An apparatus (1) for supplying a low calorie gas which comprises a low calorie gas supply piping (3) for supplying a gas to a gas turbine (2) as a fuel, a waste nitrogen supply piping (4) connected to a fuel gas supply tubing (3) for supplying a waste nitrogen generated in at least one (20) of an oxygen producing plant and a nitrogen producing plant to the low calorie gas supply piping (3), a calorie meter (11) provided in the low calorie gas supply piping (3) for measuring the heating value of the gas, and a controlling device (100), wherein the controlling device (100) controls so as for a waste nitrogen to be supplied though the waste nitrogen supply piping (4), when the measured value of the calorie meter (11) exceeds the standard value. The above apparatus for supplying a low calorie gas can be suitably used for suppressing the sharp rise in the calorie of a fuel gas and supplying the fuel gas as a stable fuel for a gas turbine. |
