The experimental results show that the parent coals keeptheir own individual ignition and carbon burnout characteristics in blend combustion. The pyrolysis characteristicsand activation energy of coal blends are decided by the blending rate. Meanwhile, a general combustion parametSw, which can well indicate the combustion characteristics is proposed in this paper.Keywords: coal blends pyrolysis: ignition: burnout thermogravimetric analysisAic°lo1u1 A HEEy EOEe±,l旧auEa0AxA°。iA9A0A.0uAxA0、E1、20°10EABE0B01ENex°0 Ay% EONEAUEY00°。00·E0±000iA°μAEA0100‰oDpE0NeND1.1 EONeEE00-010-ECOU3IDO i0OE TA E TA. 2aAi iroEOEA i±3A2E0AEO土% Ai NS Hc u RIGAKU8150DEEi0A11μA0006。主0·E0 Ne uAuuAcu lB31a,Aa0 0, B lADiucxeA-9iaB10EEA-。001E0EDci(4 TG CulB)。TGcu啊A(E土姬a)±61aIom 2x u// HAEEEi iB (DTG Cu iB).Eia,211)2aATA哐§:TG-DSC,E0TA1073K;TGEE-01o(DTA)i2n E%E"AeAi EE.
