摘要
将洞口和平煤分别与邵阳岩头岭、武冈龙坪老矿煤在不同配比下得到的混煤在STA449F3型热重分析仪中进行热重实验,利用热重分析法对两种不同掺烧方式下的混煤进行燃烧特性实验研究,分析两种掺混方式下混煤的着火温度和可燃性,并对其燃尽特性和综合燃烧特性进行研究.研究结果表明,各混煤的着火特性、燃烧特性和综合燃烧特性都是随着易着火煤种比例的增加而有所改善.通过对各项性能的分析,确定了混煤的最佳掺配比.
The thermogravimetric experiments study on blend coals composed of DongKou- HePing blended with the coal of ShaoYangYanTou and the coal of WuGangLongPing in dif- ferent ratios respectively. Because of the different components of the blended coals, the re- search for combustion characteristics of blended coals is necessary. The thermogravimetric plots-differential thermal analysis（TG-DTG） on lignite, anthracite and its blended coals which are often used in the power plant were carried out. And two different modes blended coals＇ ignition temperatures, burnout temperatures were discussed. Combustible indexes, combustion characteristic indexes and steady combustion indexes were compared. The re- suits show that blended coals have improved ignition characteristics, combustion characteris- tics and determine the optimal blending ration.
