一种无土煤球粘结剂及其制备方法
摘要：
本发明涉及一种无土煤球粘结剂，它包括下列重量份比的成分：含腐殖酸的褐煤30-38份，氢氧化钠1-5份，水60-65份。该种粘结剂使煤球粘结能力增强，并且煤球强度由60公斤压力的承受度提高到了70公斤，节省了膨润土还使煤球中的固定碳由66％提高到了68％，增强了造气掺烧的适应性。
摘要（英）：

The invention relates to a clay-free coal ball binder. The clay-free coal ball binder comprises the following components in part by weight: 30 to 38 parts of humic acid-containing lignitic coal, 1 to 5 parts of sodium hydroxide and 60 to 65 parts of water. The binder enhances the binding capacity of coal balls; the strength of the coal balls is improved to 70kg from 60kg; bentonite is saved; fixed carbon in the coal balls is improved to 68 percent from 66 percent; and adaptability of gas making mixed combustion is enhanced.
