How nuts can I get....

PostBy: rocketjeremy On: Sat Oct 31, 2009 9:07 pm

I have kind of a random question that I'm hoping some of the coal geniuses could give me an estimate on. If I were to take say the base of a 520 with a stoker in it and instead of a boiler design a firebrick chamber and still have the proper venting, draft etc and cranked up the feed/air....could I reach say 1,800 degrees F in said chamber. Obviously this would take some time to get the brick hot and then raise the temperature in the chamber....but with rice coal and that stoker design could it be done....thanks in advance. Yes I know....crazy idea...but they are the best kind :D

You desire this to heat the branding irons for the goats? :)

I wouldn't know....maybe, but I'd bet in order to keep the flu gasses going up the chimney, you'll not get the temps that you're aiming for. What I mean is if you damper the exhaust enough to keep that much heat in the "oven", then you'll have CO leaking all over, and if you allow the exhaust to go up the chimney, the high temps will go with it. Just guessing!

Nah.....I just stare at them. I definitely see what you mean about the flue gases. This would be an outdoor setup that would go under a roof but no walls so I might not have to worry quite so much about the CO. My other thought should be to design it something like the picture below, since it's outdoors letting the gases naturally vent up and out. Not too sure about that one yet though. Not sure how toxic it would be to have the gases going through the chamber and then out.

You can push an anthracite fire up to around 4,600-4800* with enough O2 feeding it so I would say yes, it is doable. What on earth are you up to?

MWUAHAHAHAHA.....sorry....I needed an evil laugh to get me through a Monday. Glad to know that if I push it...it will in fact be plausible. I hope you understand if I don't divulge completely what I'm doing as I'm trying to corner a market on this idea but I'm trying to make a setup for something that in a sense "cures" at that kind of temperature. Just another wonderful use for anthracite!! Living in Schuykill County I've always thought it was be perfect to say that this is a "coal fired" process. You can count on a lot of pictures when I start building and updates on the results. I will also probably be looking sometime soon for a scrap "lower half" of a EFM520 to start construction.
