A1) Technical Specification: Incinerators

 

All types of diesel fired incinerators suitable for HCW may be offered as long as they can safely treat medical

waste. The equipment should be compliant with all requirements for installation in Kenya. All components for

installation must be included.

 

Technical evaluation will consider the entire system including the treatment plant. It will be the responsibility of

the Bidder to supply a full system, including all necessary secondary systems and/or additional equipment.

 

The calorific value of the generated waste from the healthcare facilities differs from 5,000 kJ/kg (e.g. pathological

waste) up to 40,000 kJ/kg (filled sharp boxes) with an expected average heating value of waste of 14,000 kJ/kg.

 

An approved plant must have four distinct sections that demonstrate three principles of Turbulence, Residence Time and

Temperature inbuilt in the plant design .The regulated sections may include but not limited to:

 

Overall plant layout

 

Feed chamber/ charging

 

Primary Combustion Chamber

 

Secondary Combustion Chamber

 

Particulate Scrubbers

 

Acid Gas Scrubbers

 

The stack/ chimney

combustion chamber and one

flue gas afterburning chamber. The incinerator must be able to meet the following parameters:

 

1.Treatment capacity of: a) 50 kg waste per hour.

 

2.Temperature: Main combustion chamber up to 850°C, and in the second chamber > = 1,100 °C

 

3.Retention Time: 2 seconds in the second chamber

 

The furnace (including secondary combustion chambers etc.) dimensions must be large enough to provide for an effective

combination of gas residence time and temperature such that combustion reactions may approach completion and result in

low and stable CO and VOC emissions.

 

In order to avoid the generation toxic gases, the incinerator must combine the gasification or pyrolysis stage with a

subsequent combustion stage with flue-gas treatment that provides for operational emission levels to air within the

associated emission ranges specified in the standards

 

 

for incinerators which are described in the ENVIRONMENTAL MANAGEMENT AND CO-ORDINATION (WASTE MANAGEMENT) REGULATIONS

2006 of the Republic of Kenya.

 

Where grates are used, it is preferred that the design incorporates sufficient cooling of the grate such that it

permits the variation of the primary air supply for the main purpose of combustion control, rather than for the cooling

of the grate itself. Documents to be provided by the Bidder in response to this RFP.

 

 Complete information on how the equipment matches the Technical Specification. Include an additional statement with

a calculation and description of all cost related to the normal running of the plant over a 12 month period.

 

Full description of the system(s) being proposed.

 

Lay out drawing with all main equipments, flue gas ductwork and main piping.

 

Piping and Instrumentation Diagram.

 

Operation manual in the English language.

 

Material lists.

 

Implementation plan and training concept.

 

Installation and maintenance plan.

 

Detailed list related to wear and spare part package for 2500 h operation (items which will be included in the

contract). The list should be detailed enough to allow PATH to carry out a cost estimation.

 

Other information such as process description, brochures, etc. should be only added if the information will be useful

for the technical evaluation of the treatment process.

Chamber in vertical position, it shall allow an easy loading/unloading of the loading basket.

 

2 Baskets of >100 l for the loading and unloading of waste shall be included. The baskets shall be designed for the

usage of non-heat resistant waste bags, a system for the collection and controlled release of free liquids and

condensate from the waste shall be incorporated.

o   treatment chamber temperature indicating instrument

otreatment chamber pressure indicating instrument

For the treatment of the outgoing air, a HEPA filter in combination with a condensation system should be used.

The filter shall be built in a way that a disinfection of the filter shall be possible in a built-in condition.

 

The filters must be heat resistant, steam resistant, hydrophobic and pressure resistant for the pressure difference.

 

Cooling down phase after treatment should be existent; the temperature of the waste should be not higher than 80°C

after finishing the cooling down process.
