Refinery and petrochemical units, as critical pillars of the energy and chemical industries, depend heavily on thermal systems, particularly burners. Fired heaters are used to
Boilers serve as fundamental components in heating systems, supplying the thermal energy essential for a range of industrial and commercial applications. The burner, as the
In today’s world, energy conservation reducing environmental pollution are top priorities across various industrial sectors. Burners, as the central components of industrial furnaces and boilers,
NOx gases play an important role in the formation of smog, producing the brown haze often observed over cities, particularly during the summer. When exposed to UV rays in sunlight, NOx molecules break apart and form ozone (O3). The problem is made worse by the presence in the atmosphere of volatile organic compounds (VOC), which also interact with NOx to form dangerous molecules. Ozone at the ground level is a serious pollutant, unlike the protective ozone layer much higher up in the stratosphere. Nitrogen oxides form when oxygen and nitrogen from the air interact during a high-temperature combustion event. The heating industry and industrial burners, in particular, produce large amounts of nitrogen oxides.
The idea of Low NOx burners is to control fuel and air mixing at each burner in order to create larger and more branched flames. Peak flame temperature is thereby reduced, and results in less NOx formation. The improved flame structure also reduces the amount of oxygen available in the hottest part of the flame thus improving burner efficiency.
