Hot gas is mostly generated by the combustion and has large thermal energy but usually contains particulate matter at a high concentration. Hence it has to be removed before introducing it to a gas turbine at high temperatures to utilize its thermal energy.Cleaning technology at high temperature has been studied closely in relation to the development of combined power generation technology such as Integrated Gasification Combined Cycle and Pressurized Fluidized Bed Combustion Combined Cycle power generation. Different from the ordinary conventional dust collection technology, not only the particle collection but also the interaction between gas and filter surface have to be considered in its development since physical and chemical properties of dust change at elevated temperature and pressure. In other words, basic understanding of these properties of dust and filter materials and their interaction are essential for the development of hot gas cleaning technology.In this paper, recent developments in the field of hot gas cleaning has been reviewed.
