… network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may …
… of a long term silvicultural suggestion to bring about more stable border zones most close to the railway, without silviculture of too high intense and expense.On the 14-kilometre section between Emmaboda and the border of Blekinge County, 30 percents of the forest consisted of …
