Abstract

QUEMADOR DE COMBUSTIBLE LIQUIDO O GASEOSO QUE COMPRENDE UN CONDUCTO (16) DE ALIMENTACION DE AIRE PRIMARIO, MEDIOS DE INYECCION (20, 21) DEL COMBUSTIBLE EN UN HOGAR (12) DISPUESTOS EN EL INTERIOR DE DICHO CONDUCTO, EN EL EJE DE ESTE ULTIMO, Y QUE LLEVA ORIFICIOS MULTIPLES QUE CREAN VARIAS LLAMAS DIVERGENTES E INDEPENDIENTES EN EL HOGAR, UN ESTABILIZADOR DE LLAMAS (22) DISPUESTO COAXIALMENTE EN EL INTERIOR DE DICHO CONDUCTO, Y VARIOS CONDUCTOS DE ALIMENTACION (28,29) DE AIRE SECUNDARIO DISPUESTOS ALREDEDOR DE LOS MEDIOS DE INYECCION DE COMBUSTIBLE Y DEL CONDUCTO DE AIRE PRIMARIO EN POSICIONES TALES QUE CADA CONDUCTO DE AIRE SECUNDARIO PROPORCIONA UN FLUJO ADICIONAL A CADA LLAMA TRAS UNA PRIMERA FASE DE COMBUSTION. ESTE QUEMADOR SE CARACTERIZA PORQUE LLEVA UN ANILLO DE MATERIAL REFRACTARIO (24) QUE RODEA EL EXTREMO DELANTERO DEL CONDUCTO DE AIRE PRIMARIO (16), PORQUE DICHO ANILLO LLEVA SOBRE SU CARA DELANTERA UNA CAVIDAD EN FORMA DE CUBETA (25) CUYO FONDO ES PRACTICAMENTE PLANO, PORQUE DICHO CONDUCTO DE AIRE PRIMARIO DESEMBOCA EN EL FONDO DE DICHA CAVIDAD Y PORQUE DICHOS CONDUCTOS DE AIRE SECUNDARIO ESTAN CONSTITUIDO POR PASOS (28) FORMADOS EN DICHO ANILLO Y QUE DESEMBOCAN SOBRE LA CARA DELANTERA DE LA PARTE (30) DEL ANILLO QUE BORDEA DICHA CAVIDAD.LIQUID OR GASEOUS FUEL BURNER THAT INCLUDES A PRIMARY AIR FEEDING DUCT (16), INJECTION MEANS (20, 21) OF THE FUEL IN A HOME (12) INSIDE THE SUCH CONDUCT, AT THE LAST AXIS, AND THAT IT CARRIES MULTIPLE ORIFICES THAT CREATE VARIOUS DIVERGENT AND INDEPENDENT CALLS IN THE HOME, A CALL STABILIZER (22) COAXIALLY PROVIDED INSIDE THE SUCH CONDUCT, AND VARIOUS FEEDING CONDUCTES (28,29) THROUGH THE MIDDLE SECONDARY FOR FUEL INJECTION AND PRIMARY AIR CONDUCT IN SUCH POSITIONS THAT EACH SECONDARY AIR CONDUCT PROVIDES AN ADDITIONAL FLOW TO EACH CALL AFTER A FIRST COMBUSTION PHASE. THIS BURNER IS CHARACTERIZED BECAUSE IT CARRIES A RING OF REFRACTORY MATERIAL (24) THAT SURROVES THE FRONT END OF THE PRIMARY AIR CONDUCT (16), BECAUSE SUCH RING TAKES ON HIS FRONT FACE A CAVITY IN THE FORM OF A CUBETTE (25) WHOSE FUND IS THE FUND , BECAUSE SUCH PRIMARY AIR CONDUCT WAS DISCHARGED IN THE FUND FOR SUCH CAVITY AND BECAUSE THESE SECONDARY AIR CONDUCTS ARE CONSTITUTED BY STEPS (28) FORMED IN THE SUCH RING AND UNPACKING ON THE FRONT SIDE OF PART (30) OF THE RING THAT EMBROIDERED CAVITY.
