DESCRIPTION OF INDUSTRIAL BURNERS
The
GI 1000 burner is a packaged version made up of
separately supplied units; these components must be
connected at the burner installation site in full observ-
ance of the instructions given by
BALTUR.
A -
Combustion head with fan
B -
Power board
C -
Pumping unit for liquid fuels. If heavy oil is to be
used this unit also includes an electric heavy oil preheater
and, on request, an auxiliary steam preheater.
D -
Gas valve unit for burners employing gaseous
fuels (usually methane).
These burners are available in a range of versions to
suit the employed fuel type. More specifically, these are:
-
GAS (Methane) version GI 1000 DSPGN
-
LIGHT OIL version GI 1000 DSPG
-
HEAVY OIL (rated viscosity max. 50°E at 50°C) ver-
sion
GI 1000 DSPN-D
- GAS (Methane) / HEAVY OIL (rated viscosity max.
5°E at 50°C) version
GI-Mist 1000 DSPNM
- GAS (Methane) / LIGHT OIL version GI-Mist 1000
DSPGM
Note that the
GI-Mist 1000 DSPGM and GI-Mist 1000
DSPNM burners have been designed for operation with
methane gas or with liquid fuel.
-
The “GI 1000” burner is a modulating burner with a modula-
tion range of 1 - 4. Adjustment to current heat requirements
is provided by means of a servomotor that regulates the
combined quantity of combustion air and fuel according to
the signals from the in-boiler probe.

the cross-section of the air passage in the combustion head,
doing so proportionately to variations in load. This device
gives optimum combustion under all load conditions as a
result of optimisation of the air/fuel mix; there thus results
reduced excess of air with better quality combustion.
FIXING THE BURNER TO THE BOILER
The burner must be fitted to the iron boiler plate where
the supplied studs have been fitted in place beforehand
in observance, of course, of the drilling template. It is
advisable to electrically weld the studs from the inter-
nal part of the plate so that they are not, in the event
of burner disassembly, extracted together with the unit
lock nuts. If there is no thermal insulation on the plate
then an insulating layer at least 10 mm thick must be
introduced between the plate itself and the boiler.
Make
sure that the combustion head penetrates into the
combustion chamber to the extent requested by the
boiler makers.
ELECTRICAL CONNECTIONS
It is advisable to effect all electrical connections with
flexible electrical wire. Electrical lines must be kept away
from hot parts. Make sure that the power line to which
you intend to connect the unit is of voltage and frequency
suitable for the burner. Make sure that the main power
line, the relative fuse-equipped switch (indispensable)
and any limiter are able to withstand the maximum cur-
rent absorbed by the burner. For details see the specific
wiring diagrams for each individual burner.
FUEL FEED SYSTEM (LIGHT OIL)
The burner pump should receive fuel from a feed circuit which has an
ancillary pump and, in some cases, a pressure regulator capable of
modifying the pressure value 0,2 to 1 bar (see drawing 0002901120).
In this case, the value of the fuel feed pressure at the burner pump
(0,2 ÷ 1 bar) should not vary when the burner is at a standstill or
when it is operating at the maximum fuel delivery required by the
boiler.Normallyitispossibletorealizeacircuitwithoutapressure
