incinerators

  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 kinds of diesel fired incinerations acceptable for HCW may be offered as long as they can

safely treat medical waste. The gear ought to be compliant with all requirements for

installment in Kenya. All components for installation must be included.

 Technical evaluation will consider the entire system including the treatment plant. It’ll be

that the responsibility of the Bidder to provide a full system, including all essential secondary

systems and/or extra gear.

An approved plant must have four different sections that demonstrate three fundamentals of

Turbulence, Residence Time and Temperature inbuilt in the plant design .The regulated segments

may include but not restricted to:

 Total plant design

 Feed chamber/ charging

 Main Combustion Chamber

 Secondary Combustion Chamber

 Particulate Scrubbers

 Acid Gas Scrubbers

 The stack/ chimney

To the primary incineration process, a static, 2 chamber system is required with one major

combustion chamber and one flue gas afterburning chamber. The incineration must be able to

meet these parameters:

1,100 °C

The furnace (including secondary combustion chambers etc.) measurements must be big enough

to supply a successful blend of gas residence time and temperature such that

  1. Treatment capacity of: a) 50 kg waste per hour.
  2. Temperature: Main combustion chamber up to 850°C, and in the second chamber > =

combustion reactions may approach conclusion and result in low and stable CO and VOC

  1. Retention Time: 2 seconds in the second chamber

emissions.

so as to avoid the production poisonous gases, the incineration must unite the gasification or

pyrolysis phase with a subsequent combustion phase with flue-gas treatment that gives for

usable emission levels to air within the related emission ranges specified in the criteria

5

for incinerations which are described in the ENVIRONMENTAL MANAGEMENT AND COORDINATION

(WASTE MANAGEMENT) REGULATIONS 2006 of the Republic of Kenya.

Where grates are utilized, it’s preferred that the design incorporates sufficient cooling of the

grate so it allows the variation of the principal air supply for the primary intention of

combustion control, rather than for the cooling of the grate itself. Documents to be

Offered by the Bidder in response to this RFP.

 Complete information on how the equipment matches the Technical Specification.

Contain an extra statement with a calculation and description of all cost about the

normal running of the plant over a 12 month period.

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

 Lay out drawing together with all principal equipments, flue gas ductwork and chief piping.

 Piping and Instrumentation Diagram.

 Operation guide at the English language.

 Materials lists.

 Implementation plan and training idea.

 Installation and maintenance plan.

 Detailed list associated with wear and spare part package for 2500 h performance (items which

is going to be included in the contract). The list ought to be detailed enough to permit PATH to

carry out a cost estimation.

Other information like process description, brochures, etc. ought to be only added if

the information will be useful for the technical evaluation of the treatment process.

 

A2) Technical Specification:

Medical Waste Autoclave

 

Manual autoclave with vertical loading; gravity displacement form with possibility for Vacuum.

 Shall work according to gravity air displacement principle.

 The vacuum system shall function as a thermal shock type.

6

 The pressure vessels ought to be pressure tight, the climbing of the pressure (at a start pressure

of under 80 mbar) will be reduced than one mbar/min.

 Together with in-build electrical heating elements for steam production (heating elements > 4000

Kw).

 Chamber and door shall be created from top quality stainless steel (e.g. AISI 3161).

 Chamber in vertical position, it will allow an easy loading/unloading of the loading

basket. The baskets

will be made for the use of non-heat resistant waste luggage, a method for the

set and controlled release of free liquids and condensate from the waste will likely be

integrated.

 The temperature measured at the reference measurement point of the treatment chamber

will not be lower than 105°C (TDes 0+4). The treatment time will likely be ≥30 minutes at

105°C, ≥20 minutes with a temperature utilized of ≥121°C (TDes 0+4) and ≥10 moments

with a treatment temperature of ≥ 134.

 The steering of the treatment process should be semi-automatically as well as manual.

 The Remedy Equipment will be equipped with the following instruments:

o treatment chamber temperature indicating instrument

o treatment chamber pressure indicating instrument

 For treating the outgoing air, a HEPA filter together with a condensation

system ought to be used.

 The filter will probably be constructed in a way that a disinfection of the filter will be possible in a builtin

condition.

 The filters must be heat resistant, steam resistant, hydrophobic and worry resistant for

the pressure difference.

 Cooling down stage after treatment ought to be existing; the temperature of the waste

ought to be not greater than 80°C after finishing the cooling down process.

 The pressure vessel ought to be equipped with a heat insulation, the highest outer

surface temperature ought to be < 50°C.

 The manufacturer should offer a declaration that the pressure vessel is produced in

accordance with relevant guidelines for pressure equipment.

Following accompanying documents should be provided together with the treatment system and

will be available at the Website:
