GAS/HEAVY OIL KRBY2050 KRBY2060 KRBY2080 duemila SERIES

PNEUMATIC ATOMIZATION WITH ELECTRONIC OPERATION

with viscosity up to 4000 cSt at 50°C (530°E at 50°C)

This particular GAS/HEAVY OIL burners series has been developed in order to use
compressed air or, alternatively, steam as a fluid to atomize the fuel, with the
aim to achieve a better combustion result compared to the one
gained using the traditional atomizing systems.
These burners are provided with a low pressure nozzle which
allows consumption levels to be kept low and which also
limits the general wear of the whole atomization system.
All burners are progressive and are completed with an
electrical control cabinet and with a pump oil to be
installed by the final user. Furthermore, the nozzle performs
an automatic cleaning process at the end of each cycle.
The plant must be provided with compressed air or steam at
6-10 bar.
Burners are ignited through a pilot which can work either
with natural gas or LPG and are suitable to be used with
fuels with a viscosity up to 4.000 cSt at 50°C (530°E at
50°).
The standard version of burners is set up to atomize
with compressed air only; when steam is requested for the
atomization, the burner will be modified though a specific kit.
However, compressed air must be always present at the burner in the
following cases:
- cold start ups when no steam is available;
- valve opening for automatic nozzle cleaning.

Oil pump set (pump, motor, oil tank and filter) is included, but supplied loose (not assembled on the burner)

Attention: the graph shows the value of the gas output (kW) against the corresponding pressure without the combustion chamber back pressure. To know the
minimum gas pressure at gas train, in order to get the gas output, it is necessary to add the boiler back pressure to the value read on the curve.
