Electrical capacitance tomography (ECT) is a non-intrusive and non-invasive internal visualization tool that facilitates improved quantification by producing cross-sectional distribution information for any kind of multiphase flow. In a coal-fired power station, there are some concerning issues such as the sedimentation of pulverized coal in the piping system before it reaches the boiler system and the non-uniformity of its velocity, which contributes to a reduction in electricity generation and higher carbon dioxide emissions. The aim of this paper is to provide a review based on various research works on pulverized coal that utilized ECT system. This paper also consists of principle of ECT, image reconstruction, and velocity measurement. Further research and works will be executed based on the preliminary data gained to improve the existing works.
