Abstract
The disposal of waste has always presented significant practical
and human problems. In many countries waste disposal has been biased
essentially towards dumping and landfill. By introducing incineration
plant into the waste disposable system not only will the volume of
refuse be considerably reduced, but also its residues will be
sterilized. In addition thermal and electrical energy can also be
obtained from the plant. The necessity of introducing incinerator units
into the waste disposal system is important because almost 60 percent of
household waste matter is organic material with a substantial energy
content. According to investigations carried out by the author, each
person generates about 1 kilogram of garbage each day in Australia. In a
city with a population of four million people, about 4000 tons of
garbage is produced every day. This could be burnt to generate 2.4
million kilowatt hours of electricity per day at a continuous rate of
100 MW. Using garbage as fuel in power stations would help energy and
waste disposal problems. This paper discusses the current waste to
energy technology and the problems associated with this technology, as
well as advantages of introducing incinerators into the waste disposal
system in Australia, daily household waste which is produced every day
in different cities of Australia, energy contents of the household waste
matters, possibility of establishing incineration plant for waste
disposal, energy recovery function and description of major equipment
used in incineration plants
