Abstract:
The combustion performance of fuels is important in determining fuel applicability to a given combustion process. Establishment of well-defined combustion-related parameters is of particular importance in dealing with low-rank fuels such as the western subbituminous coals and lignites in both conventional pulverized and novel applications. The characterization of these fuels takes two forms: (1) the evaluation of operational performance in terms of slagging and fouling potential, carbon burnout, flame characteristics; and (2) an assessment of environmentally related parameters such as emissions of nitrogen oxides, sulfur dioxide, particulates, and trace elements. In an attempt to address these problem areas, experimental and paper studies have been conducted. Attention is focused on (1) indicating the basic features of pulverized coal fired unit design, (2) ranking of coal types, and (3) the identification of the coal-quality parameters which significantly impact power plant design and operation. In this way, the exploration geologist will be able to develop an overview of the considerations associated with the coal selection and utilization.
