Slag Flow an overview ScienceDirect Topics

The slag behavior of coal ash as a function of temperature was classified into Type I and Type II. In Type I, cooling leads to Newtonian flow and increases the viscosity of slag, whereas in Type II cooling leads to non-Newtonian flow and a sharp increase in the viscosity of the slag to a critical value, where the corresponding temperature is denoted as the temperature of critical viscosity (T

Slag Behavior in Gasifiers. Part I: Influence of Coal

In the entrained-flow gasifiers used in integrated gasification combined cycle (IGCC) plants, the majority of mineral matter transforms to liquid slag on the wall of the gasifier and flows out the bottom. However, a small fraction of the mineral matter is entrained (as fly ash) with the raw syngas out of the gasifier to downstream processing.

Additionally, Microbeam also provides Plant Performance Index (PPI) calculations, based on plant operational parameters input and fuel quality. Plant personnel can use this data to optimize boiler operations in order to maintain slag flow, minimize NOx formation, and minimize ash deposition. Here’s how CQI & PPI, aka the “Tools,” work . . .

Simulation of Ash Deposition Behavior in an Entrained

2015-4-16  Most entrained-flow coal gasifiers are designed to operate at tempera-tures above the ash fusion temperature, in which the ash melts and deposits along the wall, forming a slag layer. Up to 90% of the ash can be discharged as molten slag from the bottom of the furnace or gasifier to a water- quenched slag hopper, where it forms crystal pellets [2].
