The document describes a biomedical waste incinerator designed for disposal of hazardous medical waste. It has two chambers - a primary chamber that burns waste at 800°C and a secondary chamber that ensures complete combustion at 1050°C. The incinerator meets all regulatory standards with 99% combustion efficiency and less than 0.01% volatile organic compounds in ash. It is available in sizes that can burn 20-200kg/hr of waste and features automatic controls and safety devices.

1. Biomedical Waste Incinerators
A PRESENTATION

2. Applications:1
• The GK incinerator is designed specifically for the disposal
of Type 4 waste with 85% moisture and is used extensively in
• Hospitals, Nursing Homes, Clinics, Veterinary Institutions,
Research and Industrial Laboratories for the disposal of
human anatomical waste including human tissues, organs,
body parts, carcasses, bleeding parts, fluids, blood and
experimental animals used in research; Microbiology and
Biotechnology wastes from laboratory cultures, stocks and
specimens of micro-organisms, live or attenuated vaccines,
human and animal cell cultures, infectious agents, wastes
from production of biological, toxins, dishes and devices used
for transfer of cultures; Solid wastes including items
contaminated with blood and body fluids, cotton, dressings,
soiled plaster casts, linen, bedding and other material.

3. Applications:2
• Biological and Pharmaceutical Research Labs for the
disposal of tissue and plant culture, animal cadavers
and outdated drugs.
• Municipal Corporations for the disposal of civic waste
such as garbage.
• Port Trusts and Road Transport Corporations for the
disposal of garbage and canteen waste.
• Canteens, Hotels and Wedding Halls for the disposal
of vegetable and food waste.
• Poultry Farms, Hatcheries, Zoological Parks and
Animal Houses for the disposal of eggs, dead chicks,
carcasses, etc.
• Available in capacities from - 20 kg / hr. to 200 kg / hr.

4. Design Features of the
Incinerators:
• Horizontal Design - Primary and secondary chambers housed
in single shell
• Destruction efficiency 99.00%
• Handles Type 4 waste with 85% moisture content
• Special high alumina low cement cast able refractory
providing for high cold crushing strength
• Operates on 220-240 V single phase 50 Hz AC supply
(except models GK 18, GK 25 & GK 35 which require 440 V
three phase supply)
• Extended residence time of >= 1.0 sec
• Separate small ash doors
• Meets CPCB norms with no downstream equipment
• Long equipment life

5. Burner:
• Single pressure jet oil fired mono block
burner for primary and secondary burning,
meeting temperature requirements of
800°C ± 50°C in primary chamber and
1050°C ± 50°C in secondary chamber
• Fuel efficient, with return pipe for saving
excess fuel

6. Construction Details &
Additional Features:
• Automatic electronic sequence monitoring device
mounted on control panel for safety and long life
• Protective thermo well for long thermocouple life
• SS braided seals for all doors
• Coated SS anchors for excellent bonding of refractory
to shell
• Low skin temperature due to cold face protection
• Unique surface preparation for painting
• High heat and corrosion resistant paint
• Very low running costs
• Low electric power requirement (Max. 0.75 KW)
• Negative pressure for operational safety
• Free operator training at site

7. Ingenious Design
• The design concept of this incinerator enables the
use of only one burner in place of two, thereby
enabling high cost savings. The incinerator
contains two chambers housed in the same shell.
Waste that is loaded in the primary chamber is
burnt and the products of combustion flow across
the hearth, into a secondary after-burn chamber.
The flue gases pass through the core of the burner
flame and travel across the primary chamber for
recirculation providing for extended dwell time
before emission, thereby enabling complete
destruction of suspended carbon particulates,
smoke, fumes and odour.

8. Norms Followed:
• As per the notification of the Ministry of Environmental
and Forests dated 20th July 1998, regarding
standards for incinerators, our equipment satisfies the
requirements as follows:
• Two chambers (Primary and Secondary)
• Combustion efficiency 99.00%
• Temperature in the primary chamber is 800°C ± 50°C
• Secondary chamber gas residence time is equal to or
greater than 1.0 second at a temperature of 1050°C ±
50°C, with minimum 3% oxygen in the stack gas
• Emission standards within the required levels
• Volatile organic compounds in ash not more than
0.01%
