Abstract

A system comprises a counter-current injection device according to some embodiments. The counter-current injection device comprises fuel-air injection devices (50, 150) which are provided with fuel and air passages open to fuel and air injection orifices (70, 72, 156, 157, 210, 211), wherein the fuel and air injection orifices (70, 72, 156, 157, 210, 211) are arranged at the position deviated from center and opposite to an approximately longitudinal flow axis of an gas-turbine burner (30) in the approximate counter-current direction.

Description

Background technique [0001] It is hoped in this section to introduce the reader to various aspects of art that may be related to aspects of the present invention that are described and / or claimed below. It is believed that this discussion helps to provide the reader with background information to better understand the various aspects of the present invention. Accordingly, these statements should be read with the understanding that they are written in light of this point, and not as admissions of prior art. [0002] Combustion machines, such as gas turbines, produce various polluting emissions. For example, polluting emissions typically include carbon oxides (COx), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM). These polluting emissions are strictly regulated in the United States and elsewhere. NOx from gas turbines can be reduced by premixing fuel and air. Unfortunately, premixing produces an unstable flame that is difficult to stop, and the best ...
