Supply, Installation and Commissioning of An Incinerator in Eastern Hydros [ Page 28
2.2 Feeding and Fixing
E) Each of the emission to the atmosphere apart from steam or water vapour must be odourless and totally free of mist, fume and droplets.
E) A strong particulate meter/recorder ought to be supplied.
8. Burn rate (rate of waste incineration) = a least 20 kg per hour
9. Should have a complete width counterbalance loading door enabling easy access to the main room for loading and removing ash.
a) Cyclone separator
N) The minimum exit velocity must be 10 metres per second and at least twice the encompassing wind speed (Efflux velocity = wind speed x 2) whichever is higher to ensure no down washing of leaving gases.
6. The stack/chimney.
B ) The temperature of the primary chamber shall be 800 +/- 50 degrees centigrade

Incineration manufacturers To allow the Employer undertake conclusive evaluation of the tender, tenderers are asked to submit with their offers the comprehensive specifications, drawings and catalogues with commissioning and maintenance instructions for the Incinerator they intend to provide, install and commission. Tenderers who fail to obey this requirement fully shall have their tenders rejected. 2. TECHNICAL SPECIFICATIONS OF THE REQUIRED INCINERATOR
2.1 General Description
The plant must have four distinct sections that demonstrate three principles of turbulence, residence time and temperature retention. The controlled sections may include but not Limited to:
C ) The secondary room gas residence time shall be 1 second at 1050 +/- 50 degrees centigrade with 3 percent oxygen in the stack gas.
F) Make sure both secondary and primary combustion temperatures are preserved until all waste is completely combusted. The particulate collectors could include any one of the following or a combination thereof:
Capacity/island: 4000 kg/day; 25000 kg/day; 31000 kg/day; 48000 kg/day
Burning temperature — over 12000C
2 chambers — minimal
Emissions — dioxin and heavy metaly — better afterward Kyoto protocol
Emission — tracking method
Waste unloiding — directly from squander monitor to incineration
– Manual technical monitoring is sent with the hardware with explanations of failures and resolutions
2. Provision for adherence to OSHA along with other statutory requirement relating to Health and Safety of employees during execution of the functions covered in this tender.
2.6 Chimney/Stack
l) The chimney should have a minimum height of 10 metres above floor level and also clear the highest point of the building by not less than 3 metres for many roofs. The topography and height of adjacent buildings in 50 metres radius ought to be taken into consideration.
E) Make sure that the emitted oxygen content of the emitted gases is less than 11%
1.
C ) Fabric filters
B ) The room should ensure a minimal exit temperature of 850 degrees centigrade.
2.4 Secondary Combustion Chamber (After burner)
a) Should be fitted with burners using low sulphur fuel.
5.
M) The chimney ought to be visible to the operator in the feeding area.
1.
Controlled hygienic mechanical feeding that does not negatively influence the atmosphere temperature at the main and secondary chambers of the incineration shall be used.
3. Assessment and preparation and structure of a normal incineration drop with one waste storage room ( see the layout )
4. Provision of maintenance and operation manuals and drawings complete with care schedule and instructions.
5. Fuel oil storage tank- Mild steel1500 liters capacity
6. Onsite training for maintenance and operation employees.
IMPORTANT
C ) Ensure dwelling time isn’t less than two seconds.
7. Minimum capacity of main room = 0.18 cubic metres
D) Opacity of the smoke shouldn’t exceed 20% viewed by 50 metres with naked eyes.
C ) A carbon dioxide and oxygen meter/recorder ought to be supplied
d) A smoke density meter/recorder ought to be supplied.
1. Overall plant layout
Two chambers – minimum
Emissions – dioxin and heavy metaly – better then Kyoto protocol
Emission – monitoring system
Waste unloiding – directly from waste track to incineration
