Ahkyak ai solid fuel hte chemical raw material langai hku nna, lignite gaw lai wa sai shaning ni hta mungdan kata hte maigan mungdan ni a gat lawk ni hta grai law hkra myit lawm wa ai, hpa majaw nga yang, shi a laklai ai tsi mawan ni hte bungli galaw ai lam law law a majaw re. Ndai laika hta lignite a arawn alai hte n-gun, tsi mawan hte kaga hpaji ni hta jai lang ai manu ni hpe tsi mawan ni a ningmu hku nna sawk sagawn na re.
Linite gaw nbung n shang ai masa hta npu na nhprang wan sau (600 degree-900 degree) hpe n-gun n rawng ai hku hka ja ai hku nna lu la ai ngang kang ai arung arai langai mi re. Shi a chemical nsam gaw n-gup magap hte hka lim ai masa ni hte grai ni htep ai. Lignite a madung daw ni gaw, n-gun n rawng ai carbon, n-gun n-gun, n-gun hte hka lim ai lam ni lawm ai, dai ni hta, n-gun n rawng ai carbon gaw, 70%-85% lapran hta, n-gun grau law ai, n-gun rawng ai nhprang wan hta grau law ai. Dai n-gun ja ai carbon n-gun gaw lignite hpe grau tsaw ai calorific manu hpe jaw ya ai, madung hku nna 5500-7000 kcal/kg lapran na manu hpe jaw ya ai majaw, grai kaja ai wan sau galai shai ai lam rai nga ai.
Dai n-gun n rawng ai lam gaw, lignite a kaga ahkyak ai lam langai mi rai nga ai, law malawng gaw 8%{8}}15% lapran, shinggyim masha ni a nhprang wan sau hta grau yawm ai (20%-40%). Ndai feature gaw lignite hpe wan hkru ai shaloi wan hkut n law ai hte grup yin hpe grau hkra machyi shangun ai. Dai hta n-ga, lignite a nhprang arai ni gaw raw materials hte process ni hta hkan nna shai hkat ai, madung hku nna 6%-12%, n-gun ja ai lignite nkau mi a ash hpe 8% a lawu de hkang lu ai. Ash n-gun n law ai gaw, n-gun ja ai, tsi hpaga lam hte kaga lam ni hta shi a jai lang ai atsam hpe grau kaja hkra galaw ya lu ai.
Lignite a sulfur n-gun gaw, madung hku nna n law ai, law malawng gaw 0.3%{2}}0.8% lapran na re ai hpe sadi ra ai, dai gaw, n-gun ja ai nhprang wan hta grau kaja ai. Ndai lam gaw, wan wut ai wan wut ai hte n-gang galaw ai zawn re ai hpaga lam ni a matu kaja dik ai wan sau langai mi rai nga ai, sulfur dioxide dat dat ai lam hpe atsawm sha shayawm ya lu ai. Dai aten hta, lignite hta hydrogen law law nga ai (4%-6 daram) hte n-gun amyu myu law law nga ai, dai gaw nhprang wan sau hpaga lam a matu ahkyak ai raw material basis hpe jaw ya ai.
Application madang hta, lignite gaw calcium carbide galaw shapraw ai lam hta ra kadawn ai lam ni law wa ai, ferroalloy smelting, hte mung shawa san seng ai wan sau ni gaw shi a n-gun n law ai, sulfur n law ai, calorie manu kaba ai majaw re. Htingbu htingbyen ni hpe makawp maga ai tara ni hpe ngang ngang jum tek da ai majaw, tsaw ai{1}}} mung, htunghking wan sau ni hpe lignite hte kalang ta galai shai kau ya nna, mungkan ting na gat lawk gaw dai hpe grai myit maju jung wa sai.
Lignite a chemical composition gaw grup yin hpe makawp maga ai lam hte n-gun ja ai lam a lahkawng lang akyu ni hpe jaw ya ai, n-gun galai shai ai lam hte hkai sun galaw ai lam hta rawt jat galu kaba wa ai lam hta grau grau ahkyak ai lit hpe gun hpai nga ai.
