Weishaupt WK-series burners have
been designed especially for
industrial use. The modular design
of the burners, coupled with their
large capacity range, makes them
ideally suited to a broad spectrum
of special applications.
heat exchanger in the flue can be used
to reclaim a large amount of energy
from these hot flue gases, increasing
efficiency by up to 10 %. Weishaupt
WK-series industrial burners can be
operated with preheated combustionair temperatures of up to 250 °C.
Modular principle
Weishaupt WK-series industrial burners
are of modular design. That means the
fan, pump station, and preheater station
are all selected independently of the
burner. This concept offers a high
degree of flexibility in matching to the
most diverse applications.
Nozzle-head shut-off device
At burner shutdown, or when changing
over to gas operation, a safety shut-off
device located in the oil atomising
system shuts off the oil flow directly in
the nozzle orifice, preventing the
escape of any oil.
Digital combustion management
Digital combustion management
ensures the simple and safe operation
of combustion plant. Emissions are
minimised and economy is maximised.
Insulated burner housing
The burner housing is fitted with internal
insulation (optional extra on the ambientair versions of the WK 40 and 50). This
significantly reduces the surface
temperature of the housing during
operation with preheated combustion
air. The insulation also provides effective
noise reduction.
Heat recovery using preheated
combustion air
Many industrial processes create high
flue-gas temperatures due to the high
temperature of the medium used. A
2
Modulating operation
Within its operating range, the burner’s
output is matched to the current heat
demand.
Reduced capacity at start-up
The burners start at gas operation at a
reduced ignition load (WK (G) MS
> 17.5 MW with an additional pilot burner). This means that only a small quantity of gas flows into the combustion
chamber. After the ignition phase, the
burner drives to partial load.
Controlled shutdown from partial
load
Controlled shutdown of the burner
always takes place from the partial-load
position, thus preventing impact on the
gas main.

Digital combustion management:
Precise, simple, and reliable
Measures for saving energy and
increasing safety and reliability
Electronic compound regulation with
the W-FM 100 and 200 combustion
managers facilitates the extremely
precise, hysteresis-free setting of the
burner. The burner can be adjusted for
ideal combustion figures throughout its
entire capacity range. This reduces flue
gas losses and saves fuel.
Setting via the control and display unit
Variable speed drive reduces electrical
consumption and facilitates a soft start
of the combustion air fan. The use of
VSD also reduces noise emissions by a
considerable amount.
Digital combustion management
means optimal combustion figures,
continuously reproducible setpoints,
and ease of use.
O2 trim saves fuel through a continual
and extremely efficient optimisation of
the combustion air. Different O2 probes
are available, providing suitable solutions
for almost all fuels in applications with
flue-gas temperatures below 300 °C.
Combined CO/O2 control ensures an
ultimate degree of safety. CO emissions
are continually monitored and, if the
defined limit is exceeded, the burner is
operated with an increased amount of
excess air for a short period of time
before the O2 trim returns the burner to
its preset O2 setpoint. Should external
influences prevent a non-critical
condition from being reached, then the
burner will undergo a controlled shutdown.

Emissions reduced
by the multiflam® principle
Weishaupt’s multiflam® technology
was designed for gas and dual-fuel
burners. By using a patented 3LN
mixing head, NOx emissions on WKseries burners can be reduced to
extremely low levels.
Weishaupt has set an all-new benchmark, achieving levels below 80 mg/m3
on gas and 120 mg/m3 on oil, subject
to the combustion chamber geometry.

At the heart of Weishaupt’s multiflam®
technology is a special mixing-assembly
design which distributes the fuel among
primary and secondary nozzles. This
results in extremely efficient combustion
thanks to recirculation of the flue gases
directly at the mixing assembly.

Weishaupt’s multiflam® burners meet
the world’s toughest standards. In those
countries with particularly stringent
environmental legislation, such as
Switzerland, multiflam® industrial
burners are market-sector leaders.

Flame monitoring
for demanding safety requirements
burners firing from different directions
into a single combustion chamber, and
for process plant with various flame
sources. The W-FC assembly monitors
each flame separately via a loaddependent switching threshold for each
fuel. This guarantees a distinct
differentiation from extraneous sources.
The CFC3... flame sensor functions in
parallel with the QRA73 flame sensor on
the W-FM 200 combustion manager. This
convenient, load-dependent setting of
the on and off thresholds rests upon the
electronic VLoad module, which can be
configured using software.
Testing and optimisation using a software tool
Weishaupt Flame Control (W-FC) is a
reliable flame monitoring system
designed for demanding safety
requirements.
W-FC 4.0 is for plant with multiple
burners firing from the same direction
into a single combustion chamber. The
W-FC assembly utilises flame frequency
to monitor each flame separately via a
load-independent on and off threshold
for each fuel. The CFC3... flame sensor
functions in series with the QRA73 flame
sensor on the W-FM 100/200 combustion manager.
W-FC 6.0 is to monitor flame stability
on plant with flue-gas recirculation for
extreme NOx requirements. With this
version, the QRA73 flame sensor monitors
the flame while the CFC3... controls the
flue gas volume based on the stability of
the flame to ensure safe operating
conditions. In this way, reliability of operation with optimal emissions is achieved
under varying conditions. The VLoad
module enables a load-dependent switching threshold to be tailored to the operational situation.
W-FC 4.0
For classical parallel firing into a combustion
chamber, with a maximum turndown of 4:1
W-FC 5.0
For firing into a combustion chamber from
opposing directions, and individual/staged firing
of multiple burners
W-FC 5.0
All versions meet EN 298 continuous
operation requirements.
Note: If a turndown in excess of >1:4 or
single-burner operation is required, the
higher specification W-FC 5.0 must be
selected.
For plant with various flame sources, such as
waste and biomass incineration, process plant,
etc.

This variant facilitates reliable ignition

Flame monitoring is via a separate
ionisation probe, which necessitates the
use of a W-FM 200 combustion
manager.
An ignition electrode is used to ignite
the pilot burner’s gas mixture. The
pilot burner is then used to ignite the
main flame upon fuel release.
This reliable solution was developed
especially for heavy and special fuel
oils with widely varying characteristics.
It is also suitable for extreme ignitions,
such as cold-starting plant that utilises
pre-heated combustion air.

Layout of the valve train (vertical burner installation)
The “offset gas butterﬂy and solenoid valves” option is strongly recommended
because of the increased heat radiation due to the vertical boiler design and the
high temperatures of media such as thermal ﬂuid.
Note: This variant is not available with the SKP25 pressure regulator due to the
need for a stabilisation section.

The space between the combustion head and the refractory
should be filled with a resiliant, non-solid insulating material,
such as Cerafelt.
Maintenance-friendly combustion head:
On all burner versions, the standard-length combustion head can be inserted
and withdrawn through the service opening in the burner housing.

Overview of options, installation
positions, and weights
Vertically ﬁring Weishaupt burners have been
especially designed for use on vertical plant,
such as steam boilers, thermal ﬂuid heaters,
and process applications.
Vertical execution
l18
Reliable operation: Safety-critical components
such as the gas butterﬂy valve, stepping motor, gas
shut-off valves, and gas pressure switches, are
securely located away from high-temperature
zones to ensure their reliable operation. The offset
position of the gas pilot valve protects it from high
levels of radiant heat from the heat exchanger.
