Managed to translate most from a website on process heat from solar systems installed in a brewery I had found recently. (again a Sankey diagram from a brewery!). The article sports four different Sankey diagrams for the energy flows in the brewery: one for the entire calendar year 2010, and three further ones for January (winter mode), March (transition period) and July (summer mode) of the same year. This work at Hofmühlbrauerei Eichstätt brewery was apparently supported by Technical University of Chemnitz.



Energy is obtained from three different solar collector fields with different harvest. Flows are in kWh. Energy harvest in March was 75.158 kWh, and in July went up to 132.155 kWh. A description of the whole system and photos can be seen on this page (text in German only).

There are three consumers (the three pink boxes at the right)) that each have different demands depending on the season: Indoor heating (“Raumheizung”), brewing water and domestic water pre-heating (“Brau- und Brauchwasservorwärmung” – Google Translate didn’t help me on this one…) and warm water for the bottle washing machine (“Flaschenwaschmaschine”).

While in winter most of the energy from the solar collector system is directed to indoor heating, in summer it is the opposite: since no indoor heating is needed the whole energy harvest can go to water heating for the other machines. The storage tanks also have a color scheme indicating the temperature.

Very nice! Good work!

A company brochure commemorating ’10 Years of Environmental Management’ at Murau Breweryin Austria features this sparkling green Sankey diagram:

The diagram visualizes gaseous emissions (carbon monoxide, carbon dioxide, oxygen, nitrogen, …) from different equipments (e.g. steam boiler, fermentation tank, flare, …) in 2004. Carbon dioxide emissions are given in absolute values as flow label. All flows in kilograms (Note: nitrogen quantity (‘Stickstoff’) probably erronously labeled ‘Mio kg’ in the legend).

Good job … Prost!
