Abstract (en)

[origin: WO2021160506A1] A boiler (2) is provided with a mixer (4) to mix together fuel and oxidiser, and a burner (6) to burn a mixture of fuel and oxidiser from the mixer (4). The mixer (4) has a plurality of venturis (8,10) and a mixing flow pathway (12) extending from the plurality of venturis (8,10). The mixing flow pathway (12) is configured to provide fluid communication between the plurality of venturis (8,10) and the burner (6). Each venturi (8,10) has a mixing chamber (14), a fuel inlet (16) to provide fluid communication between the mixing chamber (14) and a source of fuel (18), an oxidiser inlet (20) to provide fluid communication between the mixing chamber (14) and a source of oxidiser (22), and a venturi outlet (24) to provide fluid communication between the mixing chamber (14) and the mixing flow pathway (12). The venturi outlets (24) open into the mixing flow pathway (12).
