The incinerator with “PYROLYTIC” combustion

The incinerator control panel shall have all appropriate audible and visual alarms to ensure safe operation. 
This incinerator with “PYROLYTIC” combustion must have: 
1.A combustion chamber of waste: 
oPerfectly tight door for the manual loading of waste. The loading should be Manual, Batch Load 
oA burner of lighting which the use is limited to the ignition of waste. 
oFrontage of loading with door seals gone up on hinges, wheel of screw plug, flexible joint, and stuffing insulating out of refractory. 
oThe insulation of the combustion chamber should be composed of refractory bricks, having a high content of aluminium and insulates bricks in order to assure a minimum temperature on the outside sheet metal.
o Composition of the refractory;

Refractory concrete :
. Thickness : ≥100 mm
. Nature: 42% of Al203
Insulate in fibrous panels :
Thickness: ≥75 mm
Nature: Calcium silicate.
Burner of lighting of waste, with fuel, standard mono-bloc casting guiding  plunging flame, lighting and safety of electronic ignition, permanent ventilation, electromagnetic sluice gate of regulation and isolating valve. 
Plate of combustion in Carborundum, avoiding the fixing of glass and slags

A chamber of post combustion of gases 
oA burner of combustion of gases, 
oA device of injection of air allowing a total recombustion of gases, 
oA device of air inlet of cooling of waste gases, 
oA sheath of evacuation of the gases burnt. 
oCarcass in strong sheet steel with support of connection. 
oComposition of the refractory;
Refractory concrete :
Thickness : ≥150 mm
Nature: 65% of Al203
Insulate in fibrous panel :
Thickness: ≥85 mm
 Nature: Calcium
oBurner with fuel, mono-bloc casting guiding type with horizontal flame, lighting and safety of electronic ignition, permanent ventilation, electromagnetic sluice gate of regulation and isolating valve. 
oA secondary injection of air to ensure perfect oxygen content. 

A control box ensuring the complete cycle of combustion. 

Fan: 
oElectro-ventilator distributing the secondary air, the regulation of the air flow being carried out by valves and following the control of the automatic cycle. 
Controls and regulations: 
Control box watertight to dust, including: 

A switch circuit breaker for each engine (ventilators and burners). 
A timer with adjustable temporization for the regulation of each burner. 
A regulator with digital watching for the temperature of combustion. 
A regulator with digital watching for the temperature of post combustion. 
Electric box

The secondary combustion chamber must destroy the contaminant product and must resist to high temperature(1100 °C)

Process Filtering system: Scruber to be mentionned as optional
Emission Standards Compliance: BS 3316 or équivalent standard

Capacity to treat Plastic: Not less than 40% by weight

PECIFICATIONS OF A PYROLYTIC MEDICAL WASTE INCINERATOR

An incinerator represents a complete solution to the problem of disposal of all hospital waste types. The liquid fuel is diesel. The incinerator should meet the environment standards. 
Expected Technical specifications

The incinerator shall be fully self contained. 

The incinerator plant shall incorporate a control panel for its operation. On the control panel we shall have a visual display of the chamber temperatures. This visual display must control and monitor the incinerator and his performance.

Capacity of destruction in weight shall be 60 Kg/h. 

It should be able to operate not less than 10 hours/day

This incinerator must be able to destruct all combustible wastes produced by hospitals, private clinics, laboratories, institutes, etc… 

Design Specification : Types A, B, C, D, and E of medical waste 

“PYROLYTIC” combustion, by controlling the gasification of waste. 

The incinerator must avoid the release of black smoke and fine dust, during the loadings.

It shall be able to reduce the volume of wastes by 98%.

It shall be able to hold emission in the second burn with gas residence of not less than 2 seconds. 

The incineration should be completely free from visible smoke as well as offensive odours. 

1.0The primary ignition burner shall providing ignition of the waste to 850 °C and must switch off to conserve fuel.

The primary combustion chamber shall be constructed from heavy steel plate and the unit is internally lined with a complete layer of hote face refractory and high efficiency insulation. 

The Internal diameter of the Chimney at least: Ø 400 and its height: 8 m 

The Volume of the combustion chamber at least: 1.200 L 

The Dimension of the door for loading in cm at least: 70×70. 

Burner operation should be Automatic On/Off  
Fuel : diesel
