Stove paint inside?

I have been cleaning the inside of the EFM, and notice its rusting. Will stove paint be a good idea on the inside surfaces to stop the rust?

Thanks,

Dave

I don't recommend high temp paint for the inside. The rust on the inside will react with the sulfur in the coal gas and sort of "cure" the inside. I would make it a point to keep any moisture out. The last couple days I have been cleaning out the insides of a couple boilers getting them ready to recondition them and it seems that the ones that were painted with high temp were a bitch to get clean. The ash fused with the paint and made buildups that were a pain to remove. Any place that was "cured" brushed off easy. I would think that the bare metal would transfer heat better. When I redo one I use regular primer as it stops the rust after the sandblast and burns off quickly.

I've not a Boiler, but brushing the inside of my stoker of any rust/residue every spring seems to work good for me.

I would imagine even a high temp paint is not going to last long. At most you might want to consider painting the bottom section below the firepot and boiler section.

As long as it's operational the rust is non issue. If you have to shut it for the summer season wash it out with baking soda and water mixture, that will neutralize the acids. Open it all up and put a incandescent lightbulb in the firepot.

I got my new Keystoker 2 years ago. Cleaned the mill scale off the inside and painted it with POR manifold paint. I am dissapointed to say the least. The ash sticks to the paint like glue, and scraping the stove at the end of the season is not easy. I am welcoming the day it has all burned off. From now on it is LPS3 and a light bulb

And then the paint starts to peel and acts like a bunch of little "shelves" for flyash. No thanks, bare steel for me...keep the EFM burning or put a light bulb in it to keep corrosion at bay.

Thanks for all the replies. The boiler is in very dry basement so I suspect its the acid as Richard mentioned. I'll keep cleaning it more than once a year.

Moisture + flyash = sulfuric acid.

This is what happens to stainless steel left in a VERY humid coal stove firebox, covered in flyash. First pic is how they looked when I started getting the stove ready in the fall. Second pic is after wire wheeling all that rust & crap off them. 3rd pic is a super close-up of the cleaned surface. You can see how the acid just ate the metal away to nothing:

I just vacuum it out then put four containers of Damp Rid in it. Although this spring I did spray the Hopper with LPS3.

Please do not paint the inside of your stove!!

I did this and regret it on my koker.

The paint will peel regardless of what you use and flyash sticks to it and it's all down hill from there.

I did this 3 years ago and am glad that most of the paint has peeled off and will never paint it again.

LPS for me only!!

Thanks for all the posts. I scrapped then power brushed all the metal surfaces, lightly sprayed it with baking soda/water (interesting chemical reaction in some places), let it dry, and then sprayed with WD40 to keep it from rusting until I can figure out how to replace the burner bushing.... I'll provide pictures, but wish I had a picture before I cleaned it. I think the draft inducer creates more scale build up from the wet bagged coal. My home made dust collector with cyclone works great! I was surprised at the fine particles it collected in the bucket rather than in the bags.

Here is photo of my home made dust collector with cyclone from an old navy ship. I was clogged with something so they disposed of it in the junk yard. I cleaned it up and painted it. Also picture of inside the boiler that I am cleaning.
