Pyrotec Clinical 1.4 Clinical Incinerator Range
Pyrotec Clinical 1.4
The Pyrotec C is a modern incinerator designed to burn solid waste in a clean and environmentally safe manner. Using the Pyrolytic principles of combustion, it is particularly suited for a wide range of waste material. This model is specifically for burning clinical waste from hospitals and research centres and is equipped with the necessary sophistication of control, secondary chamber volume and gas cleaning equipment to satisfy the most stringent environmental standards. The combustion chamber arrangement comprises of a dehydration hearth and a lower troughed hearth, with waste loading taking place at the highest level. The lowest level troughed hearth has an evacuation ram to manoeuvre the residue through the chamber and finally into the ash treatment zone. This design enables batch loading during a 16 hour period with automatic ash removal on completion of the cycle.

| Secondary Chamber: one or two @ 200,000-500,000 KCal/Hr on/off control, (high/low control, automatic loading). Size to suit model. | |
| Fans |
All combustion and cooling air is provided by automatically controlled centrifugal fans which provide air to nozzles strategically located throughout the combustion chambers to ensure complete optimum conditions. |
| Preheated Combustion Air |
A heat exchanger beyond the secondary combustion chamber provides preheated combustion air for use in the primary and secondary combustion chambers to maximise efficiency and minimise auxiliary fuel usage. |
| Finish | One coat of primer followed by one coat of enamel finish in burgundy. |
| Control panel |
Automatic control system built to IEC Standards incorporating PLC controller, as necessary, providing all automatic plant functions and incorporating the following sequences.
The control panel will be equipped with an active mimic diagram, or a VDU as required, showing operating status of the plant together with the indication of the primary and secondary chambers and exhaust temperatures. |
| Loading |
Manual Loading Vertical lifting hydraulically operated, sized to suit ram loading machine. Hydraulically powered automatic fully sequenced ram loader designed to operate in unison with the incinerator operation with programmable time and temperature operating sequence to ensure maximum throughput. Water sprays around the loader throat to quench the ram face following each loading sequence. |
| Waste Handling | Waste bin tipping systems to suit 500, 650 and 1,100 litre bins designed to empty directly into the ram loader. Or conveyor loading arrangements to provide continuous sequenced loading of bagged or loose waste. |
| Gas Cleaning Equipment |
Gases from the heat recovery system are cooled to temperatures compatible with the dry gas cleaning system. The dry gas cleaning system is designed to remove contaminants from the gas stream to within specified limits using proven filtration techniques. To achieve the required degree on contaminant removal a sorbent reagent and activated carbon are introduced into the gas stream, the intimate mixing and long residence time promoted in the reaction chamber maximises absorbtion efficiencies prior to the removal of solid materials in the filtration unit. Gases pass into the filter unit and flow through a series of elements, dust particles and entrained reagent are captured on the elements, clean gases flow through to the induced draught fan and exhausted into the chimney. Removal of captured solids from the filter is by reverse jet action initiated by pressure sensors, the solid residue is discharged into a sealed skip. Ancillary equipment provided includes sorbent and activated carbon storage and transfer systems. |
|
ash removal |
Integral ashram hydraulically operated and automatic in operation together with the ash treatment zone allows for continuous ash removal throughout the burning cycle. Vacuum ash removal systems can be provided for single shift operation as an alternative. |
|
heat recovery |
Waste heat recovery boiler designed to generate hot water or steam is located between the outlet from the secondary combustion chamber and the gas cleaning system to recover energy from the hot incineration gases and reduce the gas temperature to be compatible with the gas cleaning system. Should there be no demand for energy recovery, the gases will be cooled using a heat exchanger system with air blast cooling heat dissipator. |
