Metal fuels, as recyclable carriers of clean energy, are promising alternatives to fossil fuels in a future low-carbon economy. Fossil convenient and widely-available source stored solar energy that have enabled our modern society; however, fossil-fuel production cannot perpetually keep up with increasing demand, while carbon dioxide emissions from combustion cause climate change. Low-carbon carriers, high density, needed replace the multiple indispensable roles including for electrical...
Ignition of iron particles in an oxidizing environment marks the onset a self-sustained combustion. The objective current study is to quantitatively examine ignition characteristics fine governed by kinetics solid-phase oxidation. oxidation rates are inversely proportional thickness oxide layer and calibrated using experimentally measured growth iron-oxide layers over time. Steady-state unsteady analysis have been performed probe dependence critical gas temperature required trigger thermal...
The high temperature ignition of C1−C4 primary alcohols, methanol, ethanol, n-propanol, and n-butanol, is studied behind reflected shock waves. experiments are carried out at pressures 2, 10, 12 atm with argon/oxygen ratios 15, 20 under lean, ϕ = 0.5, stoichiometric, 1, rich, conditions between 1070 1760 K. It observed that the delay time data for n-butanol collapse constant equivalence ratio, pressure, dilution. times methanol comparable other alcohols but show a slightly lower activation...
This paper discusses a set of constraints for the selection metal fuel candidates, along with green recycling techniques.
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...
This paper critically reviews the theoretical and experimental literature regarding fundamental aspects of flames in nonvolatile solid fuel suspensions. Unlike volatile fuels that form continuous premixed gaseous flame sheets, fronts suspensions are driven by heterogeneous reactions localized on surface, or near individual particles. Practically all peculiarities can be linked to this "flame-inside-the-flame" combustion front structure. These enable particles self-heat transition from...
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...
The axial distribution of large biomass particles in bubbling fluidized beds comprised sand and is investigated this study. global local pressure drop profiles are analyzed mixtures at superficial gas velocities ranging from 0.2 to 1 m/s. In addition, the radioactive particle tracking technique used track trajectory a tracer mimicking behavior systems consisting 2, 8, 16% mass ratio. effects velocity mixture composition on mixing/segregation bed components explored by analyzing circulatory...
Stabilized aluminum flames are studied in the products of methane combustion. A premixed methane–air Bunsen flame is seeded with increasing concentrations micron-size powder, and scanning emission spectroscopy used to determine temperature via both continuous monoxide spectra. The burning velocity measured condensed collected analyzed for unburned metallic content. It was observed that, below a critical concentration about , demonstrates incomplete oxidation close flame. Below concentration,...
