Understanding the ignition behaviour of coal is of utmost importance for the design of boilers and control of the combustion process. In recent years there has been an increasing utilisation of coal blends for combustion, ...

A laboratory-scale technique has been developed for assessing changes in the combustion reactivity of coal blends with blend composition. The test consists of the incomplete combustion of a batch of coal particles in a ...

Blending coals as fuel for pulverised-fuel-fired power stations provides a way of minimising costs and increasing fuel flexibility. The use of blends can, however, introduce operating difficulties, such as poor ignition, ...

The interaction effects between sugarcane bagasse and a Brazilian coal during co-firing were investigated by means of thermal decomposition behavior, comparison between theoretical and experimental results, activation ...

Although coal blends are increasingly utilized at power plants, ash slagging propensity is a non-additive property of the pure coals and hence difficult to predict. Coal ash tendency to slag is related to its bulk chemistry ...

The aim of this study is to predict efficiency deviations in the combustion of coal blends in power plants. Combustion of blends, as compared to its single coals, shows that for some blends the behavior is non-additive in ...

A multiple reaction model (MRM) was used to characterize the kinetics of pyrolysis of single coals and binary blends; the MRM represents the kinetics through a continuous distribution of the activation energies of the ...

Coal blends are increasingly utilised at power plants with significant savings and without breaking environment regulations. However, evidence of interaction among the coals requires the study of some parameters that affect ...
