KBSA™
Steam atomizing oil burner
for diesel oil and heavy fuel oil
KBSA 600 – KBSA 4200
________________________________________________________________________________________
General:
The KBSA steam atomizing burner
is designed for use on our top- and
side-fired boilers and can be delivered
premounted. The use of oil
flowmeter and modulation of the
atomizing steam pressure ensures
a stable combustion at all loads,
also in the lower end. All burner
mountings are arranged to ensure
easy installation and maintenance.
| Capacity range: |
1.7 – 46.9 MW |
Description:
The KBSA steam atomizing burner has
been designed to meet customer requirements
such as high turndown
ratio, minimum installation and operation
costs, and the capability to deliver
inert gas at low loads.
Two swirlers produce a mixture of air
and fuel close to the stoichiometric
value. As a result, low excess air ratio
during combustion and low oxygen content
in the exhaust gas provide good
economy. For maintenance and inspection
purposes, the air register is retractable
from the windbox.
Automatic shut-off valves, re-circulation
valve, solenoid valves, needle valves,
and other necessary burner components
are fitted on the windbox. Standard ball
valves are used throughout with electric/pneumatic actuators on the automatic
valves. A water and steam separator
is incorporated to achieve a suitable,
dry atomising steam quality.
Flexible hoses connect the valve
arrangement and burner lance on the
oil side and on the atomizing steam
side. Safe ignition of the burner is
ensured by means of the diesel ignition
burner which is equipped with its own
ignition transformer, oil pump and
nozzle. During operation of the main
burner, the ignition burner is purged
with air in order to prevent coke formation
on the nozzle and electrodes.
