Transitioning to liquid low-carbon fuels is an important part of of the CO2 decarbonisation journey.

 

Many of these fuels, which are created from different types of raw materials, are already available and will contribute significantly to climate protection together with modern oil-fired condensing boilers.

 

Until now, the challenge has been getting biofuels to the boiler. Danfoss has taken up this challenge, by making its pumps and nozzles biofuel ready.

Solving the corrosion challenge

Traditional pumps often contain copper or copper-containing metals (also known as non-ferrous or red-metal). Independent research has shown that contact between parts made of non-ferrous metals and biofuels should be avoided. When biofuel contacts non-ferrous metals, it oxidises and polymerises. The fuel’s acid content increases and it becomes more corrosive. The fuel will then react with these metal parts in the pump, which can adversely impact pump performance, cause leakage or lead to the safety function (e.g., solenoid valve) failing. 

Additionally, the combination of non-ferrous parts and higher temperatures harms the biofuels, because of the internal circulation process. The fluid passes these parts several times, thereby reducing the biofuel’s stability and causing the fuel to degrade. To prevent this from happening, manufacturers would have to replace the parts yearly or every second year.

Ina Corneliussen, Product Manager, Burner Components, explains how the new biofuel ready pumps address this challenge. “We have been working with biofuels for over 15 years, and we have always prioritised safety.  That’s one of the reasons we’ve changed the non-ferrous components in our Bio30 pumps to make sure all product components are biofuel compatible. And our well-known mechanical shaft sealing secures the highest quality and helps eliminate the risk of oil leakage and product malfunction.”

TUV-certified to work with biofuels

Danfoss has conducted extensive in-house and field testing to develop our product portfolio, working closely with customers and independent competence centers to ensure the components’ compatibility with biofuels. After successful product testing, we acquired a TUV certification in 2021. “Some of the largest OEMs are already using our new pumps and have approved them for their applications, and we can see that more of our existing customers are interested in switching to Bio30 pumps. For example, effective July 1, 2022, France has changed its regulations to only install Bio30 ready products in their boilers,” comments Stefan Spornberger, Senior Quality and Application Manager, Burner Components. “We’re pleased to support our customers decarbonisation efforts by providing them with best-in-class solutions for transitioning to carbon-neutral energy sources.”

Nozzles ready for the HVO market

The expanded portfolio of bio products also includes HVO nozzles, which have been adjusted and are now fully compatible for biofuel use. These nozzles are designed for domestic oil burners in the UK and enable them to use hydrotreated vegetable oil (HVO) derived from used cooking oil or non-food vegetable oils. 

Removing barriers to the net zero transition

By developing biofuel ready components, Danfoss aims to support the transition to low-carbon liquid fuels. “Over the past 75 years, Danfoss has built a reputation within the industry for designing and manufacturing high-quality, reliable products. And our customers can expect that same standard from our new line of bio products,” says Ina Corneliussen.

And we will continue to develop our Bio portfolio to design products that can enable boilers to run on higher contents of biofuel.”

  • The Bio10 and Bio30 pumps are compatible with heating oil mixed with 10% and 30% biodiesel (FAME and UCOME)
  • The Bio pumps feature state-of-the-art mechanical shaft sealing that reduces the risk of oil leakage
  • With the Bio30 pump, biofuel has no contact with non-ferrous metal
  • The Bio pumps and HVO nozzles have 100% capacity and are performance tested
