Maximizing Efficiency of Your Hand Fed Appliance

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Yeah man, the vertical sides of the firebox get coated with fly ash. I'm betting its because the sides are cooled by the blowers quite drastically, since mine is a hand fed furnace as opposed to a hand fed stove. The sides of a stove's firebox probably stay much hotter I'm willing to say. This may be the difference.

Another tweak of efficiency 8-)

Recently, I've been watching my baro to get an idea of what the gases off the top off the coal bed are doing. I've noticed that with more secondary air over the fire, the gases burn more stable and the baro will be stable.. With less secondary air over the fire, the gases will flash slowly, with combustion all at once as the right air mixture is achieved with the slower incoming available oxygen. I call these mini-puffs :lol:

What I'll do is adjust my secondary air so the mini-puffs can't become mega-puffs hahaha.. At that point, I'm letting in enough oxygen to keep a major puff back from occurring, but at the same time its not too much that I'm allowing an excessive amount of heat up the chimney :D

I was watching mine this morning set at .03 and going to .05,then I held the baro closed and it went to 1.5 and 2 with the high winds were having,that just shows how the baro is actually saving your heat and helping the effciency also
