Experimental study on the combustion and NOx emission characteristics of a bituminous coal blended with semi-coke

Combustion and NOx emission characteristics of a bituminous coal (BC) blended with semi-coke (SC) are investigated using a Thermogravimetric Analyzer (TGA) and Drop Tube Furnace (DTF) at a different SC blending ratio Xsc. TGA results show that BC and SC have similar mass loss patterns but BC-SC blends have a second trough on their DTG curves. The addition of semi-coke increases ignition and burnout temperatures of the blends, but barely affects...
