Abstract
Gas burners, of the type employing atmospheric injection of combustion air and having a throat defining an inlet or mixing area and a plurality of burner ports defining an outlet area, particularly gas inspirators of the type having a plurality of peripheral orifices, so as to introduce pressurized gas into contact with atmospheric are. The inspirator is characterized both by the economic method of its construction, as well as its capability of adjustment to inspirate different types of fuels. In one embodiment, the inspirator conduit is axially adjustable with respect to the burner mixing throat, so as to regulate the injection of gas and mixing of gas with air prior to combustion. The inspirator in its multi-fuel mode has a plurality of series of axially spaced orifices, additional series being opened upon axial extension of the inspirator into the mixing throat.
