Figure 4-17. Inclined plane incinerator.
(2) Simplified inclined plane incinerator. If time does not permit the
construction of the inclined plane incinerator as illustrated in figure 4-17, a simplified
version can be constructed. Dig a fire pit at the bottom of an incline, line it with rocks,
and place a grate over it. Place three telescoped drums in a shallow trench up the
incline. Let the lower end of the telescoped drums extend somewhat over the fire pit so
the flame will be drawn up into the drums. If a sheet metal plane is available, it should
be inserted inside the drums since it helps the garbage to dry more thoroughly before
(3) Barrel incinerator. A barrel incinerator (figure 4-18) is made from a
55-gallon drum by cutting out both ends, punching many holes in the side near the
bottom of the drum, and inserting grates inside the barrel several inches above the
holes. The barrel is placed on stones, bricks, or dirt-filled cans so that the bottom of the
barrel is several inches above the ground and air can get to the bottom of the barrel
easily. A fire is then built in the space under the garbage barrel. Garbage is put onto
the top grate of the barrel and incinerated by the heat from the fire.
