Some solid fuel furnace designs I have seen incorporate a "Dump Flap" that allows you to drop the coals out of the cold furnace. (In paricular cupola designs). Otherwise you have to turn it upside down to empty it out! --- End quote --- I have a dump gate at the bottom of the cupola I built, but the smaller aluminum charcoal melters get dumped by hand. Usually at the end of a pour, I cover the exhaust port and tuyere with a brick. This extinguishes the charcoal, saving quite a lot of it for starting the next time. It also slows the cooling of the furnace interior, so reduces cracking. I also leave the hot but empty crucible in there for the same reason. It's easier on crucibles (I believe.......warning, personal opinion!) |

VT Steam Completely O/T here, but I really like your dog! Looks remarkably like my late and still lamented friend Max who enlivened my life for 16 1/2 years. Give him/her a milk-bone on my behalf! Joe |

Certainly will, Joe. He's a long legged dachshund. Half border collie, half long hair dachshund. I don't know which half is which, though. |
