摘要
采用一维试验炉和着火试验炉,对2种印尼煤与大同煤、准格尔煤、神华煤、平朔煤、兖州煤进行掺烧试验研究,分析其掺烧特性。结果表明:2种印尼煤的着火温度较低,属于极易燃烧煤种,与国内煤掺烧时,可以降低国内煤活化能,从而改善国内煤着火温度;2种印尼煤燃尽率均较高,低热值印尼煤不宜与低挥发分煤种掺烧,高热值印尼煤掺烧时,燃尽率与掺烧比例存在最优值;2种印尼煤都有较强的结渣倾向,掺烧低结渣倾向煤种可以有效改善其结渣状况。
On a one-dimensional furnace and ignition furnace form TPRI,blend burning tests of two Indonesian coals and Datong coal、Zhungeer coal、Shenhua coal、Pingshuo Coal、Yanzhou Coal were carried out.Moreover,the co-firing characteristics of the coal mixtures were analyzed.The results show that：the two Indonesian coals have low ignition temperature,which are easy to burn;when co-fired with the domestic coals,the two Indonesian coals can reduce the activation energy of the domestic coals,thus to improve the coal mixtures＇ ignition temperature;the two Indonesian coals have high burnout rate,Indonesia coal with low calorific value should not be co-fired with the low volatile coal;the Indonesian coal with high calorific value exists the optimum burnout rate and blending proportion when co-combusted;both the two Indonesian coals have a strong slagging tendency,so being co-fired with coals have low slagging tendency can effectively reduce the mixtures＇ slagging property.
