the correct temperature according to the waste directive, ie 850C ° for 2 seconds.

The task of updating the existing combustible oil system for operation with RME oil is performed by PetroBio. Since RME is more aggressive than fossil oil, several different parts need to be replaced and the burners adapted.

– The waste power plant currently consumes about 550 cubic meters of combustible oil per year. We are incredibly proud to be part of converting it to biofuel, says Johanna Lindén, CEO Petro Bio. We delivered our first burners to Renova as early as 1972, and now we are making a joint journey towards a more sustainable future here in Gothenburg.

At the Renova waste power plants, approximately 550,000 tonnes of waste are combusted per year. The generated heat is converted to a third of Gothenburg's district heating, making Renova the largest supplier of district heating in Gothenburg. The plant also produces about 5% of Gothenburg's electricity needs.

The transition from fossil oil to biooil in the start-up and support burners is an important step in Renova's ambition to minimize fossil use and actively contribute to long-term sustainable development.

– We feel very safe with PetroBio's delivery. They supply trouble-free burners, regular service delivery and 24-hour on-call operations. And their solid experience with flame combustion technology and biooil makes the transition from fossil to renewable energy painless and safe, says Malin Bruhn, process engineer at Renova.
