NOx LOW NOx RADIANT WALL BURNE

摘要

Abstract: the present invention relates to the structure of the nozzle burner is low NOx low NOx burner nozzle assembly wall to the burning radiant tube burner includes radiant wall burner burner tube hollow Mmtwl Wfwht discharge discharge nozzle. The tube of the torch conduit stream to provide mixture fuel fuel air mixture to the combustion combustion area irradiated in the combustible range combustion zone takes the structure of the nozzle nozzle assembly.The discharge nozzle to the tube at a lower stream next to the radiant combustion area and adapted to guide the fuel air mixture to the combustion sources and a half radial direction substantially. The nozzle discharges of several members and guiding the flow of the flow directing members sorted in a row are circumferentially extends about the nozzle arranged to discharge these members identified several pathways passageways stretch in a a half s Soft overall.The passages so as to obtain different flow areas. The nozzle discharges as well end cowl terminal cap preventing axial flow of the mixture of air and fuel preparation.The terminal Llqlnswt hole hole extends axially and including combination nozzle burner fuel nozzle movable stages staged fuel arranged so that sticks of the central through hole of the such an EL The fuel was transferred in stages to the combustion range, which is far from the radiant combustion area.
