Combustion Efficiency 99.99%
Retention time Of the flow gases not less than 2 Sec in the hot portion.
Excess Oxygen concentration Of primary combustion chamber 3-6% max.
Refractory The chambers should be lined with high thermal insulating refractory bricks with suitable thickness and
with highly temp. resistance. Not less than 1400 C for the first combustion chamber, and not less than 1600 C for the
secandry combustion chamber, and at the same time prevent the Temp. of the outside body of the chamber not higher than
Doors Should be lined with the same bricks, and the edges lined with special suitable insulating material to prevent
any gas escaping, and the doors should be kept under negative pressure during the operation.
Air Emission Control System With high destruction and removal efficiency (DRE). Not less than 99.9999 as per KEPA.
Wet System If the system equiped with a CEMS washing the flow gas with water, then it should be manufactured from
suitable anti corrossion materials, and equiped with pH meter to measure and neutralize the water. It should be able to
use the water in closed recycled circuit many times before treating/ discharging into the sewage system in compliance
Chemical dosing It should be equiped with suitable autochemical dosing system to control the pH for the water of the
wet scrubber system including sensors.
Chimney It should be suitable with the capacity and the technical specifications, with height not less than 12m from
ground level. With easy opennable sampling point equal about 3 inch, and the optimum sampling locations is at least 8D
downstream direction and 2D upstream from any flow disturbancies.
Sampling point Should be equiped with a platform located down the sampling point by a distance not less than 1 m, and
equiped with suitable stairs from ground to the port with comfortable slope.
Ash Removal It should be auto ash removal system.
Fuel It should be dual system, such as diesel and natural gas.
Feeding System Should be auto feeding system into primary chamber.
Control Room Should be equiped with a control panel shows Temp. of the combustion burners, gas monitoring, digital
Temp. indecation for the primary/secondary chambers, digital Temp. indication for the gases…etc. it should be also
Auto operation, burnures on/off auto lamps switch, auto start/stop for air emission control system, auto gas continuous
monitoring system reading and print out of gas emission parameters…etc.
Cooling System The primary chamber should be provided with auto cooling systemthrough nozzles to permit direct cooling
if the Temp. will be heigher than 1100 C.
Inter-lock system The incinerator should be equiped with inter-lock system to prevent feeding the waste to the
primary chamber if the combustion Temp. less than 500 C.
Flue treatment and cleaning To consist a combined system (wet/dry), using water, lime, active carbon and ceramic
Quenching system/Heat exchanger Should be made and manufactured from anti corrosion and acid attack materials such as
stainless steel 316 or equivalent.
Noise Level Not more than 85 dBA during normal operation.
Inaddition The desigh should insure that responsive fail-safe control systems are used.
The incinerator should be installed inside closed suitable building with good aeration and ventilation system.
The building has facilities for off-loading of wastes from transport vehicles. Auto cleaning system for trucks and
waste containers, and cool storage area…etc.
The quotation should included list of original spare parts for 7 years.
The quotation should include supervising, starting up and training of the operators and ministry of health
engineers inside/outside Kuwait.
Detailed drawings, catalogs should be included.Our normal activities generates 2-5 tons of assorted waste
materials per day which range from condemned carcasses, and other wastes all which need to be incinerated at above
800Centigrade measured flue exhaust gas.
