Had another boiler job the other night, though it went MUCH faster than last time now that we knew what we were doing. The guy who owned the house and called us to get the stuff out helped as well, which was really great.
Here's a quick run-down of how to break down and scrap a boiler for anyone who may stumble upon this in the future:
You'll need a sledge hammer, a cold chisel and help (this is most definitely a two-person job). That's pretty much it, save for safety equipment (gloves, goggles and N95 mask.)
The jacket going around the boiler will come off with a few whacks from the sledge and prying with the chisel (a crowbar will also work pretty well). There will be insulation which will likely have asbestos and this is why I say the respirator or mask is a necessity.
Now that you have the jacket off, you'll see that boiler itself is in sections. The one we did the other night was in four, the one before that was five. It just depends on the model I guess. Find a space between the sections that you can put your cold chisel into and start hammering with the sledge. The sections will come apart slowly but surely. There will be four steel rods, two on top, two on the bottom. You can take a whack at these with the sledge or an angle grinder will work well. Possibly bolt cutters too but I didn't try them. The rods may even break while you separate the sections depending on how old the boiler is.
Repeat with the other sections until they're all apart. Be careful when you let the sections drop/fall away from each other, as there may still be oil in the pump that is on the side of the boiler with all of the controls and attachments. Also be careful of the dust which may now just billow out. Basically it'll be like a pulverized brick material.
Wear your mask and goggles!!! I can NOT stress this enough.
Now the fun part. Haul your sections out of where they are. Likely, you'll be dealing with a basement so you may have to be creative. The middle sections are mostly hollow and they're heavy, don't get me wrong, but you can handle them with help. The outer sections, though, are beasts. They're likely going to be solid all the way through and just heavy as hell. You will probably need at least three strong people and/or some sort of contraption to get them out. If you have to go up a full flight of stairs...good luck. A very heavy duty appliance hand truck with stair-steppers with tie-downs and/or rope may be your best options.
Take it slow, breath and make sure you're hydrated! Carrying these things and working against gravity is some of the hardest work I've done in my life...and I am a firefighter!
Bring it to the scrapyard. The main sections will be short steel at most places. There is some copper and brass if you feel so inclined to break down the outer sections a bit. The oil pump thingy went in as dirty aluminum at the yard today.
Get paid, go home, take a hot shower. You earned it!
Backtracking a bit...when you're separating the sections, keep an eye out for a coil of copper similar to what you might see in a pool heater in the upper portion of the boiler. It's heavy, weighed in at 9 pounds of #2 today. The one we did a couple of weeks ago didn't have it...which was odd. So keep an eye out. You don't want ten pounds of copper going into the pile of steel!
Here's what it looks like loaded into the back of my new (to me) truck. Any questions, feel free to ask!
Once again, I didn't get any pictures of the process because it was way too dark and wet in that basement. Next time, though, I will do my best.
And here's a couple shots of the new work truck! Meet Louie!
