Nope. It's natural gas. See the pancake looking thing behind that pipe in the middle of the picture? That's a gas regulator, followed by what looks like (And according to code, should be) A hydraulically assisted automatic shutoff valve. It may have been converted from coal... Just looking at the form and the fact the pipes are much newer than the boiler support structure.

well i wouldn't doubt anything you say really XD cause i don't know shit about a boiler i've seen a few coal boilers and over sized scale oil boilers but thats about as far as my knowlage goes

Hehe. I'm actually an electrical engineer, but I've been in SO many jobs, and I have an insatiable thirst for knowledge.. To the point that I can tell you, on the side of that hydraulic valve, if you look, you'll find a lever, that's probably connected to a spring trip (Though it may not be conntected to anything, depends on how old the boiler is... But the lever will be there..) Let's just say that I know that valve, rather intimately. I used one to make a safety shutoff on a massive compression tank. Heh.

you'd love half the stuff on the carnival we work at the main large hydrolics XD

I used to write code for an old Cincinatti Milacron T-3 robotic arm. Man that thing was fun to play with.. We used to use it to do TOTALLY stupid things when we got bored.. Like one day we had it just pick up pipe, and then dance around with it for about twenty seconds in the middle of the index loop, but I made it a random action based on the size of the pipe.. So it wouldn't always do it, but then it would randomly start busting out moves when it would get a certain diameter pipe in it's gripper. Heh. Those were the days.. But that thing could MOVE too. Heh. Nothing quite like whipping a thousand pounds of metal around at 50 inches a second at the point of axis, to which you combine the eight to fourteen feet of arm as a lever from the point of axis, and the linear speed is MUCH greater. Heh.. Man.. Memories..

This place looks wicked to explore. :P

Where did you find your little ghost building? I'm suprised it isn't covered in graffiti. Makes it that much the more eerie.

this remind me of the cloack tower room in "house on haunted hill"

ah machinery has that effect :3

x.x i didnt think those rooms could get more creepy
