2.9 Exhaust Purview
a) Combustion performance (C.E) shall go to the minimum 99.00percent where C.E =%Co2 x 100/ [% Co2 + carbon monoxide gas] b) The temperature level of the principal chamber will be 800 +/- 50 degrees centigrade.
1. Total plant format
C ) The secondary chamber gas home time will go to least 1 2nd in 1050 +/- 50 degrees centigrade with 3 percent oxygen in the stack gas.
6. The stack/chimney.
E) All the discharge to the atmosphere apart from vapor or water vapour ought to be odorless and without mist, fume and beads.
4. Particle scrubbers
G) The average dioxin and also furan concentration in the exhaust shouldn’t go beyond 80mg/m3 total dioxins and furans if gauged for a duration of 6 to 16 hrs.
– – Guidebook technological monitoring is sent with the equipment with all explanations of failings as well as resolutions.
C ) A carbon monoxide gas and also oxygen meter/recorder ought to be offered
d) A smoke thickness meter/recorder have to be provided.
3. Key combustion chamber
E) A strong particulate meter/recorder ought to be supplied.
E) Ensure the discharged oxygen web content of the emitted gases is less than 11%.
2. Stipulation for adherence to OSHA as well as other statutory requirement relating to Health and Safety of workers during execution of the works covered in this tender.
M) The smokeshaft ought to be visible to the driver from the feeding place.
D) Guarantee that the gas temperature as gauged versus the inside wall in the extra chamber rather than in the fire area isn’t less than 1100 levels centigrade.
2.3 Primary Burning Chamber.
a) This chamber have to be equipped with burners that take advantage of low sulphur gas.
Capacity/island: 4000 kg/day; 25000 kg/day; 31000 kg/day; 48000 kg/day
Burning temperature– over 12000C
Two chambers– minimum
Exhausts– dioxin and also hefty metaly– much better then Kyoto process
Emission– monitoring system
Waste unloiding– directly from waste monitor to incinerator
a) Instrument for figuring out the inside wall temperature and not burner fire temperature has to be attended to both key and also secondary chambers.
N) The minimum leave rate have to be 10 metres per second as well as at the very least twice the surrounding wind speed (Efflux rate = wind speed x 2) whichever is higher to make certain no down cleaning of leaving gases.
1. Supply, mount as well as appoint a burner as given in the technical specs
9. Ought to have an entire size counterbalance loading door allowing very simple access to the main chamber for loading as well as removing ash.
3. Stipulation of procedure and upkeep manuals and drawings complete with upkeep schedule and guidelines.
5. Gas oil storage tank- moderate steel1500 litres capacity
6. Onsite training for operation as well as maintenance team.
Incinerator producers To allow the Employer undertake definitive evaluation of the tender, tenderers are asked to ship with their deals the thorough specifications, illustrations and catalogues with commissioning and maintenance instructions for the Burner they intend to supply, setup and commission. Tenderers that fail to follow this demand fully will have their tenders denied. 2. TECHNOLOGICAL REQUIREMENTS OF THE REQUIRED INCINERATOR
2.1 General Summary
The plant has to have four different sections that reveal 3 concepts of turbulence, house time and also temperature retention. The managed areas may include however not Limited to:
C ) Textile filters.
F) A 99.99% destruction and elimination performance (DRE) for every main natural dangerous element (POHC) in the waste feed in which DRE [( Success – – Wout )/ Win] x 100 where Success = mass feed rate of the POHC in the waste stream fed to incinerator and Wout = mass emission rate of POHC in the stack prior to the release to the atmosphere.
5. Acid gas scrubbers.
F) Guarantee both main as well as second combustion temperature levels are preserved up till all waste is completely ignited.
2.5 Particulate Removers
A mechanical particle enthusiast have to be integrated after second burning chamber for removal of particulate toxins entrained in the flue gas stream. The particulate collectors may consist of some of the complying with or a mix thereof:.
D) Opacity of the smoke need to not surpass 20% seen from 50 metres with naked eyes.
l) The chimney should have a minimal elevation of 10 metres above ground level as well as clear the acme of the construction by not less than 3 metres for all roofs. The topography as well as elevation of adjacent structures within 50 metres radius has to be taken into consideration.
B) Guarantee second air distribution is controlled.
C) Make sure house time isn’t less than two seconds.
Exhausts– dioxin and also hefty metaly– much better then Kyoto procedure
Emission– monitoring system
Waste unloiding– directly from waste track to incinerator
