In order to compare the particle formation characteristics of typical high-alkali and high-chlorine Xinjiang coal under combustion conditions, a three-stage high temperature drop tube furnace was used to carry out the combustion experiment of Zhundong coal (ZD) and Shaerhu coal (SEH) in air atmosphere. The characteristics of particulate matter after combustion were analyzed. Particulate matters were collected by Dekati low pressure impactor+ (DLPI+) and the mass-based particle size distribution, elemental compositions and morphology were discussed. The results showed that the particulate matter produced by the combustion of the two coal samples presents a double-peaked model. The fine particle yield of SEH is significantly higher than that of ZD. The main components of sub-micron particles were Na and Cl. The Cl in PM10 accounts for 11.8% and 28.9% of the Cl content in ZD and SEH raw coal, and Na accounts for 2.66% and 7.53% of the Na content in ZD and SEH coal ash. High levels of alkali metals and Cl promoted the formation of fine particles. A large amount of Cl in SEH raw coal migrated into particles and contributed greatly to the formation of sub-micron particles.

为比较新疆地区典型高碱煤和高氯煤在燃烧条件下颗粒物生成特性,采用三段式高温沉降炉系统开展在空气气氛下燃烧准东煤和沙尔湖煤的实验,分析燃烧后颗粒物特征。采用Dekati低压撞击器(Dekati low pressure impactor+,DLPI+)进行了颗粒物的分级收集,对其质量粒径分布、元素分布特性以及颗粒物微观形貌进行了讨论分析。结果表明:2种煤样燃烧生成的颗粒物均呈现双模态分布,沙尔湖煤的细颗粒物产率明显高于准东煤;细模态颗粒物的主要成分是Na和Cl,准东煤与沙尔湖煤产生的PM10中的Cl占原煤中Cl质量的11.8%和28.9%,Na占煤灰中Na质量的2.66%和7.53%;高含量的碱金属和Cl会促进细颗粒物生成,沙尔湖原煤中的Cl大量迁徙进入颗粒物中,对细模态颗粒的生成贡献较大。

为比较新疆地区典型高碱煤和高氯煤在燃烧条件下颗粒物生成特性,采用三段式高温沉降炉系统开展在空气气氛下燃烧准东煤和沙尔湖煤的实验,分析燃烧后颗粒物特征。采用Dekati低压撞击器(Dekati low pressure impactor+,DLPI+)进行了颗粒物的分级收集,对其质量粒径分布、元素分布特性以及颗粒物微观形貌进行了讨论分析。结果表明:2种煤样燃烧生成的颗粒物均呈现双模态分布,沙尔湖煤的细颗粒物产率明显高于准东煤;细模态颗粒物的主要成分是Na和Cl,准东煤与沙尔湖煤产生的PM10中的Cl占原煤中Cl质量的11.8%和28.9%,Na占煤灰中Na质量的2.66%和7.53%;高含量的碱金属和Cl会促进细颗粒物生成,沙尔湖原煤中的Cl大量迁徙进入颗粒物中,对细模态颗粒的生成贡献较大。

In order to compare the particle formation characteristics of typical high-alkali and high-chlorine Xinjiang coal under combustion conditions, a three-stage high temperature drop tube furnace was used to carry out the combustion experiment of Zhundong coal (ZD) and Shaerhu coal (SEH) in air atmosphere. The characteristics of particulate matter after combustion were analyzed. Particulate matters were collected by Dekati low pressure impactor+ (DLPI+) and the mass-based particle size distribution, elemental compositions and morphology were discussed. The results showed that the particulate matter produced by the combustion of the two coal samples presents a double-peaked model. The fine particle yield of SEH is significantly higher than that of ZD. The main components of sub-micron particles were Na and Cl. The Cl in PM10 accounts for 11.8% and 28.9% of the Cl content in ZD and SEH raw coal, and Na accounts for 2.66% and 7.53% of the Na content in ZD and SEH coal ash. High levels of alkali metals and Cl promoted the formation of fine particles. A large amount of Cl in SEH raw coal migrated into particles and contributed greatly to the formation of sub-micron particles.

