Description

一种复合生物质燃料
技术领域
本发明涉及生物质燃料技术领域，尤其涉及一种复合生物质燃料。
背景技术
随着石油、煤炭等资源的日益枯竭，生物质燃料开始逐渐受到人们的重视。生物质燃料是指将生物质材料燃烧作为燃料，一般主要是农林废弃物(如秸秆、锯末、甘蔗渣、稻糠等)。是将农林废物作为原材料，经过粉碎、混合、挤压、烘干等工艺，制成各种成型(如块状、颗粒状等)的，可直接燃烧的一种新型清洁燃料。但是由于生物质燃料的紧密压缩，会导致在生物质燃料燃烧时，其内部氧气不充足，无法充分燃烧。
发明内容
基于背景技术存在的技术问题，本发明提出了一种复合生物质燃料，本发明选用适宜的助燃剂、碳酸氢钠、疏松剂相互配合，使得本发明所述的生物质燃料具有较高的燃烧效率高，其燃烧较充分，且抗跌碎性能好。
本发明提出的一种复合生物质燃料，其原料按重量份包括：生物质原料70-80份，无烟煤粉15-25份，助燃剂2-4份，发泡剂0.5-1份，疏松剂4-6份，粘结剂8-10份。
优选地，助燃剂为氧化钙和氧化铝，其中，氧化钙和氧化铝的重量比为1:1-2。
优选地，疏松剂为硅藻土、沸石和活性炭，其中，硅藻土、沸石和活性炭的重量比为1:1:2-4。
优选地，硅藻土、沸石和活性炭的粒径均为200-300目。
优选地，发泡剂为碳酸氢钠。
优选地，粘结剂为木质纤维素和糊化淀粉。
优选地，生物质原料为农作物秸秆、菌渣、木屑。
优选地，生物质原料的水含量为10-15％。
优选地，生物质原料的粒径为100目。
本发明的制备方法为：将生物质原料、无烟煤粉、助燃剂、发泡剂、疏松剂、粘结剂混匀，压缩成型制得复合生物质燃料。
有益效果：
本发明选用无烟煤粉与生物质原料相互配合，提高其燃烧性能；选用硅藻土、沸石和活性炭相互配合填充在生物质燃料中，改善生物质燃料的内部结构，增加孔隙度，并和发泡剂碳酸氢钠相互配合，使得生物质燃料在燃烧时，增加燃料内部与氧气的接触面积，促进生物质燃料充分燃烧，提高其燃烧效率；选用氧化钙和氧化铝作为助燃剂，可以进一步促进本发明充分燃烧；木质纤维素和糊化淀粉作为粘结剂，并调节生物质原料的水含量，可以使得本发明具有良好的抗跌碎等机械性能；另外硅藻土、沸石、氧化钙和氧化铝相互配合，还可以改善生物质燃料容易结渣的问题。
具体实施方式

对比例1
一种复合生物质燃料，无助燃剂、碳酸氢钠和疏松剂，其他同实施例3。
依据GB/T213-2008《煤的发热量测定方法》和GB/T212-2008《煤的工业分析方法》检测实施例1-3和对比例1，结果如下表所示：
检测项目 实施例1 实施例2 实施例3 对比例1
外观 表面光滑 表面光滑 表面光滑 表面光滑
抗跌碎强度％ 97.8 97.2 97.5 98.2
热值MJ/kg 19.0 19.7 19.4 19.9
燃烧效率％ 97.3 98.8 98.9 87.2
灰分％ 8.14 7.36 7.95 8.78
备注：抗跌碎强度的检测方法为：将待测生物质燃料从4m高的地方自由降落到光滑的水泥地上，重复10次，称量跌落前、跌落10次后的生物质燃料重量，抗跌碎强度％＝跌落前重量/跌落10次后重量*100％。
