Mitigating the Effects of Flexible Operation on Coal

2011-1-8 · Coal-fired power generating units in the U.S. continue to switch from high-capacity-factor operation to various modes of flexible operation. Cycling and load following are not new.

Exergy Analysis and Efficiency Improvement of a Coal

This research conducts exergy analysis in one unit of a coal-fired power plant in Central Queensland, Australia as a case study. The exergy analysis identifies where and how much exergy is destroyed in the system and its components. Based on the analysis, it assesses and discusses different options to improve the efficiency of the system.

Analysis of Heat Rate Improvement Potential at Coal

2015-5-19 · potential for heat rate improvement at existing coal-fired generating plants. Leidos performed a statistical analysis of the heat rate characteristics ofcoal-fired generating units modeled by EIA in the EMM. Specifically, Leidos developed a predictive model for coal-fired electric generating unit heat rates

Thermodynamic models and energy distribution of singl

2011-3-5 · A coal-fired power unit frequently operates under unsteady conditions; thus, in order to acquire scientific energy analysis of the unit, thermodynamic analysis of a single-phase heated surface in a boiler under such conditions requires investigation. Processes are

Sensitivity Analysis of a 50+ Coal-Fired Power Unit

2015-12-24 · In the case of thermodynamic calculations of cycles of coal-fired power units, the obtained values of the gross and net efficiency of electricity generation depend on assumed values of the input data, i.e. on the boiler power efficiency, the turbine internal efficiency, the condenser pressure, the power unit own-needs index, the pressure

DLUIORZWRFRDOSDUWLFOHGLVWULEXWLRQLQFRDO

Many inefficient operations of boilers and pulverizers were reported in coal-fired power plants in the world. One of the common causes of this inefficiency was due to inefficient operation of pulverizers when coarse coal is allowed into boiler furnace for combustion. These coals are transported into boiler …
