3. Key combustion chamber
4. Particle scrubbers
5. Acid gas scrubbers.
6. The stack/chimney.
7. Minimum capability of key chamber = 0.18 cubic metres
8. Shed rate (rate of waste incineration) = a least 20 kg per hr
9. Ought to have a complete size counterbalance loading door allowing very easy access to the primary chamber for loading as well as removing ash.

2.2 Feeding and also Charging
Regulated hygienic mechanical feeding that does not adversely influence the air temperature level in the key and also second chambers of the burner shall be utilized.
2.3 Main Burning Chamber.
a) This chamber need to be equipped with burners that make use of low sulphur gas.
b) The chamber should guarantee a minimal leave temperature level of 850 levels centigrade.
2.4 Secondary Burning Chamber (After burner)
a) Should be fitted with heaters that utilize low sulphur gas.
b) Guarantee second air supply is controlled.
c) Make sure house time is not less than two seconds.
d) Guarantee that the gas temperature as gauged versus the within wall in the additional chamber and not in the flame area is not less than 1100 levels centigrade.
e) Make sure the discharged oxygen web content of the emitted gases is not less than 11%.
f) Guarantee both main as well as second combustion temperature levels are preserved up until all waste is completely ignited.
2.5 Particulate Removers
A mechanical particle enthusiast have to be incorporated after second burning chamber for removal of particulate toxins entrained in the flue gas stream. The particulate collectors may consist of any of the complying with or a mix thereof:.
a) Cyclone separator.
b) Electrostatic precipitators.
c) Textile filters.
2.6 Chimney/Stack
l) The chimney should have a minimal elevation of 10 metres above ground level as well as clear the acme of the structure by not less than 3 metres for all roofs. The topography as well as elevation of adjacent structures within 50 metres radius must be taken into consideration.
m) The smokeshaft ought to be visible to the driver from the feeding location.
n) The minimum leave rate need to be 10 metres per second as well as at the very least twice the surrounding wind speed (Efflux speed = wind speed x 2) whichever is higher to make certain no down cleaning of leaving gases.
o) The point for dimension of discharges will be offered.
2.7 Instrumentation
a) Instrument for figuring out the inside wall temperature and also not burner fire temperature must be attended to both key and also secondary chambers.
b) A distinct and also visible alarm need to be mounted to alert the operator when the second chamber temperature level goes down to listed below the called for temperature.
c) A carbon monoxide gas and also oxygen meter/recorder should be offered
d) A smoke thickness meter/recorder need to be provided.
e) A strong particulate meter/recorder ought to be provided.
f) Any kind of various other instrument that might be taken into consideration essential.
2.9 Exhaust Purview
a) Combustion performance (C.E) shall go to the very least 99.00% where C.E = %Co2 x 100/ [% Co2 + carbon monoxide gas] b) The temperature level of the primary chamber will be 800 +/- 50 degrees centigrade.
c) The secondary chamber gas home time shall go to least 1 2nd at 1050 +/- 50 degrees centigrade with 3% oxygen in the stack gas.
d) Opacity of the smoke need to not surpass 20% seen from 50 metres with naked eyes.
e) All the discharge to the air apart from vapor or water vapour should be odorless and without mist, fume and beads.
f) A 99.99% destruction and elimination performance (DRE) for every primary natural dangerous component (POHC) in the waste feed where 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 before the release to the atmosphere.
g) The average dioxin and also furan concentration in the exhaust must not go beyond 80mg/m3 total dioxins and furans if gauged for a duration of 6 to 16 hrs.
– – Guidebook technological monitoring is shipped with the equipment with all explanations of failings as well as resolutions.
