  Combustion behaviors, PM formation, and ash deposi

  This figure illustrates our fundimental researches on coal combustion, as a function of coal particle residence time in high-temperature ambiences. Combined with advanced in-situ diagnostics as well as standard off-line measurements, aspects like particle ignition, surface temperature, fragmentation properties, minerals relea...

  Particulate Formation and Ash Deposition of Oxy-Co

  The characteristics of both particulate formation and ash deposition play an important role in retrofitting the conventional air-fired coal power plant into the recycled oxy-fuel plant. An intensively comparative study was performed with a 25 kW quasi one-dimensional down-fired pulverized coal combustor for clarifying the dif...

  Dynamic behavior of Na in combustion

  We examine the dynamic behavior of sodium (Na) release during the pulverized coal combustion of Zhundong lignite using a laminar, Hencken flat-flame burner technique. By subtly utilizing the gap between the excitation energies of the gas and particle phases, a new low-intensity laser-induced breakdown spectroscopy (LIBS) is d...

  Dynamic Behavior of Biomass Ash Deposition

  The severe fouling and slagging problem due to high alkali and alkaline earth metal content still limits the applications of self-sustained biomass power plants. It is essential to study dynamic behavior of ash deposition in pure biomass combustion. Three kinds of biomass, saw dust, wheat straw and corn stover, were burned in...
