Slag Splashing: simulation and analysis of the slags conditions

Journal of Materials Research and Technology, 2019
The successful application of the repair and prevention of LD converters refractories technique called Slag Splashing requires a close control of the slag physicochemical properties (basicity, viscosity and surface tension), as well as suitable selection of operational parameters and geometric configurations.

Modeling of a coal-fired slagging combustor: Development of a slag submodel

, 2007
In a slagging combustor or furnace, the high combustion temperature makes the molten slag layer cover the wall and capture the particles. If these particles contain combustible matter, they will continue to burn on the running slag.

An improved index to predict the slagging propensity of woody biomass on high-temperature regions in utility boilers [PDF]

, 2023
Ash deposition-related issues adversely affect the thermal transfer and cause corrosion to biomass fired utility boilers. Various models have been proposed to estimate the slagging propensities for firing biomass fuels of different origins.

Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and
