F23D14/00—Burners for combustion of a gas, e.g. of a gas stored under pressure as a liquid
F23D14/02—Premix gas burners, i.e. in which gaseous fuel is mixed with combustion air upstream of the combustion zone
F23D14/04—Premix gas burners, i.e. in which gaseous fuel is mixed with combustion air upstream of the combustion zone induction type, e.g. Bunsen burner
F23D14/10—Premix gas burners, i.e. in which gaseous fuel is mixed with combustion air upstream of the combustion zone induction type, e.g. Bunsen burner with elongated tubular burner head
Foyer primaire additionnel rayonnant, introduit dans le foyer d'origine des chaudieres, pour ameliorer la combustion et diminuer, dans les rejets atmospheriques, la proportion d'elements polluants
