Abstract
A flow divider for use in a gas burner assembly supported in an opening in a furnace wall has injected fluid, such as gas and/or air, flowing through an inner burner pipe then outwardly through a plurality of openings for burning along the surface of a wall thus providing a near uniform radiant heat energy to the furnace. The flow divider has a plurality of nested members and a plurality of in-line members to divide the flowing gas and/or air to improve distribution and to promote more uniform mixing of the gas and air.
Claims24
A burner apparatus for furnaces comprising:
- a burner pipe having a side wall, a distal end portion, and a plurality of lateral openings in said side wall around said distal end portion;
- a flow divider comprising at least three in-line members within said burner pipe forming at least three longitudinal flow sections;
- a gas fuel intake in said burner pipe upstream of said flow divider;
- and
- an air intake in said burner pipe upstream of said flow divider such that gas fuel from said gas fuel intake and air from said air intake will form a fuel and air fluid stream which will flow through said longitudinal flow sections of said flow divider and out of said lateral openings.
A burner apparatus for furnaces comprising:
- a burner pipe having a side wall, a distal end portion, and a plurality of lateral openings through said side wall in said distal end portion;
- a flow divider comprising a plurality of nested members within said burner pipe;
- a gas fuel intake in said burner pipe upstream of said flow divider;
- and
- an air intake in said burner pipe upstream of said flow divider such that gas fuel from said gas fuel intake and air from such air intake will form a fuel and air fluid stream which will flow through said flow divider and out of said lateral openings,
- wherein said plurality of nested members include at least an inner member and an outer member such that said inner member is positioned within said outer member, a longitudinal core flow passage for said fuel and air fluid stream is provided through said inner member, a longitudinal annular flow space for said fuel and air fluid stream is provided between said outer member and said side wall, and at least one longitudinal intermediate flow space for said fuel and air fluid stream is provided between said inner member and said outer member.
A burner apparatus for furnaces comprising:
- a burner pipe having a side wall, a distal end portion, and a plurality of lateral openings through said side wall in said distal end portion;
- a flow divider within said burner pipe;
- a gas fuel intake in said burner pipe upstream of said flow divider;
- and
- an air intake in said burner pipe upstream of said flow divider such that gas fuel from said gas fuel intake and air from said air intake will form a fuel and air fluid stream which will flow through said flow divider and out of said late openings,
- wherein said flow divider comprises a plurality of nested members including at least an outer member positioned within said side wall of said burner pipe and an innermost member positioned within said outer member such that a longitudinal core flow passage for said fuel and air fluid stream is provided though said innermost member, a longitudinal annular flow space for said fuel and air fluid stream is provided between said outer member and said side wall, and at least one longitudinal intermediate flow space for said fuel and air fluid stream is provided between said innermost member and said outer member, and
- a plurality of in-line members which divide at least said core flow passage into at least three parts.
