In Korea, oil-palm empty fruit bunches (EFBs), which are byproducts of the crude palm-oil milling process, among most promising potential energy sources for power plants. However, slagging and fouling characteristics EFBs during combustion have not yet been fully studied. Accordingly, in this study, we investigated fundamental ash behavior comparison to that wood pellets (WPs) using a thermomechanical analyzer (TMA) drop-tube furnace (DTF). Ash melting deposition particles were with...
Pre-treatment of biomass has garnered significant research attention to facilitate utilization. This study examines the effect torrefaction on pyrolysis characteristics kenaf (Hibiscus cannabinus L.), which grows in South Korea and a relatively short life cycle as well low production cost among herbaceous biomass. In this study, raw (RK) torrefied (TK) were prepared an inert atmosphere. Torrefaction was carried out bed reactor for 30 min at 503, 523 553 K, performed six heating rates...
Biomass can be upgraded via torrefaction, and torrefied kenaf (TK) is a fuel that allows blending with coal at high ratios. In the present study, raw (Hibiscus cannabinus L.) (RK) was 523 K for 30 min then mixed Vietnamese anthracite (NinhBinh, NB) before co-pyrolysis. Thermogravimetric (TG) analysis used to evaluate behavior of RK, TK, blended RK/TK during co-pyrolysis biomass ratios (BBRs) 0, 25, 50, 75, 100 wt %. The TG derivative thermogravimetry curves mixture NB RK (NBRK) were similar...
Petrographic analysis can provide valuable information about pulverized coal used in coal-fired power plants. In this study, petrographic was to determine the effect of blending on combustion low-rank from Mongolia and two bituminous coals Russia. After these based their calorific values combusting them a drop tube furnace, unburned combustibles char were analyzed. The rank, determined mean random vitrinite reflectance, closely correlated with proportion each single blend. Char component...
