Abstract

A BOILER STRUCTURE CAPABLE OF EFFICIENTLY ALLEVIATING OR PREVENTING CORROSION AND SLAGGING ON FURNACE WALLS IN A FURNACE IS PROVIDED. A CIRCULATING FIRING BOILER STRUCTURE IS CONFIGURED SO THAT FUEL AND COMBUSTION AIR SUPPLIED INTO A FURNACE (11) FROM BURNERS (12) DISPOSED AT A PLURALITY OF POSITIONS ON FURNACE WALLS (11A) FORMING A RECTANGULAR CROSS SECTION ARE COMBUSTED SO AS TO FORM A SWIRLING FLOW. AIR SUPPLYING PARTS (20) ARE DISPOSED NEAR FLAME-AFFECTED PORTIONS OF FURNACE WALL SURFACES, WHERE FLAMES FORMED BY THE RESPECTIVE BURNERS (12) APPROACH OR CONTACT, TO FORM REGIONS HAVING A HIGHER AIR CONCENTRATION THAN THE PERIPHERIES THEREOF.
