Some industrial processes produce synthesis and recovery gaseous streams which have, as main characteristics, high temperatures, low pressures and, most important, very low calorific values. BCE can design and supply Off Gas and Low LHV burners suitable to burn such gaseous streams, to recover the energy that otherwise would be lost.
These burners are supplied with external gas scroll, through which the gaseous stream is injected inside combustion chamber. Each burner is also supplied complete with gas lances and central gas gun, which are necessary to heat up the system before syngas injection.
Sometimes, when the calorific value is very low, the central gas gun or a continuous pilot is kept operational.
If there is the presence of two syngas streams which have very different characteristics in terms of volume and operating conditions, we could provide burners with double external gas scroll.
