2.1 - GENERAL DESCRIPTION
OF THE RANGE

TECHNICAL FEATURES
AND DIMENSIONS
The series of high pressure steam generators, with smoke
pipes, with flame blowing furnace, high performing BAHR'12
Unical STEAMER is designed for a maximum allowable pres-
sure PS = 12 bar.
The range includes no. 15 models with a steam production of
300 kg / h (nominal power = 204 kW)
at 6000 kg / h (nominal power = 4089 kW).
The BAHR '12 range of generators is made up of the following
versions:
OR
suitable for operation with gas burners, gas oil or fuel
oil
STD
suitable for operation with gas burners, gas oil or fuel oil
HP0
suitable for operation with gas burners, gas oil
HP
suitable for operation with gas burners
EC
To further improve the already high value performance of
the generator, without influencing the sizes, the BAHR’12
STD, HPO and HP models are already provided for mount-
ing, on request, (already in the factory or at a later time),
the EC economiser composed of:
• a finned pipe carbon steel exchange coil, which can be
easily inserted into the rear smoke chamber (drawer in-
sertion);
• a modulating or inverter supply valve
• electrical components;
• processing pipes.
The EC kit is specific for each model and requires, in combina
-
tion, the water level modulation unit.
The single-block version generator supplied is composed of the
following units:
A) Boiler body complete with:
- manhole,
- front door full with flame warning light and blind plate for
connection to burner,
- smoke chamber complete with inspection door and clean-
ing and flue outlet fitting,
- rock wool insulation coating and pre-painted aluminium
casing.
B) Finishing assembly consisting of:
- stream line flow valve as main steam outlet
- 2 spring safety valves
- blind flange on the secondary steam outlet
C) Assembly control panel
on request the generator can be equipped with 3 different
types of control panel (BASIC, BMI or IML) and relative ac-
cessories connected to them (that can be connected).
BASIC
control board composed of:
- BASIC control panel including wiring (pressure gauges,
probes, burner power),
- no.4 level probes (min, max, safety)
- no. 2 probe holder flanges,
- no. 2 level indicators,
- manifold with pressure gauge, 3 way valve, pressure
switches (2 c 1 safety)
BMI
control board composed of:
- BMI control panel including wiring (pressure gauges,
probes, burner power),
- no.4 level probes (min, max, safety),
- no. 2 probe holder flanges,
- no. 2 level indicators,
- manifold with pressure gauge, 3 way valve, pressure
switches (2 c 1 safety)
IML
control board composed of:
- IML control panel including wiring (pressure switches, lev-
el gauges, probes, burner power),
- no. 3 level probes (2 safety, 1 set),
- barrel with capacitive probe
- no. 2 probe holder flanges,
- no. 1 level indicator,
- manifold with pressure gauge, 3 way valve, pressure
switches (1 c 1 safety), pressure transducer.
D) Supply unit
on request the generator can be equipped with 1 or 2 pumps.
1 pump
unit composed of:
- shut-off valve + check valve,
- 1 pump complete with wiring,
- support base
2 pumps
unit composed of:
- 2 shut-off check valve,
- 2 pumps complete with wiring,
- support base
E) Boiler drain unit
on request the generator can be equipped with automatic
discharge.
F) Salinity control unit (TDS)
on request the generator can be equipped with the TDS 1 or
TDS2 salinity control unit.
The salinity control unit is composed of:
- shut-off valve
- relief valve
- conductivity probe (CP30 x TDS 1 - CP32 x TDS 2)
- solenoid valve
- wiring connections
G) Water level modulation unit
on request the generator can be equipped with water level
modulation unit for systems with:
-
1 or 2 pumps
NOTE:
Normally, the generators are supplied fully
assembled. In particular cases, to avoid dam-
age during transportation or handling, some
units are supplied unassembled.
For the reassembly, refer to the instructions
supplied together with the documentation
supplied with the device.
