Lub npe hu ua thee-dej slurry yog hais txog cov slurry ua los ntawm 70% pulverized thee, 29% dej thiab 1% tshuaj additives tom qab nplawm. Nws yog cov roj ua kua uas tuaj yeem nqus tau thiab ua rau tsis zoo li roj av. Nws tuaj yeem thauj thiab khaws cia nyob deb, thiab nws cov nqi calorific yog sib npaug rau ib nrab ntawm cov roj roj. Nws tau raug siv los hloov cov roj hluav taws xob zoo tib yam boilers, cyclone furnaces, thiab txawm tias chain-type fast-loading furnaces. Piv nrog cov thee gasification los yog liquefaction, thee-dej slurry txheej txheem yog yooj yim, kev nqis peev yog ntau dua, thiab tus nqi kuj tsawg, yog li txij li thaum nws tau tsim nyob rau hauv nruab nrab-1970s, nws tau nyiam cov xim ntawm ntau lub teb chaws. kuv lub teb chaws yog ib lub teb chaws uas tsim cov thee loj. Nws tau nqis peev ntau dua hauv cheeb tsam no thiab tau txais kev paub nplua nuj. Tam sim no nws tseem muaj peev xwm ua kom muaj siab-concentration thee-dej slurry los ntawm cov hmoov hmoov uas ua los ntawm cov thee ntxuav.
Cov tshuaj additives ntawm thee-dej slurry yeej muaj xws li dispersants, stabilizers, defoamers thiab corrosives, tab sis feem ntau xa mus rau ob pawg dispersants thiab stabilizers. Lub luag haujlwm ntawm cov khoom ntxiv yog: ntawm ib sab, cov thee pulverized tuaj yeem sib txawv hauv cov dej nruab nrab hauv daim ntawv ntawm ib qho me me, thiab tib lub sijhawm, nws yuav tsum tau tsim cov hydration zaj duab xis rau ntawm qhov chaw. particle, yog li ntawd cov thee dej slurry muaj qee yam viscosity thiab fluidity;
Ntawm ib sab, cov thee-dej slurry muaj ib qho kev ruaj ntseg los tiv thaiv cov nag lossis daus ntawm pulverized thee hais thiab tsim ntawm crusting. Peb lub ntsiab lus uas zoo CWS yuav tsum muaj yog siab concentration, ntev stability thiab zoo fluidity. Muaj ob lub hauv paus rau kev npaj cov thee-dej slurry zoo: ib qho yog cov thee zoo thiab cov khoom sib faib ntawm cov hmoov hmoov me me, thiab lwm yam yog cov khoom siv tshuaj zoo. Feem ntau hais lus, thee zoo thiab coal hmoov particle loj yog qhov ruaj khov, thiab nws yog cov additives uas ua lub luag haujlwm.
Txhawm rau txo cov nqi tsim khoom ntawm cov thee-dej slurry, nyob rau xyoo tas los no, qee lub tebchaws tau txuas nrog qhov tseem ceeb rau kev tshawb fawb thiab kev siv cov humic acid thiab lignin li additives, uas tuaj yeem tsim cov khoom sib xyaw nrog ob qho tib si dispersant thiab stabilizer ua haujlwm.
