<p><P>PROBLEM TO BE SOLVED: To provide a gas flow rate controller for common use for a plurality of different kinds of gases with a wide variety of calorific values without the need of exchanging a gas flow rate control plate located inside even when changing the kind of the gas to be supplied and a burner nozzle. <P>SOLUTION: Gas volume adjustment grooves 60 are formed on one side of the flow rate control plate 6, and a slide closer 7 is provided for putting a lid on the one side of the flow rate control plate 6 with the gas volume adjustment grooves 60 formed thereon. By changing the relative positions of the flow rate control plate 6 with respect to the slide closer 7, the area of a portion lidded by the slide closer 7 in the gas volume adjustment grooves 60 changes resulting in a change in a passage resistance of a gas passage so as to adjust a gas flow rate per unit time. Thus, the passage resistance of the gas passage increases continuously as the area of the lidded portion in the gas volume adjustment grooves 60 increases. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
