High soot yield in pyrosim
Webfeaturing high thermal efficiency and almost 100% carbon capture, attracts significant attention but operates at even higher pressures (e.g., 10 0–30 0 bar). The increased pressures in combustion lead to one major concern: high soot yield. The high soot yield under elevated pressures was observed and investigated in many lam- WebWornat et al. 26 also observed for a similar coal that about 20 wt % of the coal was converted to soot at high temperatures and long residence times. The maximum soot yield obtained during...
