Experimental and kinetic studies on NO emission during pulverized coal preheating-combustion process with high preheating temperature
Wang, Shuai; Zhu, Guangqing; Niu, Yanqing; Ding, Yiyu; Hui, Shi'en (Peer reviewed; Journal article, 2021)In this study, two connected drop tube furnaces (DTFs) were used to clarify the NO emission characteristics during the high-temperature preheating-combustion process. The most important factors, including preheating ... -
Gasification of High Heating-rate Biomass-derived Chars at Elevated Temperatures
Li, Tian; Niu, Yanqing; Wang, Liang; Løvås, Terese (Journal article; Peer reviewed, 2017)In this study, gasification behavior of high heating-rate chars were investigated using an entrained flow reactor with an optical particle-sizing pyrometer. Two biomass chars produced from forest residue and torrefied ... -
High temperature gasification of high heating-rate chars using a flat-flame reactor
Li, Tian; Niu, Yanqing; Wang, Liang; Shaddix, Christopher; Løvås, Terese (Journal article; Peer reviewed, 2018)The increasing interest in gasification and oxy-fuel combustion of biomass has heightened the need for a detailed understanding of char gasification in industrially relevant environments (i.e., high temperature and ...
