Rotherham-based Dunphy Combustion has recently completed a state-of-the art, carbon-neutral, energy installation for a major dairy and cheese-making factory in Wels, Austria.
The system uses biogas extracted from the cheese whey.
Landfrisch Molkerei approached Dunphy's agent in Austria and asked Dunphy to turn the whey waste left over from the cheese making into fuel to power its steam processing plant.
Dunphy designed a dual gas-fired burner using mostly biogas extracted from the whey by an anaerobic digester.
Some 1.1Mm³ of biogas will be produced annually, which is equivalent to around 0.8Msm³ of natural gas. The burner will automatically switch to natural gas should the supply of waste- generated fuel be interrupted at any time.
Because of the biological process involved in producing the whey-based gas, its calorific value can vary, so the burner has been fitted with a fast-response fuel trim system , the Ratiotronic direct digital combustion control system. The touch-screen system ensures safe management of each fuel through a dedicated control channel.
