WORK CURVES
Reference parameters for choosing blown air gas burners.
Blown air gas burners can be installed on both pressurised and vacuum boilers. It is essential to always refer to
the flow-pressure working curve as burner flow (expressed in kW) remains strongly linked to the pressure present
in the combustion chamber.
U
M
Example:
Boiler: power to hearth = 1400 kW and
pressure in combustion chamber = 3.0
mbar.
The meeting point between the straight
lines of combustion chamber pressure
and power to the hearth must fall within
the operating range of the boiler (see
example image).
