CapacityNot less than 500Kg/hr. Operation24hr-7days/week continuous operation. Combustion chamber2 combustion chamber. Temp.First combustion chamber 800-1000 C. Secandry combustion chamber 1000-1200 C, with the possibility to be upgraded to 1400 C. Combustion Efficiency99.99% Retention timeOf the flow gases not less than 2 Sec in the hot portion. Excess Oxygen concentrationOf primary combustion chamber 3-6% max.
RefractoryThe 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 70 C. DoorsShould 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 SystemWith high destruction and removal efficiency (DRE). Not less than 99.9999 as per KEPA. Wet SystemIf 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 with KEPARS. Chemical dosingIt should be equiped with suitable autochemical dosing system to control the pH for the water of the wet scrubber system including sensors. ChimneyIt 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 pointShould 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 RemovalIt should be auto ash removal system. FuelIt should be dual system, such as diesel and natural gas. Feeding SystemShould be auto feeding system into primary chamber. Control RoomShould 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 SystemThe 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 systemThe 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 cleaningTo consist a combined system (wet/dry), using water, lime, active carbon and ceramic filters. Quenching system/Heat exchangerShould be made and manufactured from anti corrosion and acid attack materials such as stainless steel 316 or equivalent. Noise LevelNot more than 85 dBA during normal operation. InadditionThe 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.
