How to modify the alcohol stove?
In use, the firepower is not strong enough, which wastes alcohol. If the alcohol stove is slightly modified, the above shortcomings can be overcome.
First, use a small stainless steel teacup with a diameter of 5070 mm (light weight, not easy to deform, just cover it with a lid when it is closed, and it is easy to move with a handle) as the furnace body. At about 58 mm below the rim of the cup, evenly drill a row of small holes with a diameter of 0.20.5 mm, with a distance of about 5 mm (not too big, the flame will be too high if it is too big), and use a slightly hard iron nail to penetrate it (see figure 1).
Then cut and flatten the aluminum can, and cut it into rectangular aluminum pieces with a width of more than 5 mm and a length of about 5 mm greater than the outer circumference of the cup (two pieces can be spliced if it is not long enough). On both sides of the width of the aluminum plate, one end is cut into a corrugated shape, and the other end is cut into a 44 mm strip (Figure 2a). Then roll it down into a cylinder (see figure 2b) and put it into a teacup, and fix it by folding the upper edge (pay attention to the direction, there should be a gap between the lead skin and the cup wall). At this point, the simple alcohol stove was made (see Figure 2c).
In the improved alcohol stove, alcohol is directly poured into the teacup, and the flame burns in the cup first; When the alcohol temperature rises, the alcohol vapor rises along the gap between the inner and outer walls (the cylindrical aluminum skin doubles, naturally forming a gap of about 0.5 mm with the cup wall), and overflows from the small hole of the teacup to ignite, forming a multi-head small flame with strong firepower, strong wind resistance and more energy saving (see Figure 3).
It should be noted that when igniting the alcohol in the furnace body, do not ignite it directly with a lighter, which is easy to burn your hands. It is more appropriate to dip the rolled straw or paper in alcohol, and then ignite the alcohol in the furnace after ignition.