新疆煤炭是一种极具潜力的能源,储量巨大,占我国煤炭储量的近40%[1],且开发条件相对优越,具有广阔的开发利用前景[2]。近年来,新疆准东、哈密等地区发现的煤中Na、Ca等碱金属及碱土金属的含量均高于我国其他地区的动力用煤,部分煤种还具有高氯的特点,在燃用过程中出现严重的锅炉结渣和尾部受热面沾污积灰现象,大大限制了其应用[3-4]。在煤基质中,碱金属和碱土金属(alkali and alkaline earth metal,AAEM)主要以水溶性和可交换离子的形式存在。高温条件下,AAEM蒸气通过冷凝成核等方式形成细颗粒物[5]。而煤中的Cl质量分数在超过0.25%时,其燃烧产生的烟气及颗粒物(PM)会造成金属设备的腐蚀,同时释放到烟气中的Cl也加剧了环境污染[6]
现有研究表明,燃料中高含量的Cl元素可以显著促进细颗粒物的形成[7],富含Cl和AAEM的气溶胶在冷凝和成核后加剧了受热面的沉积、结渣和腐蚀[8-9]。排放到大气中的燃煤颗粒物粒径小,比表面积大,易附带有毒、有害物质(重金属、微生物等),对人体健康和环境有严重危害。颗粒物生成过程与煤中矿物质的赋存形态以及燃烧条件密切相关。曾宪鹏等[10]在空气气氛下研究不同燃烧温度时燃煤细颗粒物的生成特性,结果表明当燃烧温度升高时,细颗粒物中的Mg和Ca含量增加,Na和S含量减少。徐义书等[11]在掺混有不同浓度HCl的模拟空气中研究3种准东煤燃烧后颗粒物的形成机制,结果表明HCl促进了NaCl形式矿物蒸气的形成,进而促进成核形成超细颗粒物。Li等人[12]研究了准东煤在25 kW自稳燃烧炉燃烧过程中细颗粒的形成,其结果表明PM0.4主要由硫酸钠组成,随着粒度的增大,铝硅酸盐成为细颗粒的主要成分。阮仁晖等[13]研究了新疆准东高碱煤、准南低碱煤及混煤在燃烧过程中细颗粒物的排放特性。发现低碱煤燃烧产生的细颗粒物量明显减少,同时发现Ca、Fe在混烧降低PM10过程中具有重要作用。前期研究重点关注了煤中碱及碱土金属对燃煤颗粒物的生成特性影响,而对煤中同时存在高碱及高氯特征的沙尔湖煤和高碱准东煤在燃烧过程中颗粒物生成特性对比的研究较少。Na和Cl在煤燃烧过程中的迁移率对研究细颗粒物的形成机理具有重要意义,在煤燃烧过程中,高碱及高氯特征对细颗粒物的生成均有促进作用。前期重点关注分析了Na的作用。
本文在前人研究的基础上,对Na和Cl的释放以及迁移进入颗粒物中的含量做了更加细致的定量分析,为高碱高氯煤的高效清洁利用提供参考。
本文选取了典型的高碱煤(准东煤)和高氯煤(沙尔湖煤)在高温沉降炉系统上进行空气气氛下的煤燃烧实验。实验采用Dekati低压撞击器(Dekati low pressure impactor+,DLPI+)对燃烧后颗粒物分级取样,研究了颗粒物的质量产率粒径分布、颗粒物元素分布特性和微观形貌,对比了高碱和高氯煤中Na、Ca、Cl、S等元素对细颗粒物生成特性的影响,对Na和Cl的释放和迁移特性做了定量分析。
准东煤(ZD)和沙尔湖煤(SEH)2种煤样的工业分析和元素分析见表1,煤灰成分分析见表2
