Coal drying in Europe Part 1 | World Coal

This involves the simultaneous milling and drying of raw coal immediately before combustion in a beatertype mill, aerated by the hot flue gas drawn off at 900 1000°C from the upper levels of the furnace chamber. Such predrying requires a boiler substantially larger to cope with the large quantity of evaporated water.

Oxyfuel combustion for CO2 capture in power plants

Introduction. Oxyfuel combustion is one of the leading technologies considered for capturing CO 2 from power plants with CCS. This involves the process of burning the fuel with nearly pure oxygen instead of air. In order to control the flame temperature, some part of the flue gas are recycled back into the furnace/boiler.
