Rapid energy release burners and methods for using the same

摘要

A burner having a high shape factor nozzle including a nozzle opening having a shape factor from about 10 to about 75, the shape factor being defined as the square of the nozzle perimeter divided by twice the nozzle cross-sectional area, and an annular nozzle surrounding the high shape factor nozzle, wherein the high shape factor nozzle is configured to be supplied with one of a fuel gas and an oxidizer gas, and the annular nozzle is configured to be supplied with the other of a fuel gas and an oxidizer gas. A method of rapid energy release combustion, including supplying a fuel gas and an oxidizer gas to a burner having a high shape factor nozzle and an annular nozzle surrounding the high shape factor nozzle.

1. A burner comprising:
a high shape factor nozzle including a nozzle body and nozzle opening having a shape factor from about 10 to about 75, the shape factor being defined as the square of the nozzle perimeter divided by twice the nozzle cross-sectional area; and an annular nozzle surrounding the high shape factor nozzle, wherein an annular nozzle opening is formed between the annular nozzle and the high shape factor nozzle; wherein the high shape factor nozzle is configured to be supplied with one of a fuel gas and an oxidizer gas, and the annular nozzle is configured to be supplied with the other of a fuel gas and an oxidizer gas; and wherein the high shape factor nozzle opening and the annular nozzle opening are sized so as to provide a velocity ratio of a gas stream flowing through the annular nozzle to a gas stream flowing through the high shape factor nozzle opening, VANNULAR/VHSF, from about 0.05 to about 0.9.