煤样经过干燥、破碎和筛分,粒径达到100 μm以下。由表1可见,SEH中Cl质量分数为0.485%,是ZD的5倍以上。由表2可见:2种煤样灰分中Na2O质量分数均超过4%,其中ZD灰中Na2O为8.49%,SEH为4.32%,2种煤均属于高碱煤;与此同时,2种煤灰中CaO的质量分数相近,均在32%左右;ZD灰中SiO2和Al2O3低至7.88%和5.22%,SO3质量分数较SEH更高,达到21.59%。
本实验采用三段式高温沉降炉系统进行煤燃烧后颗粒物取样分析,如图1所示。炉管采用3段长度相同的99%刚玉管连接而成,可耐受1 300 ℃的高温。3段刚玉管的接缝处使用高温胶粘结,可以保证在连接处具备较好的密封性。刚玉管内径为50 mm,炉膛恒温区长度约60 cm。
沉降炉顶部布置有给料系统,给料系统由自行设计的微量振动流态化给粉装置、水冷给粉管、供气系统组成。煤粉由1.5 L/min的一次风携带,通过水冷下料管将煤粉投放至炉膛恒温区。给煤量约为280 mg/min。二次风由下料管与反应器的间隙中送入,流量为3 L/min。一、二次风均为空气。2种煤燃烧时其过量空气系数在3.2左右,较大的过量空气系数可以保证煤粉完全燃烧[14]。为确保实验数据的可靠性,每组实验重复3次。煤粉燃烧后的颗粒物通过水冷取样管取样。为了防止颗粒物发生聚集,取样的同时通入10 L/min的N2淬冷并稀释烟气。取样管出口烟气通过旋风分离器分离空气动力学直径大于10 μm的飞灰,随后烟气进入DLPI+进行颗粒物粒径分级。空气动力学直径为D50(μm)的颗粒的捕获效率为50%。DLPI+第1—14级撞击基板的D50分别为0.015 6、0.030 3、0.054 1、0.094 3、0.154 0、0.254 0、0.380 0、0.600 0、0.943 0、1.620 0、2.460 0、3.640 0、5.340 0、9.840 0 μm,在DLPI+装置内的颗粒物收集基底的铝箔片表面涂抹松脂(Apiezon-H润滑脂),以捕集燃烧后颗粒物。为避免降温对颗粒物取样的影响,取样过程采用加热套的方式对取样枪、分离器及DLPI+各段管道进行实时加热保温,保温温度为120 ℃。沉降炉燃烧区炉膛温度为1 100 ℃,颗粒物取样点烟气温度为600 ℃。
通过高精度天平(德国 赛多利斯MSA6.6S,精度为0.001 mg)称量实验前后的铝箔片质量,获得收集到的颗粒物质量。将收集到的颗粒物进行扫描电子显微镜-能谱仪(荷兰飞纳Pure Plus)测试,分析颗粒物元素。
图2为2种煤燃烧后颗粒物质量-粒径分布。
图2可以看出,燃烧生成的颗粒物均呈现双模态分布,ZD细模态颗粒与粗模态颗粒过渡点的颗粒物粒径在0.2 μm处,而SEH过渡点颗粒物粒径为0.4 μm。SEH在亚微米粒径范围内的质量峰位于0.030 μm处,峰值为0.630 mg/g(以单位质量的煤计,下同);在超微米粒径范围内的质量峰位于2.459 μm处,峰值为4.822 mg/g。ZD在亚微米粒径范围内的质量峰位于0.054 μm处,峰值为0.023 mg/g;在超微米粒径范围内的质量峰位于2.459 μm处,颗粒物产率为0.119 mg/g。一般认为,亚微米颗粒的形成主要与相应成分气化、成核和凝结过程有关,随着成核形成的纳米级颗粒浓度的增加,蒸气饱和度逐渐降低,此时大量的无机蒸气(特别是易气化的碱金属)会以这些颗粒为核心,在其表面发生异相凝结。凝结不会影响颗粒数目,但会增加颗粒粒径[15]。根据表2的灰成分来看,ZD比SEH具有更多的碱金属Na,这可能是ZD比SEH的亚微米范围内峰值粒径更大的原因。2种煤在超微米粒径范围内质量峰值的粒径相同,SEH的颗粒物产率整体高于ZD。
