An entrained flow reactor has been used to characterize the slagging behaviour of twelve
coals/blends, under different experimental conditions. Besides measuring the weight of the …

A CFD model that simulates particle impaction and sticking has been developed for
predicting the ash deposition characteristics for the co-combustion of South African Coal …

During the combustion of coal and biomass blends, ash particles are deposited on the
furnace wall, or on the heat transfer surfaces, and gradually they become sintered and …

The slagging behaviour of 12 different coals/blends was analysed in an entrained flow
reactor and compared with predictions using a wide range of empirical indices. Large …

This paper presents the results of a comprehensive program of experiments in which fly ash
particles were impacted under controlled conditions against a flat steel surface. The overall …

Coal–biomass mixtures have been prepared and combusted on the Imperial College
entrained flow reactor (EFR). Five different biomasses were mixed with two bituminous coals …

The introduction of low-NOx burners to UK coal-fired power stations has changed the nature
of ash deposition within the boilers. Lower peak flame temperatures and the delayed mixing …

A major UK collaborative research programme to address all aspects of slagging in
bituminous coal-fired boilers has recently been completed. The 3 1/2-year programme …

In this thesis, a model that couples a reduced alkali kinetic mechanism for alkali sulphate
formation during biomass combustion with an ash deposition model using computational …

This study investigated the rebound behavior of SiO2 particles normally impacting a planar
surface under different temperature conditions. The system has been characterized for an …
