A direct-fired steam generator utilizes dual regulators for delivering combustible gas to a burner chamber. A first regulator is a constant pressure gas regulator. A second regulator is a variable pressure gas regulator. The variable pressure gas regulator utilizes a pressure feedback which is representative of the pressure in the burner chamber. One or more air blowers can be utilized to supply air (oxygen) to the burner chamber.
