Abstract

Research on coal and products from coal, including products of combustion, is becoming more concerned with environmental applications and with coal products from liquefaction, pyrolysis, and combustion. PROXIMATE AND ULTIMATE ANALYSISRapid Methods. Samples (A2) described quick laboratory methods for determinations such as ash, moisture, sulfur, and sodium and also discussed the use of statistics. Rexin (A2) reported on methods for rapid and reliable approximation ofASTTM procedures for use in coal quality control in mining; determinations discussed included microwave air-drying, ash, sodium, and calorific values.

Spectroscopic and Thermal Degradation Study of Cow-Dung during Combustion and Pyrolysis

“…In the present study, the gases evolved during pyrolysis and combustion of cow-dung are investigated using TG-FTIR-MS. This is a powerful method for the characterization of the gaseous products, analysis of the decomposition kinetics, investigation of the combustion conditions and the parameters during the combustion of a variety of fuels [21]. Helium is used as the carrier gas during pyrolysis and the weight loss with temperature is recorded automatically.…”

Characterisation of coal slurries for introduction into ICP OES for multi-element determinations

“…[1][2][3][4] Accurate information on the quantity and quality of coal is required by policy makers in order to make informed decisions regarding foreign policy objectives, technology transfer policies, environmental and health assessments, byproduct use and disposal of coal wastes. [5][6][7] Coal is a complex material with more than 20 variables that must be determined for complete characterisation. Real time information on coal quality leads to better and efficient management of coal stock piles and improved plant performance.…”
