Version NR (NOx reduced)
Description

Weishaupt industrial burners, sizes 30 to 70, have been especially designed for
industrial capacity ranges. The monobloc burners are noteworthy for their large
capacity and operational ranges and numerous other interesting details:

• Compliance with the most stringent directives and emission limits

• Large capacity and operational ranges
• Stable fan reference line - good combustion behaviour
• Quiet operation
• Burner housing can be hinged open
• Easy to install, set and service
• Automatic air shut off on burner shut down

to reduce operational noise considerably.

The forward and reverse movements of

ensure that that the air annulus is correct
at every load point throughout the
capacity range. This results in optimum
velocities over the whole of the regulation
range. With this system, the mixing
pressure is increased at partial load,
improving the intermixture of fuel and air. Control range up to 1:5
This results in a reduction in excess air
and improved combustion efficiency due
to the constant air/fuel ratio.

Installation example

Low pressure supply: flanged valve train with DMV valves Single solenoid valves

The installation example shows a basic valve train, i.e. DMV

solenoid valves and additional gas valve train components.

Layout of the valve train

On boilers with hinged doors, the valve train must be mounted on
the opposite side to the boiler door hinges. The pilot line solenoid
valve can be fitted to either side.

Compensator
To enable a tension free mounting of the valve train, it is
recommended that a compensator is also fitted.

Break points in the valve train

Break points in the gas line should be provided to enable the
door of the heat exchanger to be swung open. The main gas line
is best separated at the compensator.

Support of the valve train

High pressure supply: flanged valve train with DMV valves
The valve train should be properly supported in accordance with
the site conditions. See the Weishaupt Accessories List for
various valve train support components.

Gas meter
A gas meter must be installed to measure gas consumption
during commissioning.
