This gas turbine equipment comprises a gas turbine and a control device. A combustor of the gas turbine uses ammonia as fuel, and uses the RQL method. A compressor of the gas turbine includes an intake adjustor that adjusts an intake rate which is the flow rate of air that flows into a compressor casing. When the concentration of NOx in exhaust gas reaches or exceeds a predetermined value, the control device controls the operation of the intake adjustor so that the intake rate decreases.

Gas turbine equipment with compressor airflow control responsive to NOx concentration and control method thereof

A control device is a control device for a gas turbine including a plurality of combustors and is configured to select combustors to ignite in accordance with a target load on the basis of a predictor which defines a relationship between a load and the number and arrangement of combustors to ignite and a combustion temperature.

Control device, gas turbine, control method, and program

A combustor includes: a first cylindrical body which is configured to hold a fuel nozzle extending in an axial line direction and through which air flows toward a downstream side thereof; a second cylindrical body that is connected to a downstream side of the first cylindrical body; and an outer shell that has an inner peripheral surface configured to define an air introduction channel through which air is introduced such that the air reverses course at an upstream end of the first cylindrical body and flows toward the downstream side together with an outer peripheral surface of the first cylindrical body. The inner peripheral surface has an outside narrowing surface that is formed to extend inward in a radial direction toward the upstream end of the first cylindrical body.

Combustor, gas turbine

A gas turbine combustor that mixes fuel with compressed air guided from a compressor to burn the fuel mixed with the compressed air to generate a combustion gas and supplies the generated combustion gas to a turbine is provided with: an inner cylinder forming a combustion chamber thereinside; an outer cylinder that covers the inner cylinder and forms, between the outer cylinder and the inner cylinder, a cylindrical outer peripheral flow path through which the compressed air flows; an end cover closing the end of the outer cylinder on an opposite side from a side the turbine is located; and a turn guide provided at the end on the end cover side of the inner cylinder, protruding from the outer peripheral surface of the inner cylinder toward the outer cylinder and smoothly connected to the inner peripheral surface of the inner cylinder.
