Waste type: health care waste
Waste density: 125 to 350Kg/M3
Waste calorific value: 4000KCAL/kg
Moisture content: 10 – 25%
Estimated ash residue: 5 – 10%
Nominal capacity: 50kg/hr batch load
Secondary chamber: 2 [email protected]?C
Environmental: NEMA ACT (EMCA) 1999, Waste Management regulations, 2006
Primary Combustion chamber:
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 temp is not less than 850?C.
One Manual Load Incinerator comprising:
Manual loading door
Horizontal solid hearth, refractory lined primary combustion chamber. Approx. dimensions 800x2100mm(DxL)
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
Temperature indication primary and secondary chambers 0-1200?C
Refractory lined flanged chimney to a height of 10M above ground level
NB: The secondary combustion chamber must ensure that the gas temp as measured against the inside wall in the secondary chamber & not in the flame zone, is not less than 1100?C
Throughput: 50kg/hr at a nominal calorific value of 4,000kca/kg and an average bulk density of 120kg/m3 for general waste and 160kg/m3 for health care waste.
Ash: The waste will be reduced by 90~95% to leave 10-5% ash
