Abstract

There are provided an injector and an associated method for injecting and mixing gases, comprising a carbonaceous fuel and oxygen, in a combustion chamber of a combustion device. The injector has jets, which can be used to separately inject different combustion fuels. The injector is compatible with combustion devices that inject only gases, for example, a reheater that provides initial combustion in a power generation cycle or a reheater that recombusts a discharged gas from a gas generator and turbine. Further, the injector defines an annular space through which a recycle gas can be injected into the combustion chamber to lower the combustion temperature.

Description

technical field [0001] The present invention relates generally to apparatus and methods for injecting fluids, and more particularly, to an injector and associated method for injecting combustible fluids into a combustion chamber. Background technique [0002] Combustion of carbon-based compounds, or carbon-containing fuels, is widely used to generate power and electricity. In a typical power generation system, a carbonaceous fuel such as natural gas is mixed with an oxidant and burned in a combustion device called a gas generator. The resulting combusted gases are exhausted into a turbine that is mechanically coupled to a generator, causing the turbine to spin. The combusted gases are then discharged into one or more additional combustion devices called regenerators, where they are mixed with additional fuel and / or oxidant for subsequent combustion. The regenerator, which develops a pressure typically lower than that produced by the gas generator, discharges the regenerate...
