This chapter describes the process of power generations technologies using brown coal. A number of advanced technologies have been or are being developed to improve thermal efficiency, to reduce NOx, SOx and CO2 emissions and to reduce the cost of electricity. These include the circulating fluidized bed combustion (CFBC), pressurized fluidized bed combustion (PFBC), integrated gasification combined cycle (IGCC), and integrated gasification fuel cell (IGFC) technologies. There are specific issues to consider in the utilization of high-moisture low-rank coals for power generation and, in particular, the need to incorporate a coal drying process. Other properties of low-rank coals such as coal reactivity, alkalinity of the ash and the difficulty of handling raw coal also impact the design of the system components. The chapter describes the analyses of various advanced power generation technologies using brown coal. The efficiencies determined here are based on the first law of thermodynamics. This is essentially an accounting of energies entering and exiting the system. Efficiencies are evaluated as ratios of energy quantities and are often used to assess the performance of a system and to compare various systems.
