Maintenance
63
–
the lack of water below the set level
–
the lack of insulation inside the probe
–
faults inside the device (self-check)
–
interruption of the connection between the probe and the device in compliance with
EN 12953-9 point 5.4.8.
When it trips, the control panel triggers a visual and an acoustic alarm and stops the generator (permanently). The generator
operation is resumed only after the elimination of the fault and the manual reset by the operator. The control panel is supplied
fully assembled on the generator and already tested.
It complies with the following European Directives:
– Low Voltage Directive 2014/35/EU
– EMC Directive 2014/30/EU
– PED Directive 2014/68/EU
Salinity control unit
(
TDS
- only for
ECOVAPOR 72
) consisting of:
–
conductivity probe
–
salinity regulation and control unit
–
electric or pneumatic blowdown system complete with shut-off valves
–
electrical controls in generator control panel
–
mechanical and electric assembling.
The
TDS
control system limits the salt and mineral levels dissolved in system water within permitted manufacturer values, thus
avoiding any risk of entrainment due to high salinity levels and minimising the amount of blowdown required and associated
costs. The system continually measures the electrical conductivity value of the system water, just below the evaporation surface.
Its value is related to the concentration of dissolved salts. The detected value is compared with the set one. If it is higher, the
blowdown valve opens until the value returns below the set-point.
Automatic sludge drain unit
(only for
ECOVAPOR 72
), to prevent sludge build-up inside generator, it consists of:
–
2-way pneumatic valve made of steel, with lever for manual operation
–
adjustment of opening frequency and duration
–
compressed air solenoid valve
–
connections and electrical controls in generator control panel
–
mechanical and electric assembling.
The automatic sludge drain unit prevents unnecessary blowdown duplication or verifiable omission with the manual system.
This system allows sludge accumulated at the bottom of the boiler to be regularly and automatically removed through a cyclical
opening in the blowdown valve. The blowdown frequency and duration are set by the user according to the characteristics of the
generator water, as indicated in this technical manual. The system requires compressed air availability.
High level safety probe
, mounted directly in the generator body.
Kit designed to prevent an excessive increase of water level inside the generator. Once the set level is reached, the control panel
stops the feed pump and triggers an acoustic alarm. Alarm resetting and pump restart automatically occur once normal level in
the generator is restored.
Cooler for samples
, directly fitted inside the generator, consisting of:
–
AISI 304 barrel with an internal water-cooling coil
–
cooling water injection ball valve
–
handwheel valve for sample picking.
Make sure that the boiler is operating within the desired conductivity parameters by taking and testing water samples. To safely
obtain samples, it is essential that a proper cooling is carried out in order to condensate any rising steam before the withdrawal
point. The cooler reduces the water temperature to 25° C so that it is ready for an immediate sampling.
Integrated energy saver
consisting of:
–
2 check thermometers
–
1 pressure gauge with three-way test valve
–
safety valve.
Temperature monitoring
:
–
ambient temperature
–
flue gas temperature.
