The incinerator should be a modern waste disposal unit, designed to bum medical waste in a clean and environmentally efficient manner. It
should employ a temperature based logic control system to provide optimum control of the operating conditions and incorporate a high capacity
thermal oxidizing secondary chamber. It should be designed to retain the exhaust gases, for at least 2 seconds to ensure the unit’s effective
destruction of the combustion products.
i. Waste type Health care waste
ii. Waste density 125 to 350Kg/M3
iii.. Waste Calorific Value 4000 KCAL/Kg
iv. Moisture content 10-25%
v. Estimated ash residue 5-10%
vi. Nominal capacity 50Kg/hour batch load
vii. Secondary chamber 2 seconds @ 850°C
The primary combustion chamber is the main structure of the incinerator, fabricated from mild steel plate and stiffened with rolled steel
sections. It is carried from the floor level on a substantial steel support frame. Internally the shell is lined with calcium silicate
insulation and a hot face combination of super duty brickwork or high strength castable.
The primary combustion chamber must ensure minimum exit temperature is not less than 850°C.
One Manual Load Incinerator comprising:
• Manual Loading door
• Horizontal solid hearth, refractory lined primary combustion chamber. Approximate dimensions 800 mm diameters x 2100mm long
• Full sized bulk load/ash removal door
• 1 off diesel-fired ignition burner — temperature controlled
• 1 off combustion air supply fan and distribution system, automatic control
• High capacity secondary combustion chamber with residence time not less than 2 seconds @ >850°C
• 1 off diesel-fired afterburner — temperature controlled
• Control panel — automatic operation
ð Temperature indication primary and secondary chambers 0-1200°C
ð Refractory lined flanged chimney to a height of 10M above ground level
50kg/hour at a nominal calorific value of 4,000 kcal/kg and an average bulk density of I20kg/ M3 for general waste and l60kg/ M3 for health
care waste.
