Effect of Fe on NO release during char combustion in air and O

Ying GU, Xiaowei LIU, Bo ZHAO, Minghou XU

Frontiers in Energy 2012, Volume 6, Issue 2, Pages 200-206 doi: 10.1007/s11708-012-0181-2

Abstract: The chemistry of char was probed by studying nitrogen release under the reactions with air and oxy-fuelThe results show that the particle size of char generated at 1073 K in CO is larger than that in N .However, at 1573 K, it is smaller in CO atmosphere due to particle breaking by gasification of char

Effects of pyrolyzed semi-char blend ratio on coal combustion and pollution emission in a 0.35 MW pulverized

Yonghong YAN, Liutao SUN, Zhengkang PENG, Hongliang QI, Li LIU, Rui SUN

Frontiers in Energy 2021, Volume 15, Issue 1, Pages 78-90 doi: 10.1007/s11708-020-0678-z

Abstract: ratio on combustion and pollution emission characteristics for co-combustion of Shenmu pyrolyzed semi-charThe NO concentration was 425 mg/m at 6% O and char burnout was 76.23% for the 45% blend ratio.that the change of standoff distance and NO emission were not obvious when the blend ratio of semi-charThe goal of this study is to achieve blending combustion with a large proportion of semi-char withoutSo, an SC blend ratio of no more than 45% can be suitable for the burning of semi-char.

Keywords： pulverized-coal combustion pyrolyzed semi-char ignition characteristics pollution emission char burnout

Effect of temperature on Lu’an bituminous char structure evolution in pyrolysis and combustion

Yandi ZHANG, Yinhe LIU, Xiaoli DUAN, Yao ZHOU, Xiaoqian LIU, Shijin XU

Frontiers in Energy 2021, Volume 15, Issue 1, Pages 14-25 doi: 10.1007/s11708-020-0805-x

Abstract: particles, coal structure evolution will be affected by the ash behavior, which will further affect the charLu’an bituminous char and ash samples were prepared at the N and air atmospheres respectively acrossA scanning electron microscope (SEM) was used to observe the morphology of char and ash.SEM results indicated that the number density and physical dimension of ash spheres exuded from the charFurthermore, the constantly increasing pyrolysis temperature also caused the reactivity of char decrease

Higher heating value prediction of torrefaction char produced from non-woody biomass

Nitipong SOPONPONGPIPAT,Dussadeeporn SITTIKUL,Unchana SAE-UENG

Frontiers in Energy 2015, Volume 9, Issue 4, Pages 461-471 doi: 10.1007/s11708-015-0377-3

Abstract: The higher heating value of five types of non-woody biomass and their torrefaction char was predictedcarbon and volatile matter had a strong effect on the higher heating value prediction of torrefaction charThe high ash fraction found in torrefied char resulted in a decrease in prediction accuracy.

Keywords： higher heating value correlation biomass proximate analysis ultimate analysis
