DESCRIPTION OF Series GI 1000 INDUSTRIAL BURNERS
The GI 1000 burner is a packaged version made up of separately supplied units; these components must be con-
nected at the burner installation site in full observance 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) version 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 modulation 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 burner is fitted with a device that automatically varies 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 internal 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 current absorbed by the burner.
For details see the specific wiring diagrams for each individual burner.
