Abstract
Incineration is the combustion of waste materials at a high temperature
environment. It functions as an alternative to landfill and biological
treatment methods such as composting process and anaerobic
digestion. This work developed a household incinerator for combustion
of municipal solid waste. The incinerator consists of a square mild steel
box 340 mm x 340 mm, gas burner, grate exhaust and a temperature
indicator. The components were designed according to standard
engineering procedures and materials selection was based on
functionality, durability, cost and local availability with the maximum
loading capacity of 2.0 kg of waste. The incinerator was assembled by
lining the inner wall of the incinerator with fibre glass of 2 mm
thickness after which the temperature indicator was positioned. A
rectangular hole of 80 mm x 70 mm was cut from the exhaust at the
upper part of the incinerator and rectangular hole of 200 mm x 100
mm was also cut at lower part of two adjacent sides to allow air in the
combustion chamber. The developed incinerator was tested using gas
as a source of heat. The quantity of heat required for combustion using
the developed incinerator for waste paper and plastic were; paper and
plastic (combined) 1630.0 kJ, paper1571.14 kJ, and plastic 940.21 kJ.
The maximum paper capacity for the incinerator was found to be 2 kg
with a burning time of 17 to 18 minutes while that of plastic was 1 kg
and the burning time ranged from 20 to 30 minutes. For combination
of plastic and paper, it was 1.5 kg and burning time ranged from 17 to
30 minutes. Ash was prevented and kept for further engineering use. In
a densely populated area, where finding space for additional landfill
was difficult, incinerator made it easier. The developed incinerator was
capable of performing the expected function though it is recommended
for incineration of low volume of wastes.
