Jared43758 wrote:When I burn wood I leave quite a bed of ashes because it seems like it holds more heat. When I'm burning coal I try and remove all ashes right? So the coal is right down by the shaker grate and grate is clear to let air through? Then try to not melt or warp my grate?
The grate on these units have a lot of solid surface area so it keeps some ash on its top side unintentionally anyways. As long as the ash pan is kept empty so primary combustion air can get thru without restriction, there shouldn't be an issue with over heating the grates.davidmcbeth3 wrote:Remember, the ash acts as an insulator for your grates .. so a little is good.
I use 5-6 tons for 2400 sq ft house per year and range 30-80 pounds per day depending on how cold it is.. (30 pounds per day during mild spring and fall days, 80 pounds per day during below zero cold winter days). The general rule is 1 ton per 500 sq ft per year, but that's just a rough calculation. For bit coal, the big chunks are better, like tennis ball - softball size pieces.Jared43758 wrote:How much coal roughly should I use a day? How many ton range a year? Best sizing to use?
I agree this is a better view point.. Good thinking!carlherrnstein wrote:Here is a example of my thinking these numbers are just to show a point. If you burn 100lbs of wood per day to keep your house 70*F and get 1.5lbs of ash. If you were burning coal might burn 60lbs of coal to keep your house at 70*F and get 6.6lbs of ash. There is more ash in coal however there is also more heat.
I wouldn't try to burn soccer ball size chunks. Softball to grapefruit size should be plenty big enough. Keep the sizes uniform. Nut size bit coal will melt and fuse together forming a big solid mass that needs to be broken up later in the burn to keep heat output good..Jared43758 wrote: Great big peices of coal won't hurt? Still burn hot?
