UNAMID supports its dependants via the operation of several self-sustained camps located across the mission AOR. These camps contain all elements representative of small communities. These communities include hospitals and medical facilities, power generation stations, grocery shops, kitchen and dining facilities and large scale use of packaged material in plastic, cardboard and similar. The waste generated in these camps are therefore representative of average small communities without heavy industry. The main objective of this document is to provide potential bidders with necessary information to supply the large capacity containerized incinerators to UNA M I D as described in subsequent clauses.
1. Medical waste incinerator – Small
2. Medical waste incinerator – Medium
3. General waste incinerator – Small
4. General waste incinerator – Medium
5. General waste incinerator – Large
5. General waste incinerator – Large with automated feeding system
Supply of Medical and General waste incinerators
FOR THE PROVISION OF
LARGE CAPACITY CONTAINERIZED INCINERATOR AND ACCESSORIES
The proposed incinerators shall be built into standard 20ft lSO contai ners or alternatively built into similar footprint complete with ISO load handling facil ities (hooks噜 eyelets, etc). The number of conta iners/container sized modules required for each unit is at the discretion of the Contractor.
•Thermocouple
•temperature gauge
•fire rope
•burn er
•induction air fan
•digital temperature display panel
The incinerator combustion chamber(s) should be designed for easy maintenance of all internal parts including the refractory and insulation. Materials used in the individual parts of the incinerator shall be heat resistance and also be protected against oxidation, corrosion , etc. The incinerator shell shall be made of mild steel with an adequate thickness (minimum 15 mm) and painted externally with heat resistant aluminium paint suitable to withstand 250 °C. The outside surface temperature of the incinerator casing should not exceed 50 °C above ambient temperature and shall include a safety mesh around all hot surfaces. Cold face refractory lining of calcium silicate or superior material, minimum thickness 100mm.
•Heavy steel construction.
•Fixed hearth geometry and starved air gasification operationa l mode.
•Hot face refractory concrete-ceramic suitable for thermal shock up to 1400 Celsius and abrasion. Minimum thickness 150mm.
•Cold face refractory lining of calciu m si l icate or superior material, minimum thickness 100mm.
•Refractory lining of all the ducts shall be done with refractory castings. Su perior quality ceramic wool shall be used at all hot duct flanges and expansion j oints.
•Multi ple electric ignition fuel bu rners designed to use automotive d iesel fuel.
•Flame of the primary burner shall be oriented towards the center of the uni t which does not impinge directly on the refractory floor or wall. The secondary burner shall be positioned in such a way that the flue gas passes through the flame.
•The unit shal l prevent leakage of the hot flue gas and any backfire.
