3. INCINERATOR : Types, Specifications and Time Cycles of Bio-Medical Waste
Incinerators
Incineration is a waste treatment process that involves the combustion of organic substances
contained in waste materials. Incineration of waste materials converts the waste into ash, flue gas, and heat.
The ash is mostly formed by the inorganic constituents of the waste, and may take the form of solid lumps or
particulates carried by the flue gas. Incineration has particularly strong benefits for the treatment of certain
waste types in niche areas such as clinical wastes and bio medical wastes and certain hazardous wastes
where pathogens and toxins can be destroyed by high temperatures.
The following are types of incinerators:
ROTARY KILN
FLUIDIZED BED
LIQUID INJECTION
MULTIPLE HEARTH
CATALYTIC COMBUSTION
WASTE-GAS FLARE
DIRECT-FLAME
ROTARY KILN INCINERATORS SPECIFICATIONS:
Rotate wastes in rotary kiln, enabling thorough mixing with air
Operating temperature from 800 - 1400 degree Celcius
Has great resistance to high temperatures
Can handle liquid, sludge, solid, gas in large quantities
Can handle batch modes like barrels and allows more flexibility than continious modes
Can operate in batch mode, allowing more flexibility than continuous mode.
Capacity of Medical waste estimated at 24 MJ/kg (5735 kCal/kg)
Inside Diameter : 1.65/1.4 -3.0 cms
Rotary Speed : 0.52 1.55 r/min
Power Equiped : 15 – 55 kw
FLUIDIZED BED INCINERATORS SPECIFICATIONS:
vessel contains inert granular material that expands and acts theoretically as a fluid when gases are
injected up through the material bed from nozzles
Operating temperature from 1400-1800 ° F ( 750 -1000 ° C )
Compared with the bubbling fluidized bed with air speed of lm/sec, the CFB has an air speed of 4-6
m/sec.
The required static pressure of the fluidizing (combustion air) blower is low, consuming less power.
The bubbling fluidized bed needs 25-30kPa compared to 15-25kPa of circulating type.
The medium intensifies contact, mixing and blending of air, waste and heat, raising the combustion
efficiency and enabling low air ratio combustion.
It is easy to adjust the amount of circulating particles by controlling the primary air. Local
temperature drop or surge can be prevented.
4. The heat carried back by the circulating particles helps dry the sludge, preventing temperature drop
in the lower part of the furnace, requiring no auxiliary fuel.
LIQUID INJECTION INCINERATORS SPECIFICATIONS:
Wastes are sent through nozzles and atomized into small droplets to allow for the greatest possible
mixing with air.
Operating temperature from 1200-3000 F.
Feed must act as a liquid having a viscosity less than 10,000SSU
Solids entered should be melted and pumped.
Can completely combust non combustibles like contaminated water, along with organic combustible
material.
Has horizontal or vertical configuration.
MULTIPLE HEARTH INCINERATOR SPECIFICATIONS:
consist of vertically shaped hearths, and are Primarily used for sewage sludge.
operated from 1400-1800 ° F ( 750 - 1000 ° C ).
Catalytic combustion, waste-gas flare and direct flame incinerators are all for gases.
Catalytic combustors use a catalyst and are designed for low organic concentration wastes.
Waste-gas flares are used for non-hazardous waste that has high organic content.
Direct flame incinerators operate from 1000-1500 f and are used when waste gas contains particles.
The ideal wastes for this kind of disposal are toxic and hazardous wastes such as chlorinated matter,
pcb's,and organometallics
COMBUSTION INCINERATORS-OXYGEN USING SYSTEMS SPECIFICATIONS:
Waste and storage handling
Waste feeding

COMBUSTION STAGES
Drying moisture is evaporated.
Devolatilization – combustible volatiles are released.
Ignitions – volatiles are ignited in the presence of o2
Combustion of fixed carbon volatile matter is completely combusted and fixed carbon is
oxidised to co2
5. TYPES OF COMBUSTION INCINERATORS
MASS BURN-MOST COMMON
o WATER WALL FURNACE
o REFRACTORY FURNACE
o ROTARY KILN FURNACE
FLUIDIZED BED COMBUSTOR
NON-COMBUSTION TECHNIQUES-OXYGEN DEFICIENT INCINERATOR SPECIFICATIONS:
BIOGASIFICATION
Mixed solid waste is placed into an anaerobic digestor to reduce its Volume and to
produce methane. The process involves:
preprocessing-the organic material is separated from the waste stream, shredded, and
placed into a slurry
decomposition-the slurry is placed in an anerobic digestor for 5-30 days
gas collection-methane gas is collected and refined for combustion
less voluminous digested product for disposal
PYROLYSIS
Uses heat to decompose the mixed solid waste in an O2-deficit or O2-free
Environment. The products of pyrolysis include combustible gases and Various solids that
are difficult to manage.
MUNICIPAL INCINERATORS SPECIFICATIONS:
More common
Less consistent waste stream
Pre treatment like shredding, drying is usually necessary
Batch or continuously loaded.
CONCLUSION:
Any solid, fluid and liquid or liquid waste, including it's container and any intermediate product,
which is generated during the diagnosis, treatment or immunisation of human being or animals, in research
pertaining thereto, or in the production or testing of biological and the animal waste from slaughter houses
or any other similar establishment. All biomedical waste are hazardous. In hospital it comprises of 15% of
total hospital waste. As quite a large percentage of waste, generated in Indian hospitals, belong to bio
medical category (non-toxic and non-hazardous), hospital should have constant interaction with municipal
authorities so that this category of waste is regularly taken out of the hospital premises for land fill or other
treatment like incineration which involves The process of burning a material so that only ashes remain.
