The present disclosure relates to the computer technology and provides a method and a device for selecting a cache line to be replaced, and a storage medium. In the present disclosure, a blocking state binary tree is added to replace a replacement state binary tree, and a cache line to be replaced is selected based on the blocking state binary tree and a usage state binary tree, such that the earliest cache line, acting as the cache line to be replaced, can be accurately selected from the replaceable cache lines in a blocking cache.

Method and device for selecting cache line to be replaced, and storage medium

A fuel supply system is provided having a first fuel gas compressor configured to be driven by a motor and a second fuel gas compressor configured to be driven by a shaft of a gas turbine system. The first fuel gas compressor and the second fuel gas compressor are configured to supply a pressurized fuel flow to a combustor of the gas turbine system, and the first fuel gas compressor and the second fuel gas compressor are coupled to one another in series.

Fuel supply system

A fuel nozzle system for enabling a gas turbine to start and operate on low-Btu fuel includes a primary tip having primary fuel orifices and a primary fuel passage in fluid communication with the primary fuel orifices, and a fuel circuit capable of controlling flow rates of a first and second low-Btu fuel gases flowing into the fuel nozzle. The system is capable of operating at an ignition status, in which at least the first low-Btu fuel gas is fed to the primary fuel orifices and ignited to start the gas turbine, and a baseload status, in which at least the second low-Btu fuel gas is fired at baseload. The low-Btu fuel gas ignited at the ignition status has a content of the first low-Btu fuel gas higher than that of the low-Btu fuel gas fired at the baseload status. Methods for using the system are also provided.

Nozzle system and method for starting and operating gas turbines on low-Btu fuels

In a first embodiment, a system, including an exhaust duct configured to flow an exhaust gas, and an air injection system coupled to the exhaust duct, wherein the air injection system comprises a first air injector configured to inject air into the exhaust duct to assist flow of the exhaust gas through the exhaust duct.

System and method for reducing back pressure in a gas turbine system

A system including a fuel-supply system including, an auxiliary-fuel-gas compressor configured to compress a fuel for use by a gas-turbine system, an expander configured to generate power by expanding an oxidant from the gas-turbine system, and a motor/generator configured to function in a motor mode and in a generator mode, wherein the motor/generator drives fuel compression with the auxiliary fuel-gas compressor in the motor mode, and the motor/generator generates power in the generator mode as the expander uses oxidant from the gas-turbine system to drive the motor/generator.

System and method for operating a power plant

A system includes a cooler configured to cool a first gas portion of a compressed gas fuel and discharge a cooled fluid. The cooled fluid comprises a cooled gas portion and a cooled liquid portion. The system also includes a separator configured to separate the cooled fluid into the cooled gas portion and the cooled liquid portion and a mixing tank configured to mix a second gas portion of the compressed gas fuel with the cooled gas portion in direct contact with one another to produce a superheated gas fuel. The superheated gas fuel comprises a degree of superheat above a lower threshold for a combustion system.
