And reactidon rates of coal burnout and nitrogen and sulfur pollutant formation. ( local samples of combustion products have been extracted from the pulverized coal 'i combustor using water-quenched sample probes.. The combustion rates of coal chars: a review i. w. smith csiro division of fossil fuels p.o. box 136 north ryde, nsw 2113, australia a brief description is given of devolatilization of raw coal and combustion of the residual char. major achievements in the study of devolatilization and important areas for further. Burnout component-jc-char is the char burnout of the component jc coal in the blended coals, and burnout pure-jc-char is the char burnout of the pure jc coal. the competition between the promotive and inhibitive effects influences the combustion characteristics and the additive/non-additive behavior of blended coals..
The char burnout and the release rates of c and h were largest along the burner center; as the radius increased, they decreased with the increase of coal-feed rates. at the center of the burner ( r 2 = 0), char burnout and release rates of c and h decreased from 83%, 81%, 95% to 75%, 72%, 87% as coal-feed rates increased from 2 to 5 tonnes/h.. The influence of chlorine additives on pulverized coal combustion rate was analyzed and the micrograph of unburned pulverized coal (upc) was observed by sem in order to analyze the influence mechanism of chlorine additives.. The 149 engine for mine-haul trucks has a rated speed of 1900 rpm; (2) reasonable fuel economy and coal burnout rate; (3) reasonable cost of the engine design concept and cws fuel compared to future oil prices..
