Limpsfield burners provide high turndowns typically between 4:1 and 10:1. This
turn down is established by using a split gas head or a spider head. The split gas
head can be used on most applications and provides excellent mixing to maintain
good combustion throughout the firing range.
The unique spider head assembly offers the user high turn down ratios. It was
initially designed to be fired when using fuels with high burning velocities such as
Propane or Hydrogen. Unlike the split head, the fuel is introduced after the diffuser
plate enabling the flame to establish good retention whilst maintaining excellent
mixing.
Limpsfield will design and engineer the correct solution to suit your application.
An example of Limpsfield's in-depth engineering capabilities;
This spider head assembly was for an application where Hydrogen was produced
on-site as a bi-product of a chemical reaction. The heads construction is
such that the fuels are supplied from two individual gas trains
to separate gas controlvalves, one on either
side of the burner. The diffuser view shows
two different sizes of main injector, these
are used in order to accommodate the
differences in the flame velocity of hydrogen
and propane.

Limpsfield burners have been designed to ensure minimal emissions are released
into the atmosphere. This means less harmful emissions are created, but also
means greater e ciency of the burner due to good combustion which in turn
creates great fuel savings. Typically Limpsfield burners operate at <3% O2 and
<10ppm of CO. These figures continue throughout the firing range, from low fire to
high fire.
