primitive technology: natural draft furnace
Bookmarked 436 weeks ago i built a natural draft furnace to test ideas about how hot a furnace could get without the use of bellows natural draft is the flow of air through a furnace due to rising hot air the hot gasses in the fuel bed are more buoyant than the cold air outside the furnace causing them to rise fresh combustion air then enters the base of the furnace to replace the rising combustion gasses keeping the fuel bed burning this effect increases with: 1 the average temperature of the fuel bed relative to the outside air and 2 the height of the furnace two other important factors are the size of the tuyere air entry pipe and lump size of the fuel bed as these effect the resistance to airflow through the furnace the furnace was tested with wood fuel and some ore was melted but produced no iron high temperature were indeed produced probably about 1200 c these types of furnaces were once used for smelting copper and iron ores in around the world in ancient times usually using charcoal as a fuel and in some cases |

primitive technology: blower and charcoal
Bookmarked 407 weeks ago i made a blower and some charcoal at the new area in order to create higher temperatures in for advancing my material technology i took fan palm leaves and fashioned them into an impellor about 25 cm in diameter held in a split stick as a rotor i then built a housing from clay slightly more than 25 cm diameter with inlet and outlet openings about 8cm in diameter and assembled the blower i opted not to make a bow or cord mechanism as ive done before due to the complexity and lower portability of such a device the lighter impellor material leaf instead of the previous bark made it easier to spin by hand anyway as it has a lower momentum each stroke of the spindle with the hand produces 4 rotations so about 2 strokes per second gives 480 rpm the blower increases the heat of a fire when blowing into it and i would guess its more effective than a blow pipe and lungs but dont how it would compare to a primitive pot or bag bellows for air supply a small furnace was made and then fired with woo |
