Abstract

本发明的上点火型煤,采用劣质烟煤或煤泥与矸石为主原料,其中上点火炭由硝酸盐类,碳素,焦粉,粘结剂组成,常温下混合压制成炭饼做为上点火层引燃型煤,型煤由劣质烟煤和矸石经过粉碎,碾压,成型等工艺制成。本发明的型煤具有上火时间快,燃烧热值高,破碎率低,燃烧充分,污染小的特点,由于利用劣质烟煤和矸石,变废为宝充分利用资源,对于国民经济具有重大意义。

Description

本发明涉及一种固体燃料,特别是涉及一种由不同的原料层组成的型煤。
现有型煤,如蜂窝煤大多采用优质无烟煤为主要原料,这种型煤点火困难而且热效率低。CN1034750A公开了一种上点火易燃炭,其主要目的是在烤肉、野炊时能提供一种使用方便的型煤,这种型煤的主要成份是不粘煤、锯末炭、生据末、烟煤、硝酸盐类及有机粘结剂。这种型煤主要是采用锯末炭和生锯末为主要成份,因此燃烧时间短,不适合家庭取暖和做饭。
本发明的目的是提供一种引燃时间短,能充分利用劣质烟煤、煤泥和矸石,而且燃烧热效率高的型煤。
本发明的型煤主要包括两个部分,一是点火层,二是主燃烧体。点火层主要由易燃材料(如硝酸盐、碳素、焦粉)加粘结剂组成。燃烧体采用劣质烟煤,煤泥及煤矸石加粘合剂组成。
本发明具有引燃速度快、无烟无味、热效率高及有利于环境保护等特点。
以下结合附图对发明做进一步说明。
图1为上点火型煤的结构示意图。
图2为本发明的工艺流程图。
参照图1,本发明的型煤包括上点火炭层和燃烧主体2。其中上点火炭1由以下配方制成:由粒度为100目的硝酸盐类3份,粒度为30目的碳素5份,粒度为30目的焦粉1.5份和粘结剂0.5份组成,常温下经混合压制成炭饼。燃烧主体2由劣质烟煤5份和矸石5份, 或煤泥5份和矸石5份以适量的黄土或废纸浆为粘合剂,通过如图2的工艺过程加工成型。
参照图2,将各5份的烟煤或煤泥与矸石通过电磁分离器除掉其中的金属杂物经粉碎机破碎至粒度为30目,混入一定量的黄土浆料或废纸浆料经混合搅拌后送入碾压机碾压以增强原料密度,再送入成型机压铸成型后干燥入库。
