Sokratherm GG 198 D Gas CHP
The brewery intended to reduce its energy cost and CO2 emissions by producing electricity, steam and heat directly on site. Before the installation of the CHP/steam generator plant, all electricity had been drawn from the mains and all heat had been produced by two large steam boilers.
Sokratherm installed a turbocharged CHP unit of the 200kW-class, a steam generator, bypass, condensing heat exchanger and mixture cooler in one heat station. Since the (non-steam) heat is used to raise the brewing water temperature from 15 to 85 degrees all heat sources can be used and the total efficiency achieves 94.1%. All electricity produced by the CHP unit is used on site because the scheme only runs when beer is brewed.
