Abstract:
pyrolysisandcombustioncombinedpolygenerationsystemisamoreefficientwayforligniteutilization,andcanalsoproducevarietyofvaluablepyrolysisproducts.toexplorethefeasibilityofthispolygenerationsystem,thermo？gravimetricanalysisonymligniteanddtbituminouscoalwasconducted,andthecharacteristicparametersforpyrolysis,combustion,andgasificationwereobtained.moreover,theactivationenergyofeachreactionwascalculatedbycoats？redfernmethod.theexperimentalresultsshowedthat,comparedwithdtbituminouscoal,ymlignitepyrolysisprocessstartsatalowertemperature,anditssemi？cokereactivityduringcombustionandgasificationwasbetter.inaddition,activationenergycalculationindicatedthat,theapparentactivationenergyofgasificationofbothcoalsweremuchhigherthanthatofthepyrolysis.therefore,forlignite,pyrolysisandcombustioncombinedpolygenerationsystemmayachievehigherefficiencyandbeworthyforfurtherresearch.
