Study of coal ash deposition in an entrained flow reactor: Assessment of traditional and alternative slagging indices

摘要: The slagging behaviour of 12 different coals/blends was analysed in an entrained flow reactor and compared with predictions using a wide range empirical indices. Large discrepancies were obtained most cases, both respect to experimental results (in terms capture efficiency energy-based growth rate) among the A new approach is proposed, which traditional expressions are modified account for other parameters influence on deposition phenomena: aerodynamic diameter total mass mineral matter injected coal. Each these factors resulted improved correlations between observations all indices analysed, together good agreements achieved several thought confirm validity proposed.
