Dear Coal Crazy, I have an ashley 1602R. I'm having ahard time with it. When I read the manual, it said nut, not stove. So I'm using nut. I'm also not sure how much to pile on at night. and i'm not getting nearly the amount of heat i get when I burn wood in it. What am i doing wrong ?
When you put coal in it don't be afraid to fill it up to the top of the fire bricks and yes I know that's a lot of coal but if you don't you won't get the heat your looking for. You will need to add the coal slowly. Put a layer in and let it catch before you add more.
I just added A barometric damper to my coal stove and it is a must have in my opinion my next question is where to set the ash pan damper? I noticed the draft goes up a bit wen I give it more air.......even with a baro (the baro is maxed, so that may be why)
I noticed that my combustion analyzer does have a setting for coal. Has anyone tried this if anyone is familiar with the correct numbers I should have for oxy and co, is there any other values I should check? please feel free to chime in I would love to respark this topic thanks joe
Anyone know what acceptable levels of co in the flue gas are? Any way to know how much efficiency is wasted by leaving it run that way? If I give it more draft I'll roast my self out...... Even once it gets cold out
CO is unburned gas in coal stoves and coal stoves are notorious for CO production which happens when a stove is damped down or when the air distribution through the coal bed is uneven. A round insulated fire pot is best for air distribution and maintaining the high heat necessary to burn the gas. A good fire will have blue flames all the time, not just when initial volatiles are released. CO occurs all the time because air distribution is never perfect and some parts of the fire starve for air and that blue flame is CO burning in a mature fire.
Stokers burn smaller amounts with a steady feed so have less of a problem consuming CO just as wood pellet stoves have an easier time burning without smoke.
No matter what the fuel, to burn efficiently means mixing the air evenly and maintaining the heat necessary for good combustion. There is no acceptable figure, there are just degrees of unacceptability as stove are operated over such wide outputs. Because it does not smoke it is accepted but combustion efficiency will vary just as much as varying output, just like wood.
