COMBUSTION HEAD
 Weishaupt is not a LOW NOx burner
 BG does not match the new RAL UZ9; BGK has some
problems on commercial boilers
 Meku and MAN’s seem to be the only ones technologies
able to achieve RAL UZ 9 performances;
 MAN’s head has high resistence
 Meku has high resistance too; moreover
there is a patent (high cost) and some problems
on ‘cold’ startings. No flexibility.

3. COMBUSTION HEAD: better than Meku
2nd step: Definition of the required features target: ‘how to be the best’
COMBUSTION HEAD: better than Meku
 Same or lower emissions
 Reducing the resistance
 Doing something different to be out of the patent
 Increasing the flexibility of application (few models)
 Reliable operation mode

COMBUSTION HEAD: result
An adjustable
external re-circulation
keeps low the NOx emissions
Riello design: air staging
Four small pipes
to decrease the resistance
end to complete the combustion
Around the ‘air
nozzle’ (adjustable)
From the middle
‘swirl’
