Performance analysis of a model pulverised coal combustion system
Keywords:
Performance analysis, thermal, system, burner efficienciesAbstract
Performance analysis of a model pulverized coal combustion system is undertaken.. Performance analyses results show that the system has a maximum thermal efficiency of 46.5%, maximum system efficiency of 43%. This shows an encouraging performance when compared with the thermal efficiencies expected in the brown coal fired plants which are around 42%, and 45% for equivalent new bituminous coal fired units. Furthermore, the performance of the designed system is good when compared with some wood based fuel burners such as the improved vented mud burner (IVM) which has the thermal efficiency values across fuels that varies from 10% to 23%.
