Abstract

本发明涉及一种工业型煤，它以烟煤煤泥和无烟煤煤泥为原料，添加固硫剂CaO制作而成。各成份的重量百分比为：烟煤煤泥60-70%，无烟煤煤泥20-30%，固硫剂CaO8-10%。将原料掺配粉料，添加水份搅拌后挤压成型，经干燥后成为成品。该型煤将烟煤煤泥粘结性好和无烟煤煤泥发热量高的特点充分结合，生产的型煤产品强度高，防水性好，SO2排放削减量显著，价格低廉，易于推广应用。

Description

一种工业固硫洁净型煤
本发明属于固体燃料领域，特别涉及一种工业型煤。
现有的工业型煤产品，有几种类型：一种是将块煤粉碎后加工成型，工艺复杂、成本高；一种是单一的煤泥成型，如以烟煤煤泥为原料，其发热量低，无法满足工业锅炉要求；如以无烟煤煤泥为原料，由于无烟煤粘结性差，必须掺加大量粘结剂，增加了型煤成本，限制了型煤产品的推广普及。
本发明的目的是以烟煤煤泥和无烟煤煤泥为原料，将烟煤煤泥粘结性好和无烟煤泥发热量高的特点充分结合，从而生产出一种可满足工业及民用锅炉燃煤要求的固硫洁净型煤。
本发明的技术方案是这样的：该型煤以煤泥为基本原料，添加固硫剂CaO制作而成。各成份重量百分比为：烟煤煤泥60-70％，无烟煤煤泥20-30％，固硫剂CaO 8-10％。该型煤的制作工艺为：原料配掺粉料→添加水份搅拌→挤压成型→干燥→成品。该型煤的最佳成型水份为20-25％，挤压成型的压力为7×106Pa，可保证型煤产品的机械强度。
该型煤能显著降低SO2排放量，燃用本发明的型煤在相同条件下与燃用其它煤种相比，其SO2排放削减量在50％左右。该型煤强度高，防水性好，价格低廉，易于推广应用。
本发明的实施例如下：
实施例一：取烟煤煤泥65％，无烟煤煤泥25％，固硫剂CaO 10％，添加水份搅拌均匀，在成型水份25％，压力为7×106Pa条件下挤压成型，经干燥后成为成品。
实施例二：取烟煤煤泥70％，无烟煤煤泥20％，固硫剂CaO 10％，添加水份搅拌均匀，在成型水份20％，压力为7×106Pa条件下挤压成型，经干燥后成为成品。
二实施例制成的型煤成品干燥后水份<3％，跌落强度>80％。经用KZL2-8锅炉试烧，出口SO2浓度(mg/Nm3)为265mg/Nm3，与原烧煤种相比，SO2排放削减量为48％。
