BURNER HAVING EXTERIOR WOVEN LAYER

摘要

A burner apparatus (28) includes a mounting head (28) having a fuel inlet opening (116) defined in the mounting head for receiving combustion air and fuel gas through the opening. An inner support structure (136) is attached to the mounting head. The inner support structure defines an interior zone (138) communicated with the fuel inlet opening of the head. An exterior layer (140) of flexible woven heat resistant material is received about the inner support structure and defines an exterior flame attachment surface (142). The mounting head may include a radial opening (124) defined therethrough. An igniter (135) is located outside of the mounting head adjacent the radial opening so that the igniter is proximally spaced from a combustion zone surrounding the burner apparatus. The burner apparatus may include a plurality of forminous back pressure plates (160, 162, 164) located in the interior zone distal of the igniter for balancing the pressure of the fuel gas/combustion air mixture along the length of the burner.
