waste and average temperature of 8500 degress c.

1. The publications listed below form a part of this specification to the extent referenced. The publications are

referenced in the text by basic designation only.

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

For the main incineration process, a static, two chamber system is required with one main

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

5

for incinerators which are described in the ENVIRONMENTAL MANAGEMENT AND COORDINATION

(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.
