gas power burners consist of the following main component groups:
•
Fan housing
•
Burner housing
•
Mixing manifold
•
Flame tube
•
Gas ramp with safety devices
•
Electrics (wire connections on the burner)
The patented burner system offers excellent results in terms of burner capacity, burner safety, start-up be-
haviour, burner adjustment and hygiene behaviour.
4.1
The mixing manifold
The mixing manifold represents the central burner unit in terms of function. Combustion air is suctioned
from the burner environment via a combustion air blower with 230/400V drive motor and blower impeller.
The compressed air flow is fed axially to the burner body and the gas/air mixing manifold.
