3. INTRODUCTION
 All nonhazardous solid waste from a community that requires
collection and transport to a processing or disposal site is called
refuse or Municipal Solid Waste (MSW).
 Refuse disposal system
Technique for the collection, treatment, and disposal of the solid
wastes of a community. The development and operation of these
systems is often called solid waste management.

INCINERATION

7. INCINERATION
MSW is burnt in a properly designed furnace under
suitable temperature and operating conditions. This
process is called as Incineration.
The process consists of controlled burning of waste at
high temp (1200- 1500°C).
It is a process in which carbon, hydrogen and other
elements in the waste mix with oxygen in the combustion
zone and generates heat. This reaction is called as
oxidation
INCINERATION

8. INCINERATION
For complete oxidation the waste must be mixed with
appropriate volume of air. Approx. 5000kg of air is
required for each tone of solid waste burned.
INCINERATION

9. OBJECTIVES OF INCINERATION
1. Volume Reduction- To combust SW
so as to reduce their volume to
1/10th without producing offensive
gases and ash.
2. Stabilization of waste– output
from incinerator is more inert than
input due to oxidation of organic
components of waste stream.
3.Recovery of energy from waste –
Energy recovered from burning of
waste is used to generate steam for
on site electricity generation.
4.Sterilization of waste– Important for
incineration of clinical/biomedical
waste. It ensures pathogen
destruction prior to final disposal.

12. OPERATION
The operation can be divided in 6 phases:
INCINERATION
ARRIVAL OF THE REFUSALS
COMBUSTION
PRODUCTION OF THE OVERHEATED VAPOUR
PRODUCTION OF ELECTRIC ENERGY
EXTRACTION OF THE ASHES
INCINERATION
TREATMENT OF THE SMOKES

13. ARRIVAL OF THE REFUSALS
COMBUSTION
In this operation SW mix with air(oxygen).
During combustion , a tide of air will be
inserted to reach correct quantity, and
maintain high temp ranging 1000 to 1200c
.
This are SW coming from the fittings of
community selection displaced on the
territory, the refusals are preserved in an
area where the Incinerator is install with a
system of aspiration
INCINERATION

14. PRODUCTION OF THE OVERHEATED VAPOUR
The heat produced by the combustion
of methane and refusals handed to
vaporize the water in circulation is the
boiler, for the production of vapour
overheated to tall that contained
enthalpy.
PRODUCTION OF ELECTRIC ENERGY
The produced vapour is put in a movement
turbine that joined with an alternator, it turns the
thermal energy into electric energy producing
alternating current.
INCINERATION

15. EXTRACTION OF THE ASHES
The components of the non combustible
refusals are picked up in a tub full with
water posts at the valley of the last grate.
The cinders cooled in this way, are drawn
out and digest in special dumps
INCINERATION
TREATMENT OF THE SMOKES
After the combustion the warm smokes
pass in a system fine-stadium of
filtration, for the demolition of the content
of polluting agents both chemists and
solid.
After the treatment and the cooling the
smokes are released in atmosphere to
around 140°C.

16. ADVANTAGES
• The volume and weight of the waste are reduced to a
fraction of its original size.
• Waste reduction is immediate, does not require long term
residence.
• By using heat recovery techniques the cost of operation
can often be reduced
• By using this waste easily converted in to usual form of
energy.
• And the extracted fly ash is recycled and also used
for filling agent.

17. DISADVANTAGES
 The capital cost is high.
 Skilled operators are required.
 Not all waste can be burned
 Incineration plants involves the heavy investment & operating
cost.

18. CONCLUSIONS
However, with the growing problems of waste
management in the urban areas and the increasing
awareness about the ill effects of the existing waste
management practices on the public heath, the urgent need
for improving the overall waste management system and
adoption of advanced, scientific methods of waste disposal,
including incineration is imperative.
