Therefore John Joyce's research into low NO x burners revolved primarily around surface combustion techniques. Another issue was the effect combustion temperatures have on the formation of NO x . John Joyce's task became even more challenging when he decided not to direct his development towards radiant type surface combustion tiles.
The main drawback of lean-burning is that a complex catalytic converter system is required to reduce NOx emissions. Lean-burn engines do not work well with modern 3-way catalytic converter—which require a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions—so most modern engines tend to cruise and ...
The amount of NOx produced depends on the combustion temperature. [2] When the combustion takes place at a lower temperature the NOx emissions are reduced. [2] Gas turbines with DLE technology were developed to achieve lower emissions without using water or steam to reduce combustion temperature (Wet Low Emission (WLE) technology).
Another method of fuel staged combustion is fuel biasing. In fuel biasing, combustion is staged by diverting fuel from the upper-level burners to the lower ones or from the center to the side burners. The aim is to create a fuel-rich lower or central zone and a fuel-lean upper or side zone in order to achieve complete burnout.
FBC smoke tube boiler. Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

Bowin low NO x technology is a hybrid of staged-premixed-radiant combustion technology with major surface combustion preceded by minor radiant combustion. In the Bowin burner, air and fuel gas are premixed at a ratio greater than or equal to the stoichiometric combustion requirement. [ 39 ]
Preassembled process unit for air pollution control, i.e., a thermal oxidizer, being installed at a work site. Schematic of a basic thermal oxidizer A thermal oxidizer (also known as thermal oxidiser , or thermal incinerator ) is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high ...
