I love Google’s image search. This is one of the main sources for new Sankey diagrams on this blog.

The other day I used the Czech term for cogeneration (‘kogenerace’) … and immediately had five new diagrams to share with you. Two of them can be found below…

As in most cogeneration schema diagrams, two energy production systems are compared in one diagram. The classic one, and the combined heat and power CHP system. Heat (teplo) and electricity (elektrina) output is set to the same size and primary energy requirement is being compared. Losses (ztráty) branch out to the other side. In the first one these two systems (found on the EkoWATT website) are shown in a vertical orientation:

The second one (from All for Power website) has a horizontal orientation:

The cogeneration system is 1.4 times more efficient (140:100) in the first diagam, the second Sankey diagram has cogeneration 1.47 times more efficient (100:68).

Two or three more to come in another post next time.
