Journal ArticleDOI
The combustion rates of coal chars: A review
TL;DR: In this article, a brief description of coal develatilization and combustion of residual char is given, and a theoretical consideration is given to the changes in the size, density, and pore structure of coal chars as they burn.
Journal ArticleDOI
Determination of the soot absorption function and thermal accommodation coefficient using low-fluence LII in a laminar coflow ethylene diffusion flame
TL;DR: In this article, the effect of the fractal structure of soot aggregates on the rate of heat loss to the surrounding gas was investigated in the presence of relatively low laser fluences under which soot particles are heated to temperatures below 3500 K.
Journal ArticleDOI
The products of the high temperature oxidation of a single char particle in an electrodynamic balance
TL;DR: In this article, the authors measured the CO2/CO ratio formed by the heterogeneous reaction on the char surface for temperatures up to 1670 K and found an exponential decrease with a temperature coefficient of 3100/K.
Journal ArticleDOI
The oxidation of graphite powder in flame reaction zones
TL;DR: In this paper, the rate of burning of small concentrations of fine graphite powder has been measured in a flat, laminar weak methane-air flame at sub-atmospheric pressure.

A new determination of the emissivity of tungsten ribbon
TL;DR: In this paper, a new determination of the spectral emissivity of tungsten has been performed in order to supply more reliable data for the use of the Tungsten striplamp as a standard source of radiation.
Journal ArticleDOI
Measurements of the effect of rank on combustion rates of pulverized coal
TL;DR: In this article, the surface reaction rate of coal chars was measured for a range of eleven coals, high rank and low rank, swelling and nonswelling, using a luminar flow furnace technique described in an earlier paper.
Journal ArticleDOI
Heat Transfer in Chemically Reacting Mixtures. I
TL;DR: In this paper, it was shown that if the reaction rates are fast in either the forward or the reverse direction, the assumption of local chemical equilibrium (which is equivalent to the thermodynamics of irreversible processes) is very good.

Gas Thermal‐Conductivity Studies at High Temperature. Line‐Source Technique and Results in N2, CO2, and N2‐CO2 Mixtures
A. A. Westenberg,N. deHaas +1 more
TL;DR: In this paper, the thermal wake widths downstream of a steady line source of heat in a uniform laminar flow of the test gas are used to predict the thermal conductivity of N2, CO2, and N2 CO2 mixtures up to 2000°K with what is believed to be the most reliability which is presently possible.
