COMBUSTION HEAD

Meku and MAN’s seem to be the only ones technologiesable 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.

Weishaupt is not a LOW NOx burner

BG does not match the new RAL UZ9; BGK has someproblems on commercial boilers

COMBUSTION HEAD: better than Meku

Increasing the flexibility of application (few models)

Reducing the resistance

Doing something different to be out of the patent

Reliable operation mode

Same or lower emissions

Riello design: air staging

An adjustable external re-circulation

keeps low the NOx emissionsFrom the middle

‘swirl’

Around the ‘airnozzle’ (adjustable)

Four small pipesto decrease the resistance

end to complete the combustion
