Abstract
A gas mixing line burner having a stoichiometric turndown ratio in the range of between twenty-five and thirty to one and capable of operating at a capacity of about 2,000,000 BTU/HR per lineal foot of burner. The burner includes an air/fuel manifold having a discharge face which causes combustion air jets to mix with fuel jets and form a main combustible mixture which is provided with a constant ignition source by virtue of stabilizing air jets interacting with the fuel jets and creating a secondary combustible mixture down the center of the main mixture. One embodiment of the burner includes a combustion chamber which is formed by refractory material while the combustion chamber of an alternative embodiment is formed by stainless steel sections connected by expansion joints which prevent warpage of the sections.
