Particulate Matters Emitted from Maize Straw Burning for Winter Heating in Rural Areas in Guanzhong Plain,China:Current Emission and Future Reduction

Zhenxing Shen  Jian Sun  
【摘要】:Maize straw smoldering in "Heated Kang" is the traditional way for heating in winter in rural areas of Guanzhong Plain.This smolder procedure produced large quantities of pollutants and became a big problem in rural and urban areas.The EFs of trace gases(NOx,CO,CO2) and particles(PM_(2.5),OC and EC) and the particle-size distributions from maize straw burning in a traditional ‘Heated Kang'(Scenario 1) and maize straw(Scenario 2) and its briquettes(Scenario 3) burning in an advanced stove were determined in this study.EFs of pollutants from an advanced stove fired with maize straw and maize-straw briquette being conducted in a laboratory was to find the new measure to reduce the pollution emissions.Modified combustion efficiency(MCE) was also measured and calculated in this study.And the results showed that MCE had a strong positive correlation with NO,NO_2 and CO_2 emissions;in contrast,CO concentrations had an obvious negative correlation with MCE.And the lowest EFCO was observed in Scenario 3 in which the MCE was the highest,indicating that the advanced stove with briquetting technology could effectively reduce the CO emission.The results showed that the EFs of PM_(2.5) for 3 scenarios were 38.26 ± 13.94 g·kg~(-1),17.50 ± 8.29 g·kg~(-1) and 2.95 ± 0.71 g·kg~(-1),respectively.The EFPM from straw burning in the ‘Heated Kang' was ten-times higher than straw briquette burning.The differences in EFs were most likely caused by combustion related parameters,that is,air supply,burning rate,MCE,etc.Comparing EFs of pollutants from 3 scenarios indicates that both briquetting of straw and advanced stove with air distribution system could efficiently reduce pollutants emission especially for Scenario 3.EFs of PM_(2.5),OC and EC and water soluble ions all have over 90% reduction between Scenario 1 and 3.Moreover,The OC/EC ratios from residue burning(35.1 and 10.8) were much higher than those from straw briquette burning(range:1.0 to 8.3),and the ratios were strongly affected by air supply.Low temperature OC(OC1 and OC2) dominated the maize-straw burning particles whilehigh temperature OC(OC3 and OC4) were dominant in briquette-burning particles.Low temperature(EC1) was the main EC component in all samples.The EFs of K+ and Cl-had strong correlations with the EFPM in all sizes of particles due to their high abundances in both the maize straw and briquettes while other ions did not show such good correlations,especially in fine particles.Converting to briquettes and advanced stoves for residential heating could reduce PM_(2.5) emission from 48.3 Gg to 3.59 Gg,OC from 19.0 Gg to 0.91 Gg,EC from 1.7 Gg to 0.17 Gg and over 90% reduction on total water soluble ions in the whole region.A box model simulation for the Guanzhong Plain indicated that this conversion would lead to a 7.7% reduction in PM_(2.5)(from 130 to 120μg·m~(-3)) in normal conditions and a 14.2% reduction(from 350 to 300 μg·m-3) in hazy conditions.The results highlighted that the burning straw briquettes burning in advanced stove can effectively reduce pollutants emitted and can improve the energy use efficiency in comparison with maize straw smoldering in "Heated Kang".
