CwS(coal-water slurry is a newsubstitute for oil-fuel which has been widely used. In this paper the sulfur release, parameters of desulfurization(temperature, Ca/S ratio ), particulate emission and so on were studied during CwS combustion. Compared with thedesulfurization during PC(pulverized coal)combustion, the desulfurization during Cws combustion has a high soremoval efficiency. The results prove that the desulfurization during CWS combustion is a good method of desulfurzationKeywords: pulverized coal; coal-water slurry combustion; desulfurization可f‰f‰￠,,,0-‰二~元-之2,罪O七%f‰豐T‰s.·f^%申20「正。f‰≤1.1oflt中國煤化工d“f￥0e--。%CNMHG、‰乙f‰<二豐。十之十:1999-08-02%方數(shù)據(jù)969-)Cs Goff§6。f七y.,f》科1-%22千-(f5(%)350C。f,,%量Nf…,O2「.十|51.423.852.550.864.632.8633.829中…豐1[ma8126.370.971.1730.326.2“科“世(%空氣預處理裝置96.900.02.04庫侖積分儀電解樂B一可燃燒攪拌器庫侖沮控儀。gf,%豐,豐‰B3T=1200C),。-%<2豐“,豐,豐(o,O4)》0,豐(ab,AB)%T豐;十s≤20.25MW2/f‰<."Ef‰豐0.25MW一2/f‰….°豐fi%0十■一>-￠豐⑧只.%,,一豐2/‰“:f扦“f,%,B.2.。-煤粉%oFsfI煤槳豐“‰O)2求壇,0MS2000↓.(;0-(SEM),十→-不FAM…軍之十老》-。-‰豐,豐科f-.2壓縮空氣‰i煙氣分析油槍插口次風卻灰取樣煙氣分十‰T.4/^‰水冷除塵器溫度測點水冷十干5(1400C)燃盡室風盡室M度測點中℃.20%),W、嗩噴水點灰取樣而””「科,…三士灰取樣干溫度測點中國煤化工,二Q%CNMHG、‰‰十—0…-‰。,,°%ng,>一忌2000~「%。:f%1000C)>,‰,∈aO‰A2.4f%<-豐‰6。>5為68乙酊.2f‰2m~0.3gm8),C,-%∴-邪十s正≤-千CaSO4-‰阝:「,,>fs-f正「年f‰s十>,》7%∈”…”)“55元…%,f‰<‰6%1,Fe_fi2十f%≤豐THIfi T"o士?十∴FAM∑‰軒,a/S=1.5,1200C“°二.f2f‰·》‰十%BT172C‰》‰B∑酊“8.9454%),fi%02>>34.80‰一》-%G￡“4.76T"200C,%十-十》,“{m,「225.09m。乙>“f‰x‰之一∑fi %cA。十。”,≥、們%‰己∑干之》”≤≥煤漿CaS=1.5∑·」>刮--‰?！辍甘忝簼{Ca/S=3煤粉1CS=2∑”,f‰》E「115012501350%-…‰L∑T/℃,-2CaCO3￡5 Ill安二一2.3Ca/S-%乙中國煤化工士s長a/S一SBCNMHG辶豐,Ca/SSO2eaO‰-￥辶豐:f%>元∑f‰CacO3一§B..十》,「B十;x‰,Ca/S--厙,A§610f→》-k1000-丌f‰3‰E十,豐辶十L十0+:一→0豐,W[1] Falkenberry, SO Removal by Limestone Injection [J].
