Cleaning combustion and drying of coal can be contributed to improve fuel applied efficiency and reduce greenhouse gas emissions and particulates to the atmosphere. Parameters of drying, theoretical/actual air requirement and volume of flue gas of coal combustion, ignition characteristic coefficient, and burning rate were introduced in the paper. Relationships between moisture and calorific value, capacity of theoretical power generation, generator coal consumption, theoretical air volume, and flue gas emission were described in curves. The calorific value is mainly affected on elements of C and H by sensitivity analysis of drying experimental data. Equations 41 and 42 were recommended to evaluate the integrated characteristics on combustion and drying. Figure 1 shows physical property of drying coal matching with combustion and drying characteristics reflecting demands of cleaning combustion. The coupling applied technology of combustion and drying-based element analysis will benefit cleaning coal, reducing greenhouse gas emissions.
