The achievement of a steady rate of slag tapping in entrained-flow gasifiers relies on their continuous, smooth operation. In turn, this requires the viscosity of coal ash slags to be within 5–25 P...

High-iron coal is widely distributed throughout China and could be used as the feedstock for slagging gasifiers. To enable cleaner, efficient, large-scale use of high-iron coal by the slagging gasifier, a solid understanding of coal ash fusion behavi

The viscosity of slags containing crystallized solids is always of great interest for materials scientists working in high-temperature slag processing, as it strongly affects slag flow behavior. Different slag characteristics, such as liquid phase co

The presence and composition of ash in solid waste streams produced by the thermochemical processes can affect the further disposal or use of the waste. This study characterised the chemical species, mineralogy and trace element mobilisation in labor

Alkali species in coal play an important role in mineral matter reactions during gasification. Brown coal ashes can be high in sodium (up to 20 wt%), which interacts with other minerals to significantly affect the formation of slag (liquid phase). At

The crystallisation in coal ash slags plays a critical role in coal combustion and gasification. The stable operation of a boiler or entrained-flow gasifier is vitally dependent on the easy, continuous removal of combustion by-products in the form of

To achieve a stable slag-tapping process in entrained-flow coal gasifiers, the acceptable viscosity of coal ash slag is within 5–25 Pa·s in the temperature range 1200–1500 °C and the tapping temperature should be above the temperature of critic

Utilisation of brown coal in slagging gasification technologies requires a detailed assessment of coal ash chemistry in terms of potential slagging behaviour. We investigated the phase compositions of four categories of brown coal ashes and synthetic

Iron-based oxides are considered as potential oxygen carriers in coal chemical looping combustion. However, their redox or oxidation behaviour can be affected by coal mineral matters. The interactions between oxygen carriers and coal ashes depend str
