Information on monobloc industrial burners

WKmono-series industrial burners

WKmono 80 industrial burners • 1 200–17 000 kW
For more than six decades, Weishaupt burners have
proven themselves on a wide variety of heat generators
and process plant. Their success stems from a relentless
demand for high-quality materials and workmanship, and
uncompromising quality control standards.

Weishaupt continually establishes new benchmarks with its well-

engineered products, facilitated by the ever-constant efforts of
its own Research and Development Centre.

It was such efforts that enabled the rapid development of the

WKmono 80, which shares its platform with the duobloc WK 80
burner. The large 1 200 to 17 000 kW range of the WKmono 80,
which is available in NR and multiflam® versions and is suitable
for natural gas, LPG, and light oil, is particularly impressive.

All Weishaupt burners are manufactured at the company’s main

plant in Schwendi in southwestern Germany. Not only does this
extremely modern production facility serve as a beacon of safety,
precision, and cleanliness, it also allows for a rapid response
when assembling medium and large-sized burners, which are
almost always individually configured. The high proportion of
in-house production, among other things, allows Weishaupt to
meet its own demands for high levels of quality and to ensure
purpose-built items can be produced promptly.

Of course, Weishaupt’s product range also runs the gamut of

modern instrumentation and control equipment, including fully
comprehensive solutions for complex building automation projects.

Future-oriented, economical, flexible.

A rail system, for example, makes it
pump station
easy to withdraw and insert the mixing
assembly of the 80/2-size burner during
servicing. Tried-and-tested safety shutoff
devices, oil regulators, pump stations,
and other system components from the
WK burner range provide a high degree
of efficiency and flexibility. The standard
air inlet draws air from below, but is
optionally available in an inverted position
for sites with limited floor clearance.

The combustion managers are, in a nut-

shell, “digital reliability”. Their adaptability
and versatility leave nothing to be desired.
VSD, O2 trim and communication with
superordinate control systems are
commonplace features for equipment
of this size.

Since no one fuel is the same as the

next, different mixing assemblies have
been specially developed for use with
particular fuels. Reliable combustion
with a wide range of gases and oils is
thereby guaranteed.

This next generation of monobloc burner

shares in Weishaupt’s guiding principles
of cost-effectiveness, efficiency, and
reliability.

The sound-attenuated air inlet

can also be supplied inverted with
a connection flange for a ducted

Exceptions
Normally, valve train layouts LP1 and LP2 are used for gas flow pressures up to a maximum of 300 mbar. This allows for pressure losses between the transfer
station and the valve train. Furthermore, it is assumed that the transfer station utilises components (SSV, SRV, regulator) that are not of the highest class of accuracy.
In individual cases, following consideration and approval by Weishaupt’s headquarters, a gas flow pressure of up to 360 mbar can be approved if the appropriate
conditions exist.

Emissions reduced
by the multiflam® principle
The multiflam® principle developed
and patented by Weishaupt is an
innovative way of reducing NOx NOx
[mg/Nm3]
emissions from combustion plant to
a minimal level. 160

150
At the heart of Weishaupt’s multiflam®
technology lies a special mixing assembly 140
Medium Medium
design. Fuel is distributed among several 130 temperature temperature
nozzles and combusted in a primary 130–200 °C ≤ 130 °C
and a secondary flame. Temperature in 120
the flame’s core is considerably reduced, 110
resulting in an effective reduction of
nitrogen oxides. 100

90
The wide range of ratings across which
80
multiflam® burners are now available is
equally outstanding. All the way from 70
the WM 10 monarch® burner right up to
60
the WK 80 industrial burner, there is
now a multiflam® burner for outputs 50
ranging from 120 up to 23 000 kW.

Flexibility with flue gas recirculation

Where stringent emission limits for oxides
of nitrogen are in force, Weishaupt’s
multiflam® mixing assemblies for gas-
fired burners can be combined with flue
gas recirculation. Weishaupt takes
advantage of the special properties of
the flame geometry, and with it the
adaption to the combustion chamber, to
reduce NOx levels.

So ➞ High-pressure regulator for po ≤ 350 mbar.

* The LPG charts are based on propane, but may also be used for butane.

Stated flow pressures are based on a combustion chamber resistance Flanged

of 0 mbar. The combustion chamber pressure of the heat generator
must be added to the figure determined from the above chart when DN 100 DMV 5100/12
sizing the gas valve train. DN 125 VGD 40.125
DN 150 VGD 40.150
For low-pressure supplies, EN 88-compliant governors with safety diaphragms
are used.

For high-pressure supplies, an EN 334-compliant high-pressure regulator

should be selected from the following technical booklets:
• Regulators up to 4 bar, Print No. 83001202
• Regulators with safety devices, Print No. 83197902

Refer to the burner’s rating plate for the maximum connection pressure.
