Re: HG's thread of miscelaneous stuff

The other plant for this city utility has a pair of gas turbines plus another heat recovery boiler feeding another steam turbine/generator set. This is that steam turbine set up rated at 11.5 MW.


I'd put up pics of the gas turbines but you really don't see anything but the big box enclosure its in. Sorry.

They have a smallish Unilux watertube boiler in the basement. This year it is being completely retubed, which is really rare for a watertube boiler. I don't think I've ever seen it done before. I've seen sections of tubes replaced, and individual tubes, but the only ones I've seen tore down this far were being scrapped.


Here are some of the new tubes that were recently welded in...


So that was my work day. Now how about the drive home.
