(2) the lid: the barrel lid all cut off or separated in half, for adding sawdust; the lid should be sealed to prevent leakage of smoke, you can use the soil to bury; the top of the lid can also be designed to fill the pipe; the filler pipe on the open leakage holes, the hole should be on the top, the hole should be on the bottom, the hole should be on the bottom. The density or size of the holes should be big on top and small on the bottom.
(3) chimney: welded in the lid or the barrel above the chimney, smoke extraction vertical or flat; chimney can be designed to regulate the temperature of the insert, but must prevent leakage of smoke, preferably in the design of the chimney part of the outstretched warming room; such as the stove burns too fast can be plugged on the chimney end with a can, etc.;
(4) ignition holes / ventilator holes: in the middle of the bottom of the barrel (center of the circle) to play a 20-30 cm diameter ignition hole 20-30 cm ignition hole a, the first hole to play a little smaller, try to see the effect of the stove; if the temperature is not up, and then expand the hole or in the big hole around the appropriate opening of a few small ventilation holes; do not one-time ignition hole is too large, or directly hit the ventilation holes, if the bottom of the closure is not tight, the temperature is easy to be too high.
Mesh iron tray: add a mesh iron tray with height higher than the top edge of the vent hole on the inside of the oil drum, and load sawdust on it.
Furnace door: at the bottom of the barrel with iron plate welded into a box about 20 centimeters high, or brick, for ignition and play the dampers about, but to be able to seal.
(5) loading furnace: when adding sawdust, you can spray water appropriately, so that the sawdust has the right humidity; the general requirement is from bottom to top from dry to wet, but the specific degree of dryness and wetness, according to the individual stove, use for a period of time in order to figure out the law; before loading the sawdust, with a stick upright in the center of the fire ignition holes; loading the sawdust to pay attention to the smoke and soot; fill the sawdust with a thick stick pounding the sawdust; don't put the The whole stove is filled, leaving a space of one to twenty centimeters high on top; when drawing out the stick, it should be compacted by shaking it in all directions to prevent the sawdust from collapsing, and a hole should be formed in the center after drawing out the stick to make it easier to light the fire.
(6) Ignition: after the sawdust is loaded, the ignition hole at the bottom is used to start the fire with flammable firewood; the ignition can be assisted by a fan or a blower;
(7) Temperature control: the temperature can be adjusted through the dampers, the temperature-regulating inserts on the chimney, or through the water-filled pipe with water; this kind of stove is large, loaded with a lot of material, and once the stove is on fire, it will dissipate the heat very quickly, and the sealing is not tight, and the high temperature is very easy to be reached. When high temperature scorpion room can first spray water to improve humidity, can play a cooling effect. Or open the doors and windows, ventilation and cooling.
(8) safety: after the fire barrel temperature is very high, do not touch with your hands; winter in the scorpion room work, to prevent the clothes, especially the down jacket, etc. touch the stove; chimney temperature is also very high, if the chimney is very bottom, hair do not touch the chimney; stove fire, do not open the lid to prevent the fire flames out of the fire; smoke and oil to let the flow out of the smoke or smoke pumping the lowest place to play a hole; when the wind is blowing, but also to prevent the smoke from chimney The chimney should be kept free of smoke and oil, and the chimney should be kept free of wind.
