Dunphy burners play key role in Diageo’s biofuel facility

A key role in reducing CO2 emissions by 56 000 t a year at a Diageo distillery are five specially engineered biofuel burners from Dunphy Combustion.

Burners for the boilers in the £65 million bioenergy facility at Diageo’s Cameronbridge Distillery in Fife are to be supplied by Dunphy Combustion. Being developed in partnership with Dalkia, the facility will integrate on a commercial scale sustainable technologies, including anaerobic digestion and biomass conversion. CO2 emissions from the site are expected to be reduced by about 56 000 t a year.

Dunphy is supplying five highly engineered burners for the project. All will burn biogas and two can also burn natural gas.

This bioenergy facility will generate renewable energy from the spent wash produced during distillation. The wash is a mixture of wheat, malted barley, yeast and water, which is separated into liquid and dried solids. Liquid residues are converted by anaerobic digestion into biogas. The dried solids form a biomass fuel source.

The control systems on the five burners will monitor changes in calorific value, moisture content and other parameters and adjust combustion to maximise efficiency.
