Apr 11, 2019 The gross calorific value GCV of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to predict GCV using either moisture content andor ash yield or using entire proximate and ultimate coal analysis data.
same moisture content but an ash content of 6 may be difficult to burn as it has an effective moisture of 55,26 . The first fuel has a moisture to combustible ratio of 1.181 and the second a ratio of 1.291 i.e. almost 10 more moisture per unit mass of combustible material whilst fuel moisture has only gone up by 2.26 points.

Correlation analysis was carried out to analyze the individual effect of moisture, volatile matter, ash and fixed carbon on the gross calorific value GCV. It is observed that moisture , ash have adverse impact and reduce the gross calorific value whereas volatile matter ,fixed carbon have
Oct 07, 2019 Along with moisture and ash contents, the percentage of volatile matter in a coal sample is needed to calculate the fixed-carbon content of a coal. Many electric utilities prefer coals within a narrow range of volatile matter 25 to 35 percent for optimal flame stability in the boiler Thomas, 1992.
Aug 04, 2016 The effects of moisture in coal on the power block boiler-turbine-generator unit are decreased in boiler efficiency Figure 7, decreased overall unit efficiency increase in heat rate Figure 8 and decrease in unit load.. The boiler efficiency decreases due to increase in moisture and the unit heat rate increases. This results in increased cost of generation.
