The forecasted feedstock loads, and daily loading rates are generally summarized as:
• Mixed general, clinical and incinerable hazardous wastes with a wide range of calorific values and densities. The wastes will consist of 100% biomedical wastes.
• Wastes either small enough to fit within a 60 litre waste sack or broken up or shredded to less than 300mm in size.
• Operation on a daytime shift basis, 5 days per week.
• An 8 hour daily operating cycle of ash removal, pre-heat and burn with continuous loading if required. The automated burn completion
Principle Medical Waste Incineration Treatment
Burn Rate Average 1000-1500 kg/hour
Feed Capacity Average 6000kg/feeding
Control Mode PLC(Programmable Logic Controller Incinerator)
Combustion Chamber 4800Liter
Internal Dimensions 400*120*100 cm
The Incinerator units shall be designed to last in operation in a tropical environment for a minimum period of 10 years if the specified maintenance schedule is followed. All metal surfaces (except combustion chamber internal fittings) shall be either galvanized, enameled, painted or otherwise treated against atmospheric and process induced corrosion
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.o C.E = (CO2 X 100) / (%CO2 +%CO)
incinerator for medical waste
Suitably designed pollution control devices such as scrubbers, filters or electrostatic precipitators, shall be installed/retrofitted with the incinerator to achieve emission limits.”
“Each unit shall include a complete vertical exhaust and stack system, including the following features:
• Steel construction.
The proposed incinerators shall be able to be completely packed into a series of 20ft export standard sea containers.
• Refractory lining in the lower section.
• The exit height of the stack shall be not less than a range of 3-12 metres above ground level depending on the capacity of the incinerator unit.
The incinerator shell shall be made of mild steel with an adequate thickness for small units of between 3-6mm and larger units 5-10 mm depending on the construction part and painted externally with heat resistant aluminum 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 100 mm.
The incinerator units shall include a temperature based electronic combustion control system that utilizes temperature and other data to inform automated or programmed cycling through the standard burn cycle: pre-heat, burn with waste addition, burn completion, cool-down. The system shall be capable of varying auxiliary fuel and air supply in both combustion chambers to achieve optimum combustion conditions. As far as practicable, the incinerator shall be of a plug and play type for ease of installation and commissioning in remote locations.
“The control system shall have a separate push button-based work station, which shall be located adjacent to the loading bay and protected from weather and impact damage. The system shall allow for rapid and straightforward intervention by the operator if the automatic system is not achieving the desired results during a burn cycle.
e. achieve a Total Organic Carbon (TOC) content in the slag and bottom ashes of less than 3%.
g. include clearly readable system operation panels.
h. include an operator’s manual (in English and French and Spanish).
i. require minimal preprocessing i.e. there shall be no/very limited need for prior sorting, crushing or shredding.
j. be capable of handling mixed solid waste streams and incinerable hazardous wastes as indicated.
k. can accommodate large variations in waste composition and calorific value.
l. allow for batch loading
The control system shall include an electronic performance monitoring and logging system. The system shall be capable of monitoring and logging chamber temperatures at regular intervals (not less than once per minute, with the capacity to vary the logging frequency). The system shall include the capacity to download the performance data by USB connection.
All the measuring devices attached with the incinerator should have digital display and should have provision of connecting to the recording system, which should include fuel meter and separate energy meter.
The temperature shall be determined against the inside wall of the combustion chambers. An audible and visible alarm shall be installed to warn the operator when the secondary temperature drops to below the required temperature.
The primary chamber must meet or exceed the following criteria:
• Multiple electric ignition fuel burners designed to use automotive diesel fuel.
• Flame of the primary burner shall be oriented towards the center of the unit 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 shall prevent leakage of the hot flue gas and any backfire.
• An electrically powered fan forced air supply, with the capacity for variation by the operator.
• Digital thermometers connected to electronic dataloggers. The thermometers shall be located on the chamber walls away from the fuel burner.
