This critical ash depends upon the pricing structure of the coal. For example, the pricing mechanism for non-coking coal in India is grade-based as shown in Table 1.The Useful Heat Value (UHV) is calculated on the basis of an empirical relationship given by (1) UHV = 89 00 − 138 A + M where A and M are ash and moisture contents, respectively. …
Ultrasonic-assisted coal-water slurry preparation. The utilization of coal-water slurry (CWS) as a liquid fuel has been a priority in many countries [115]. However, several technological difficulties related to CWS technology such as lower stability and poor rheological behaviour of CWS limits its use in large-scale applications.
