Abstract
Official abstract text for this publication.
The invention is directed to a method for reducing NOx emission from an industrial process furnace comprising a firebox containing a burner and a tube, which method comprises subjecting an oxidant gas and/or a fuel gas ( 1 ) to humidification, thereby obtaining a humidified gas; and pre-heating the humidified gas with an external waste heat stream ( 20 ) before feeding the gas to the burner.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for reducing NO x , emission from a process furnace comprising a firebox containing a burner and a tube, the method comprising: subjecting an oxidant gas and/or a fuel gas to humidification, thereby obtaining a humidified gas; and superheating the humidified gas with an external waste heat stream and thereafter feeding the superheated, humidified gas to the burner, wherein the external waste heat stream has a temperature in the range of 40-1…
