Abstract
Abstract A FLAME STABILIZER COMPRISES AN ANGLE SECTION FIXED WITH ITS APEX POINTING UPSTREAM. AT EACH OF ITS DOWNSTREAM EXTREMITIES IS A BIMETALLIC PLATE, THE TWO PLATES EXTENDING DOWNSTREAM IN THE DIRECTION OF FLOW AND PARALLEL TO EACH OTHER. A PILOT BURNER IN THE FORM OF A FUEL SPRAY BAR EXTENDS TRANSVERSELY OF THE STABILIZER WITHIN THE ANGLE SECTION IN WHICH THERE ARE SMALL HOLES TO ADMIT AIR TO THE BURNER. THE INNER FACES OF THE BIMETALLIC PLATES ARE OF NICKEL ALLOY HAVING A HIGH COEFFICIENT OF EXPANSION AND THE OUTER FACES ARE OF A REFRACTORY METAL SUCH AS NIOBIUM OR MOLYBDENUM HAVING A LOW COEFFICIENT OF EXPANSIONS. THE DIFFERENTIAL EXPANSION OF THE PLATES UNDER THE EFFECT OF HEAT CAUSES THESE TO BEND OUTWARDLY TO INCREASE THE FRONTAL AREA OF THE STABILIZER AND CAUSE INCREASED TURBULENCE.
