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 SOzremoval efficiency. The results prove that the desulfurization during CWS combustion is a good method of desulfurzationKeywords: pulverized coal; coal-water slurry i combustion desulfurizatic士一御f‰,f‰.,,,5一。a%°￠,,,0”‰是二~元一之2,罪O七‰豐‰5.·f^一%申20W正。,f%≤1.1科乙3<-0--。%暑「手d￥‰豐、‰E”>f‰<中…士十老十1998-10-06;1999-08-02§6f二>科§1-‰2-2千-(f1350C。己N”-….「….,暑SO2-「”一.十51,423.852.550.864.63(口%‰豐、9中豐1[4812121637097171203216242“科“一空氣預(yù)處理裝置科-傘-C00AOS02FeO96.900.780.0392.040.082庫(kù)侖積分儀電解題樂B燃燒爐?！恪！?。攪拌器庫(kù)侖溫控儀‰f,%」豐,豐‰阝-.3(T=1200C)。-‰<82%豐"豐,十O,豐(o,O4)2>8.+(ab,AB)‰「:→0,豐1.20.25MWz/f0.25MW^/f%豐f只.‰是,,-“豐口“2/~>￠豐-育計(jì)f,%,阝.2煤粉%oFs fl十究一煤槳,,0MSI20005((SEM),十15020025>-κTAM軍乙十老>-列一之￠豐3豐,豐科f-.2壓縮空氣煙氣分析油槍插口而暑》5;…小一冷水飛灰取樣風(fēng)溫度測(cè)點(diǎn)煙氣分個(gè)除塵器十豐只,?！?十千一2,,%<=:(1400C)°燃盡室風(fēng)盡室、度測(cè)十老220%)W2豐噴水點(diǎn)灰取樣“∴∵”「科,…t灰取樣下溫度測(cè)點(diǎn)豐,二Q‰。,‰十22/f%…”Q口2000-匪%:f%<2-..-%-本:‰"°4~12dfI阝。煤漿煤粉1150125013501450T/Cv煤粉T=1200煤漿T=1170豐只W0.51.01.52.02.53.03.52.2.T,.71000C)》…,‰,…,∈aO‰A2.4-f‰<「豐一二》…-%。5》%8酊.2f%2-2士m~0.3pm3,900C,‰6。乙足-g”<3-”十s正≤-千一元中豐乙i「-B-:T,,fs-f正。3--F‰Ⅶ-÷"年,而一f‰s.,辶十》,,‰∈÷”T)f5%~7%30%,E,f%,一§”十中->f”÷,f‰<5”2f‰Tfi-sz->3士<?十∴FAM￡‰軒,a/S=1.5“,「-1200C°二.fl2f‰·>%十%0B‰…(48%);Ca/S=3“WT172C,%>-%‰8E58.94m,2‰-》-‰G￡“4.200C‰一十>,“m,W2.25.09m。E>,“-x“f鈣”>∑,>fx‰之—∑十利”,≥、%‰己∑干》”≤≥▲煤漿Ca/S=1.5∑」>刮∑一%￡「石●煤漿Ca/S=3△煤粉Ca/=2》2-。「”,,f‰←》-E‰∑-…%‰之∑T/℃軒,-2CaCO3￡‰‰。,,魯f可‰2.3Ca/S-,「…-E“,-2,O2”,士s∈a/S豐,Ca/S,壓SO2eaO‰-￥一￡樂7-.10),十ee用Em豐:,f%‰》辶一‰f‰§6f‰》-00010f2-》.000-Wf‰3‰阝+乙。(1)3sf十,辶十L十0。+‰T→0.+,平[1 Falkenberry, SO, Removal by Limestone Injection [J].
