This zone had shifted from the region between primary and secondary air in LNASB to a region between inner and outer secondary air.
All are lost in the firing – the disaster probably due to Michael's imperfect construction of an inlet for secondary air".
The influences of secondary air to primary air ratio and spraying water flow rate were studied.
The injection of secondary air with high velocity in the freeboard effectively reduces PAH emissions.
The controlled system was the secondary air flow system in a fluidized-bed combustion power plant.
We examine the influences of various parameters such as the relative position of the over-fire air (OFA) nozzle, over-fire air ratio (19.1%), primary air ratio, inner secondary air ratio, outer secondary air ratio, inner secondary air swirling intensity, and outer secondary air swirling intensity on NOx formation and unburned carbon in fly ash.
The introduction of secondary air (SA) in fluidized bed boilers is of important engineering significance.
The secondary air temperature is always the same as the inlet temperature.
A slight decrease in the NOx concentration was observed upon injection of secondary air.
In order to reduce the CO emissions, we modified the configuration of the secondary air nozzles of the incinerator plant, based on the jet penetration factor and momentum flux ratio of secondary air to primary air.
Finally, the optimal operation of secondary air and separated overfire air were achieved by using optimization model, which could provide references for the adjustment of secondary air and separated overfire air.
