NOx Emissions from Bubbling Fluidized Bed Combustion of Lignite Coal

Popis výsledku v původním jazyce

In this paper are discussed experimental results of NOx emission measurement from combustion of two kinds of coals in a bubbling fluidized bed combustor. Tested fuels were Czech brown coal (CBC) and German young brown coal (GYC). Both fuels have different nitrogen content. Experiments were performed in the pilot scale experimental BFB unit with power output at 300 kW. In the work was studied influence of several parameters on NOx formation. These parameters were effect of nitrogen content in the fuel, effect of oxygen concentration in the bed, effect of bed temperature, effect of air staging and effect of fluidization velocity. Significantly different behaviour of the fuels was found. Although GYC has lower nitrogen content, it is more reactive and produces higher NOx emissions. The biggest dependence of NOx production for CBC was found for the effects of air staging and fluidization velocity. With increasing fluidization velocity and lowering the amount of secondary air increase the N
