Abstract
A gas burner assembly for a cooktop appliance including an upper chamber, a first plurality of burner ports, a lower chamber and a second plurality of burner ports. A first fuel-gas injector is configured to direct a first stream of fuel gas into the upper chamber, thereby drawing surrounding air to yield injection of a first mixture of fuel gas and air into the upper chamber. A second fuel-gas injector directs a second stream of fuel gas into a secondary opening that communicates with the lower chamber, thereby drawing surrounding air to yield injection of a second mixture of fuel gas and air into the lower chamber. The upper chamber being isolated from the lower chamber so that the first mixture of fuel gas and air in the upper chamber does not mix with the second mixture of fuel gas and air in the lower chamber.
