Micrometric spherical particles of iron in two narrow size ranges (38–45) µm and (45–53) were injected a bench scale, transparent drop-tube furnace (DTF), electrically heated to 1400 K. Upon experiencing high heating rates (104–105 K/s) the ignited burned. Their combustion behavior was monitored pyrometrically cinematographically at three different oxygen mole fractions (21%, 50% 100%) nitrogen. The results revealed that readily exhibited bright stage followed by dimmer stage. There evidence...
Following the ignition and solid-to-liquid phase transition of a fine (on order 10–100 µm in diameter) iron particle, self-sustained combustion liquid-phase droplet its oxides takes place. The objective current work is to develop an interpretive explanatory model for single particle. A zero-dimensional physicochemical developed assuming fast internal processes, such that rate limited by external oxygen (O2) transport. considers particle covered shell FeO enclosing core Fe. Stefan flow...
This research measured the emissivity, temperature and soot loading of pulverized bituminous coal three types renewable biomass. Combustion occurred in a laboratory-scale drop tube furnace (DTF), where fuels experienced high heating rates ignited burned two distinct phases: devolatilization accompanied by volatile matter combustion envelope flames, sequential char residues. Multi-wavelength spectrometry was used to concurrently determine emissivity burning particles at discrete points their...
A three-color ratio pyrometer has been developed to obtain surface temperatures and high-temperature combustion rates of burning carbonaceous particles. The features performance this instrument are contrasted those a two-color pyrometer, constructed earlier for similar studies. employs visible (0.65 μm) two near-infrared (0.80 0.975 wavelengths. uses single optical fiber capture radiation emitted from particle in laminar flow furnace. Monitoring the events takes place coaxially with flow,...
Oxy-coal combustion is a viable technology, for new and existing coal-fired power plants, as it facilitates carbon capture and, thereby, can mitigate climate change. Pulverized coals of various ranks, biomass, their blends were burned to assess the evolution effluent gases, such NOx, SO2, CO, under variety background gas compositions. The fuels in an electrically heated laboratory drop-tube furnace O2/N2 O2/CO2 environments with oxygen mole fractions 20%, 40%, 60%, 80%, 100%, at temperature...
This work addresses the synthesis of carbon nanomaterials (CNMs) by up-cycling common solid wastes. These feedstocks could supersede use costly and often toxic or highly flammable chemicals, such as hydrocarbon gases, monoxide, hydrogen, which are commonly used in current nanomanufacturing processes for CNMs. Agricultural sugar cane bagasse corn residues, scrap tire chips, postconsumer polyethylene (PE) terephthalate (PET) bottle shreddings were either thermally treated sole pyrolysis...
