How to Keep Glass Clean On Coal Stoker

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I have a Reading Allegheny stove and when I bought it used, the glass was covered with deposits and you really couldn't see through it so I bought a new one. I am looking for a way to keep it clean when I use the stove or any stoker for that matter. My Russo hand fired stove had etched glass when I bought it and it hasn't gotten any worse since burning 20 tons through it. it stays clean for the most part.

Step away from the glass :x I was that guy that was not going to have that happen, I lost the clean glass just like everyone else. I had a Buderus hand fed for 27 years, when I sold it the glass was polished one last time and almost crystal clear. On a stoker it is a lost cause.

Here's an idea, is there any way you could mount a "disposable" cheaper piece of glass inside to protect the original glass?

I will be following this one closely. I have a Keystoker 105 that I tried keeping clean. Even got the piece of sheet metal to put in the door opening while you wait for the glass to cool down. I've tried everything and can't get rid of it. I've given up for the year unless someone has a way to do it. I'd love to be able to see the actual fire and not just the orange glow.

Just welcome the orange glow with open arms!!
I know, 10 years ago I fought the glass battle. The sooner you accept the orange glow the better life will be.
And ya know what? I still have that same glass that I bought 10 years ago. The acceptance of the orange glow is easier on your wallet.
Take Care and God Bless

both my stoves came with a cover when you open the door, to cover the opening., let the door/glass cool down, and use the Rutland Stove Glass cleaner, you probably have to do it everyday to keep it nice. I gave up a long time ago trying to keep it clean. I do clean about once a month or more, or when I have to start the stove to match sure it lights properly.

I do notice my Keystoker with the special air tubes to wash the glass inside the stove, it helps some to keep it a bit cleaner longer, but still gets covered in ash and stuff.

I've been lucky with this one so far. Every few days I scrap it with a razor blade. It still cleans up pretty good. It's been in use since January 2nd 2016.

I don't know if it being a boiler has anything to do with it. Maybe it does?

There are few problems in life that cannot be solved by lighting something on fire.

What is that coating and why does it happen ? It seems that its some sort of crystalline structure the way it grows.....has todo something with boundary energies maybe on the glass as well but not exactly sure......Maybe a good PhD project that Trump can fund. :D