为了说明2种煤的细颗粒物生成特征,绘制了DLPI+14个撞击基板上的PM10的元素组成。C和O不是研究的重点,去除这2种元素可以避免松脂的影响。燃煤产生的PM10主要由Fe、Ca、K、Cl、S、P、Si、Al、Mg和Na等元素组成。图3给出了ZD和SEH燃烧产生的PM0.4的元素组成。PM0.4主要由Na、Mg、Ca、Fe、S、Cl组成。从第1级(D50=0.015 6 μm)到第6级(D50=0.254 0 μm)颗粒物的元素组成中,SEH和ZD中的Na和Cl质量分数总和分别大约在80%和70%,其中SEH中Cl质量分数较ZD高了约10%。随着颗粒物粒径的增大,Na、Cl的质量分数呈下降趋势,而Ca的质量分数逐渐升高。Si、K、Mg、Al的总质量分数较低,在每一级上都不超过10%。ZD中S在每一级约占10%,而SEH几乎不含S,这是由于ZD原煤和灰中的S质量分数高于SEH。煤中碱金属和碱土金属在高温燃烧过程中,易气化挥发,通过成核、冷凝、团聚等机制转化为PM0.4。Na、K、S的气化程度最强,但根据煤的灰成分分析,K的质量分数很低。Fe、Ca、Mg的气化程度中等。Fe元素主要通过离子交换态Fe元素的挥发、含铁矿物的氧化或分解转化为PM0.4。元素Si和Al的气化程度很低,特别是Al,质量分数不超过5%。
图4为ZD和SEH燃烧产生的PM0.4~10的元素组成。
由于PM0.4~10的形成机制主要包括焦炭或矿物质的破碎和聚结[16],因此其元素组成(尤其是PM1~10)与原煤灰分的元素组成较为接近。PM0.4~10主要由Si、Al、Ca和Fe组成,占9种无机元素质量的65%~85%。由于PM0.4~10元素组成受粒径影响较小,其中的Na、Cl元素的质量分数显著低于PM0.4,Na、Cl元素的质量分数随粒径的增大而减小,Ca、Si元素的质量分数随粒径的增大而增大。
为更清晰地阐明颗粒物中主要无机元素与颗粒物尺寸的关系,采用摩尔比的方法[12]对ZD和SEH中的[2x(Ca)+2x(Mg)+x(Na)+x(K)]/[2x(S)+x(Cl)]进行计算,以便对颗粒物形成机制进行分类[17]。其中,x代表元素的摩尔分数,其摩尔比随粒径的变化曲线如图5所示。
图5可以看出:当颗粒粒径小于0.4 μm时,摩尔比基本不随颗粒粒径变化;颗粒粒径大于0.4 μm时,摩尔比开始增加。这表明颗粒成分在0.4 μm发生变化。已有研究表明,0.4 μm是颗粒成分发生明显变化的转折粒径[18]。当粒径小于0.4 μm时,[2x(Ca)+2x(Mg)+x(Na)+x(K)]/[2x(S)+x(Cl)]的值为1~2;特别对于SEH而言,上述摩尔比保持在1左右,这说明氯化物和硫酸盐是在该模式下的主要成分。但当粒径大于0.4 μm时,摩尔比会迅速增大,显示出与Si、Al质量分数相同的增加趋势,说明此粒径范围的主要成分是硅酸盐和铝硅酸盐。同时也表明,PM0.4的形成机理与PM0.4~10有很大的不同。Ruan[14]和Li[12]的研究均发现,0.4 μm是[2x(Ca)+2x(Mg)+x(Na)+x(K)]/[2x(S)+x(Cl)]摩尔比的转变点。
