All electrical connections attached with the incinerator and other machinery should
be provided with suitable and necessary safety devices and be protected by steel
conduits, cable trays, and supports.
The manufacturer should permanently mark on the incinerator indicating:
(i) manufacturer’s name or trademark (ii) style, type, model or, date of manufacture
of the incinerator (iii) capacity in terms of net designed heat release in heat units
per timed period (i.e., British Thermal Units per hour, mega joules per hour,
kilocalories per hour).
Operations store “The unit shall be supplied with a lockable operations store,
that shall be initially supplied with the following consumables:
• A first aid kit, suitable for addressing the hazards presented by the unit.

• Any other consumables considered necessary by the Supplier.
The control system shall include an electronic performance monitoring and
logging system. The system shall be capable of monitoring and logging
chamber temperatures at regular intervals (not less than once per minute,
with the capacity to vary the logging frequency). The system shall include
the capacity to download the performance data by USB connection.
All the measuring devices attached with the incinerator should have
digital display and should have provision of connecting to the recording
system, which should include fuel meter and separate energy meter.
The temperature shall be determined against the inside wall of the
combustion chambers. An audible and visible alarm shall be installed to
warn the operator when the secondary temperature drops to below the required temperature.
The primary chamber must meet or exceed the following criteria:
“• Heavy steel construction.
• Fixed hearth geometry and starved air gasification operational mode.
• Hot face refractory concrete-ceramic suitable for thermal shock up to
1400 Celsius and abrasion. Minimum thickness 150mm.
• Cold face refractory lining of calcium silicate or superior material,
minimum thickness 100mm.
• Refractory lining of all the ducts shall be done with refractory castings.
Superior quality ceramic wool shall be used at all hot duct flanges and expansion joints.
• Multiple electric ignition fuel burners designed to use automotive diesel fuel.
• Flame of the primary burner shall be oriented towards the center of the
unit which does not impinge directly on the refractory floor or wall.
The secondary burner shall be positioned in such a way that the flue gas passes through the flame.
• The unit shall prevent leakage of the hot flue gas and any backfire.
• An electrically powered fan forced air supply, with the capacity for
variation by the operator.
• Digital thermometers connected to electronic dataloggers.
The thermometers shall be located on the chamber walls away from the fuel burner.
