Method
This incinerator serves a teinparary purpose in a dispensary or health centre If the health structure becomes

Cut the top cleanly off a 2001 metal dnsm, around 2/3 ofits perimeter (tee fig 1) Cut a hole the dsameter of
the chimney in theremaining part of the cover
- Perforate a metal plate (length = internal height of drwn, width • diameter of drum at the place the cover
was cut), all over its surface with holes about 1-2cm diameter Slide it into the drum and fix it so as to
divide theinside into two chambersofunequal volume.

- Cut some rigid metal grating, or make some with the same avis section as the large chamber of the drum
(m front ofthe metal plate), and fix it horizontally about 20cm from the bottomof the drum
— Cut out a panel 40 x 40cm at the bottom of the drumand remount it as a door using hinges.
— Fit a chimney (about 2m high) on the hole made In the fixed part of the cover.

Operation
Fill with refuse from the top.
— Fifi thebottom with firewood through the door (6)
— Light the fire and give It time to take well.
- Monitor the combustion, turning over the refuse frequentljc

Important
Never over-fill with refuse. as the draught comes from the fire, the pile of refuse shouid not be too
compact
—Donot empty the incinerator from the top, only take out theashes whsch fall.
- Clean out the fire chamber frequently
—Donot try toeconomlse on firewood always keep a good fire going to guarantee complete combustion.
— Turn overthe refuse frequentlyduring combustion tomake the ashes fall and to expose all therefuse to the
flames
- Never put exploalve objects (e g. aerosol cans) in themclneratoi or matenals which give off toxic fumes on
combustion (certain medsones for example) Always seekadvice before in case of doubt.
— Situate the mdnerator where the smoke will not bother people, and place it under a shelter if possible to
avoidcorrosion being worsened by rain.
- The door (6) may be adjustedto regulate the draught However if the draught Is enough, indneratlon with
the door dosed Is the most economicalon firewood.
- If it Is used frequently, such an incinerator will not last more than a few months (less than a year because of
corrosion due tothe great heat generated).
