Char deposition on the heat exchanger tube of a coal gasifier inhibits heat transfer to steam line system, resulting in plant thermal efficiency decreasing. In order to commercialize IGCC power plant, effects of coal type or operational condition on char deposition behavior to the heat exchanger tube should be predicted. At 200T/d pilot plant, three kinds of coal have been tested, there was a great difference in heat transfer characteristics of heat exchanger among coal types. In this study, char re-entrainment tests and deposition tests focusing on char size distribution were conducted using three kinds of char that have same size distribution as those of 200 T/d char. Furthermore, reasons of differences in char deposition characteristics among three coal types were discussed.
