Burner apparatus

A multiple burner assembly apparatus comprising:

• a burner assembly mounting plate, said burner assembly mounting plate having a generally centrally located opening and a plurality of additional openings laterally spaced from said centrally located opening and generally equally spaced from said centrally located opening and each other;
• a burner assembly disposed in each of said openings, each of said burner assemblies comprising:
• a burner assembly tube in surrounding relationship to said opening;
• a nozzle disposed in said burner assembly tube for introducing a combustible fuel and
• a burner assembly vane disposed in said burner assembly tube, said vane including a series of radially extending, circumferentially spaced slots.

a burner apparatus comprising:

• a housing defining a chamber and having an air inlet;
• a peripherally extending baffle disposed in said housing, a first peripherally extending flow passage being formed between said housing and said baffle, said first flow passage being in open communication with said air inlet;
• a peripherally extending combustion liner disposed inwardly of said baffle, a second peripherally extending flow passage being formed between said liner and said baffle, said second flow passage being in open communication with said first passage;
• a reversing diverter disposed in said chamber, said diverter being positioned to direct air flowing from said first flow passage into said second flow passage;
• a burner assembly mounting plate disposed in said liner, said burner mounting plate having a first side and a second side, said mounting plate and said liner at least partially defining a burner barrel on the first side of said mounting plate;
• at least one burner assembly mounted on said burner mounting plate;
• and
• a plenum on the second side of said mounting plate, and being in open communication with said second flow passage whereby any air flowing into said plenum from said second flow passage is heated by combustion gases formed in said burner barrel prior to entering said plenum, said baffle has at least one baffle perforation through said baffle providing open communication between said first flow passage and said second flow passage.
