Medical Incinerator Specification
Capacity Not less than 500Kg/hr. Operation 24hr-7days/week continuous operation. Combustion chamber 2 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 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 70 C. 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 with KEPARS. 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
