Mkanda woyenda pansi ndi mtundu wa mpira wopanda kanthu womwe umatha kuyandama pamwamba pa madzi. Ndi woyera imvi, wokhala ndi makoma owonda komanso opanda kanthu, komanso wolemera kwambiri. Kulemera kwa unit ndi 720kg/m3 (wolemera), 418.8kg/m3 (wopepuka), ndipo kukula kwa tinthu tating'onoting'ono ndi pafupifupi 0.1mm. Pamwamba pake ndi potsekedwa komanso posalala, ndi kutentha kochepa komanso kukana moto kwa ≥ 1610 ℃. Ndi chinthu chabwino kwambiri chosunga kutentha chomwe chimachepetsa kutentha, chomwe chimagwiritsidwa ntchito kwambiri popanga zinthu zopepuka zotayidwa komanso kuboola mafuta. Kapangidwe ka mankhwala ka mkanda woyandama makamaka ndi silicon dioxide ndi aluminium oxide. Uli ndi mawonekedwe a tinthu tating'onoting'ono, topanda kanthu, topepuka, mphamvu yayikulu, kukana kuvala, kukana kutentha kwambiri, kukana kutentha, kukana kutentha, kukana kukana moto komanso kukana moto. Ndi chimodzi mwa zinthu zopangira zomwe zimagwiritsidwa ntchito kwambiri mumakampani olimbana ndi moto.

Kapangidwe ka mikanda yoyandama: Malo opangira magetsi opangidwa ndi malasha nthawi zambiri amapera malasha kukhala ufa wa malasha ndikuupopera mu ng'anjo ya boiler yopangira magetsi, zomwe zimapangitsa kuti ayimitsidwe ndikuwotchedwa. Zinthu zambiri zomwe zimayaka moto za malasha (carbon ndi organic matter) zimawotchedwa, pomwe zinthu zosayaka moto za dothi (silicon, aluminiyamu, chitsulo, magnesium, ndi zina zotero) zimayamba kusungunuka kutentha kwa madigiri 1300 Celsius mu ng'anjo, ndikupanga thupi logwirizana la galasi la quartz ndi mullite.

Gwero la mikanda yoyandama ya phulusa la ntchentche
Mikanda yoyandama ya phulusa louluka imatanthauza ma microspheres opanda kanthu agalasi okhala ndi kuchuluka kochepa kuposa madzi mu phulusa louluka, omwe ndi mtundu wa tinthu tofanana ndi tinthu tating'onoting'ono ta phulusa louluka ndipo amatchedwa kuti amatha kuyandama pamadzi. Kupanga kwake kumachitika pamene ufa wa malasha umatenthedwa mu boiler ya chomera chamagetsi chotentha, dongo limasungunuka kukhala madontho ang'onoang'ono, omwe amazungulira mwachangu kwambiri chifukwa cha mpweya wotentha wosasunthika mu ng'anjo, ndikupanga bwalo lozungulira la aluminiyamu ya silicon. Mipweya monga nayitrogeni, haidrojeni, ndi carbon dioxide yopangidwa ndi kuyaka ndi kusweka imakula mwachangu mkati mwa bwalo losungunuka la aluminiyamu ya silicon yotenthedwa kwambiri, ndikupanga thovu lagalasi lopanda kanthu pansi pa mphamvu ya pamwamba. Kenako amalowa mu flue kuti azizire mwachangu ndi kuuma, ndikupanga ma microspheres opanda kanthu agalasi lopanda kanthu, omwe ndi mikanda yoyandama ya phulusa louluka.

Mikanda yoyandama ya phulusa la ntchentche imachokera ku phulusa la ntchentche ndipo ili ndi makhalidwe ambiri ofanana ndi phulusa la ntchentche. Komabe, chifukwa cha kapangidwe kake kapadera, imagwira ntchito bwino kwambiri poyerekeza ndi phulusa la ntchentche. Ndi ufa watsopano wopepuka wopanda chitsulo ndipo umadziwika kuti ndi zinthu za nthawi ya mlengalenga.
