Questions to power supply systems in Aalborg area

[Obelixx]

I have got some questions about some electricity supply systems in Aalborg area:

Nordjyllandsvaerket has 4 chimneys, but according http://www.vattenfall.dk/da/file/nor...dk_7841587.pdf
it has only 2 working units and 1 gas turbine. Why are there 4 chimnies? Does the gas turbine use also one of the three
larger chimnies of Nordjyllandsvaerket or does it use a small chimney covered by the buildings of the power plant? ( I know from a similiar facility in Germany, where the gas turbine unit uses a chimney, which is little in comparision to the huge chimney of the coal-fired unit).

Close to Nordjyllandsvaerket, 2 powerlines crosses Limfjorden overhead. The eastermost of these lines
has the tallest electricity pylons in Denmark. Has someone pictures of them?

A bit eastward in Vester Hassing, there is one of the oldest HVDC stations in the world, the startpoint
of "Konti-Skan". In 2007 the old mercury arc valves of Konti-Skan 1 were replaced by modern thyristors. Were some
of the old valves donated to museums? If yes, to which museums?

I was in Ålborg today, on a bussiness trip and took this snapshot for you, of the eastern most HV pylon. As I see it, the pylon is close to same hight, as the highest of the chimneys. Not the best PQ, hope you can use it.:
