Ash Deposition Behavior during Char−Slag Transition under

Ash deposition experiments at various conversions of a bituminous coal were performed under gasification conditions using a laminar entrained-flow reactor and a deposition probe. Results showed that the particle capture efficiency (a measure of ash deposition propensity) was a function of coal conversion. In particular, the capture efficiency increased dramatically at a critical conversion

The Surface Characteristics and Reactivity of Residual Carbon

In a slagging entrained-flow coal gasifier, a large portion of the inorganic matter will form liquid slag that may have strong physical and chemical interactions with char. Understanding the char−slag interaction is important for improving the modeling and design of gasifiers. This paper reports the characteristics of residual carbon in both coarse and fine slag from a typical entrained-flow