图6为PM10x(Cl)/x(S)摩尔比与粒径的关系。
SEH燃烧产生的颗粒物中Cl的质量分数远大于S的质量分数,而ZD燃烧产生的颗粒物中S的质量分数比SEH高,Cl的质量分数比SEH低。对于SEH,Na和Cl是PM0.4的主要元素组成,Na和Cl的摩尔比约为1,表明SEH的PM0.4成分主要为NaCl,这由图5的摩尔比也可以得到验证。对于ZD,Na、Cl和S是PM0.4的主要元素组成,因此ZD的PM0.4的主要成分可能是NaCl和Na2SO4
各级基板上Cl、Na、S的绝对质量产率如表3所示。Cl在ZD与SEH产生的PM10中的总质量产率分别为0.099 2 mg/g和1.402 7 mg/g,分别占原煤中Cl质量的11.8%和28.9%,可见SEH中Cl更多地迁徙进入微细颗粒物中。S在ZD与SEH产生的PM10中的总质量产率分别为0.110 0 mg/g和1.262 1 mg/g,分别占原煤中S元素质量的31.6%和9.17%,这是由于ZD原煤中S元素质量分数更高。Na在ZD与SEH产生的PM10中的总质量产率分别为0.030 8 mg/g和0.063 6 mg/g,分别占煤灰中Na质量分数的2.66%和7.53%,与Cl特征相似。综上,当煤同时具备高碱及高氯特征时,燃烧后更容易生成细颗粒物。
图7给出了DLPI+撞击基板第3级(D50=0.094 3 μm)、第7级(D50=0.380 0 μm)、第9级(D50= 0.943 0 μm)以及第11级(D50=2.460 0 μm)颗粒物的微观形貌。
图7可见,ZD与SEH燃烧生成的亚微米颗粒基本上都是球形颗粒。由前面的讨论可知,这些亚微米颗粒主要由煤中矿物质的气化、成核、凝结及凝聚等过程形成,在表面张力的作用下,通过气化—凝结机理形成的颗粒基本上呈球形。第3级和第7级基板的颗粒形貌呈白色絮状。根据能谱分析,这些颗粒主要含Na、Cl 2种元素,可推断其成分主要是NaCl。在第11级基板上,收集到的颗粒物绝大多数是球形颗粒。通过能谱分析,这种光滑的球形颗粒含Si、Al较多,可能是铝硅酸盐。其余的少量颗粒形状不规则,可能是煤中矿物质在高温下熔融后冷却形成的。同时,可以观察到有一些大颗粒上粘附着一些细小颗粒,这也说明细小颗粒在大颗粒上聚结可能是大颗粒生长的主要途径之一。
本文对高碱准东煤和高碱高氯沙尔湖煤进行颗粒物生成特性研究,得出了以下结论:
1)沙尔湖煤的颗粒物质量产率比准东煤高1个数量级。沙尔湖煤的细模态峰值粒径为0.03 μm,峰值为0.630 mg/g;准东煤的峰值粒径位于0.054 μm处,峰值为0.023 mg/g。准东煤与沙尔湖煤的粗模态峰值粒径均在2.459 μm处,颗粒产率分别为0.119 mg/g和4.822 mg/g。
2)2种煤燃烧后颗粒物元素组成相差不大。PM0.4的主要成分均为NaCl,Na和Cl对细模态颗粒物生成贡献较大;PM0.4~10的主要元素为Ca和Si。煤中高质量分数的Cl促进了细颗粒物的形成。
3)准东煤与沙尔湖煤产生的PM10中的Cl分别占原煤中Cl质量的11.8%和28.9%,Na分别占煤灰中Na的2.66%和7.53%。当煤同时具有高碱及高氯特征时,燃烧后更容易生成细颗粒物,建议在燃烧前通过水洗等方式去除煤中的Cl和Na。
