摘要:
The invention relates to a gaseous fuel (including all mixtures thereof) burner structure, characterised in that it comprises: a housing defining a distal flame outlet end and a proximal gaseous fuel and air supply end, both ends having covers; a pressurised-air inlet arranged in the housing close to the proximal end, defining an inner pressurised-air-supply chamber; a pressurised-gaseous-fuel-supply duct arranged in the centre, housed in a first mixing chamber and provided with a plurality of openings for the outflow of the gaseous fuel to said first mixing chamber, said first mixing chamber also comprising a plurality of openings for supplying pressurised air axially and radially; an igniter arranged inside said first mixing chamber for a first combustion; a second, over-mixing chamber arranged colinearly with said first chamber, the end of the fuel duct comprising a cover provided with openings via which gaseous fuel is axially supplied to said second, over-mixing chamber, and the wall of said second chamber comprising openings via which pressurised air is radially supplied, where a second stage of the combustion process is carried out; and a third, conical flame-formation chamber colinearly connected to the end of said second, over-mixing chamber.
