Journal ArticleDOI
Thermogravimetric assessment of combustion characteristics of blends of a coal with different biomass chars
TL;DR: In this article, the results of non-isothermal combustion studies in general depict that blends containing less than 50% biomass char are better performing as compared those with higher biomass char content.
Journal ArticleDOI
Air- and oxygen-blown characterization of coal and biomass by thermogravimetric analysis
TL;DR: In this paper, the results of air-blown combustion and oxy-combustion kinetic characterization were compared with two different isoconversional methods (Flynn-Wall-Ozawa and Kissinger-Akahira-Sunose) of different kinds of coal (from Italy, South Africa and Hungary) and biomass (pine and eucalyptus chips) by thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) together with assessment of different characteristic combustion parameters.
Journal ArticleDOI
Pyrolysis and Combustion Behavior of Coal Gangue in O2/CO2 and O2/N2 Mixtures Using Thermogravimetric Analysis and a Drop Tube Furnace
TL;DR: In this article, pyrolysis and combustion characteristics of a low-rank coal gangue have been investigated under oxy-fuel (O2/CO2) and air (N2/O2) conditions using a drop tube furnace and thermogravimetric analysis.
Journal ArticleDOI
A comparative study on co-combustion performance of municipal solid waste and Indonesian coal with high ash Indian coal: A thermogravimetric analysis
TL;DR: In this article, an attempt has been made to compare the co-combustion characteristics of hydrothermally treated MSW and Indonesian coal with high ash Indian coal, so as to replace the coal with MSW.
Journal ArticleDOI
Thermochemical and combustion behaviors of coals of different ranks and their blends for pulverized-coal combustion
TL;DR: In this article, a laboratory-scale slit burner was used to study the combustion characteristics of a practical flame with a high heating rate and jet velocity, and the results of thermogravimetric and differential thermal analyses (TGA and DTA) showed that low-rank coals influenced the ignition temperatures of blends whereas high-rank coal influenced their burnout temperatures.

Journal ArticleDOI
A char morphology system with applications to coal combustion
TL;DR: In this article, a char morphology system based on the physical and optical characteristics known to influence the burning of pulverized coal is outlined, and the proportions of different pyrolysis char types produced by any coal are shown to depend on coal rank, petrographic composition, maceral fusibility, and possibly ash content and composition.
Journal ArticleDOI
Reactivity assessment of coals via a weighted mean activation energy
TL;DR: In this article, a method was developed for describing the reactivity or combustibility of solid fuels, such as lignite, bituminous coals and petroleum coke, in terms of a weighted mean apparent activation energy, derived from simultaneous TG DTG readings on a 20 mg sample heated at a constant rate in a flowing air atmosphere.
Journal ArticleDOI
Techniques to determine ignition, flame stability and burnout of blended coals in p.f. power station boilers
TL;DR: In this article, the performance of coal and anthracite blends was evaluated in laboratory, pilot, and full-scale facilities, and the results showed that blending a high-volatile coal with a low-varying coal can improve the ignition, flame stability and burnout of the blends.
Journal ArticleDOI
Thermogravimetric analysis of the co-combustion of coal and sewage sludge ☆
TL;DR: In this paper, the Arrhenius kinetic parameters were calculated from the experimental results, considering the process as a series of consecutive first order reactions for coal-sludge blends.

Combustion studies by thermogravimetric analysis: 1. Coal oxidation
TL;DR: In this article, the non-isothermal oxidation of coal chars was investigated by conventional thermogravimetric analysis (tga) over the temperature range 450-650 °C.
