Emissions of SO2, NO and N2O in a circulating fluidized bed combustor during co-firing coal and biomass

Release characteristic of different classes of sodium during combustion of Zhun-Dong coal investigated by laser-induced breakdown spectroscopy

“…Because of the abundant reserves, coal is still the main energy source for power generation in China [1] despite the numerous associated pollutants, e.g., sulfur dioxide (SO 2 ), nitrogen oxides (NO x ), and particulate matter (PM) [2][3][4]. Besides the combustible organic component, coal also contains several kinds of mineral matter including sodium (Na) compounds.…”

Emission of NOx and N2O from co-combustion of coal and biomasses in CFB combustor

“…Teixeira and Lora (2004) studied the NO x emission from bagasse boilers in Brazil. Xie et al (2007) presented their study resulted of the emissions of SO 2 , NO and N 2 O in a bench scale CFBC. Armesto et al (2003) studied the coal characteristics on the N 2 O formation in a FBC.…”

Effects of operational parameters on emission performance and combustion efficiency in small-scale CFBCs

“…Increasing excess air results in lower levels of NO x formation which is generated due to combustion efficiency decrease caused by lower bed temperature. NO x emissions can be effectively reduced in oxygen-rich atmosphere as the results of the study of Xie et al (2007) suggests. Earlier studies carried out by Bhatt (2007) suggests that minimizing excess air to their thread bare levels led to unusually high levels of NO x , as the NO x in flue gas is increased by 35% for a decrease of excess air from 20 to 10% for coal (Bhatt, 2007).…”
