Calories rise suppression method of the gas gas turbine equipment, and low-calorie gas supply facilities

摘要

And to provide a low calorie supply equipment can be supplied as a gas turbine fuel to a stable by suppressing the surge in the calorie and low calorie. And supplies the low calorie gas supply pipe to the gas turbine 2 and the low calorie gas and (3), the low calorie gas supply pipe supplies gas supply pipe and exhaust gas (3) and (4), the low calorie gas supply pipe exhaust gas supply pipe (3) ( Calorimeter detects disposed in (3) the first mixer which is arranged in the connecting portion 4) and (6), the low calorie gas supply pipe, the heating value of the gas (11), the low calorie gas supply It is equipped with oxygen concentration meter (15) placed on the downstream side of the first mixer (3) and (6) the piping, the control unit (100), the controller (100), the calorimeter (11) supplying a exhaust gas feed pipe (4) when the detected value of exceeds the reference value, on the basis of the detection result of the oxygen concentration meter (15), so that the exhaust gas mixture ratio does not enter the flammability limit of the low calorie gas I want to control to.
