John Thompson’s Package Boilers business unit recently designed and supplied three biogas-fired boilers for the winery and dairy industries.
Distell now operate a 2 t/h Redipac boiler, supplied via Veolia Water Technologies, at their Adam Tas winery in Stellenbosch and a 3.2 t/h Enviropac boiler, with a steam accumulator, for their distillery at Wellington. This particular boiler generates steam at a pressure of 20 bar for discharge directly into the accumulator vessel. Steam is drawn from the accumulator at a constant pressure of 10 bar for the whiskey distilling process, as and when required. Biogas is a by-product of this process.
In addition, Woodlands Dairy now operate a 4 t/h Redipac boiler as part of the expansion of their biogas plant in Humansdorp in the Eastern Cape.
Biogas is produced from the treatment of effluent using anaerobic digesters and can offset 10% to 25% of fuel requirements in the production of steam.
Several John Thompson biogas-fired boilers have been supplied to the local market in the past and these have reduced customers’ carbon emissions and reliance on fossil fuels.
