Mid-season cleaning

Mid-season cleaning

PostBy: Rob R. On: Sun Dec 29, 2013 3:58 pm

I decided to take advantage of the warm weather and give my 520 a quick brush down. I have never seen anything like this since owning it. There was a light crust of flyash on the surfaces that I couldn't totally get off when I cleaned it in September. Apparently it is peeling off and collecting a lot of fly ash. Almost looks like paint peeling, but it isn't. Usually it just has a fluffy layer of flyash that is easy to brush off...this stuff required some elbow grease.

My only theory is that running the boiler at 140 degrees all summer allowed some flyash to "stick" to the metal surfaces and now that the boiler is working hard, it is peeling off. Regardless, it took me 20 minutes to clean it and I am glad that it is done.

For those that have never done it, you can put a few scoops of ash on the fire and pull the baffles out with a pair of welding gloves...do your cleaning and restart it without losing the fire.

Rob, good tip on the ashes. I did the same thing today with my Pocono. 42 degrees outside, but I shut down the combustion fan to do my cleaning. I was smelling a bit of coal gas yesterday with the outside temp up. Fire was just at idle so there was not much draft.

Now that I've cleaned everything, I had a full stoker pan fire for the last hour. I've never had it last this long before, so I'm just letting settle down. Pretty hot fire. Keeping an eye on it.

Great minds think alike! I decided to take advantage of the warmer temperatures and clean the EFM today as well. I started by removing and refilling the oil tray, then I realized the "dogbone" was on backwards, the lower oil port was facing the blower housing. Checked the gearbox next, then gave the boiler a cleaning. I just shut off the power, never lost the fire either. I found about 4 inches of fly ash in the chamber in the base, then brushed out the 10 tubes. It was time. Also vacuumed all the fly ash out of the breech.
And you plate boiler guys think you have all the fun! :D

Looks like the fly ash is mounded right over the tubes!

What happens is the ash collects in the cleanout opening, beyond the ash "wall" are the tubes. I have the vacuum handy when I remove the plate for the handful of ash that falls out.
