G4-68型锅炉离心通风机
一、用途GY4-68型锅炉离心通、引风机是适用于火力发电厂中230T/h以下蒸气锅炉的通、引风机系列。在无其他特殊要求时,G4-68型亦可用于矿井通风及一般通风。通风机输送的介质为空气,最高温度不得超过80℃;引风机输送的介质为烟气,最高温度不得超过250℃。在引风机前,须加装除尘效率不低于85%的除尘装置,降低进入风机中的烟气含尘量,以提高风机的使用寿命。二、GY4-68型锅炉离心通引风机性能参数表性能表中提供的参数。通风机性能按气体温度为20℃,大气压力为101325Pa,气体密度为1.2kg/m3的空气介质计算;引风机性能按气体温度为200℃,大气压力为101325Pa,气体密度为0.745kg/m3的烟气介质计算。G4-68型锅炉离心通风机性能参数表产品型号转速r/min序号全压Pa流量m3/h电动机型号功率kWG4-68№8D145012178~148116985~30134Y180M-418.5G4-68№9D145012757~187424183~42906Y200L-43096011207~82416011~28407Y160L-611G4-68№10D145013404~231533173~58856Y250M-45596011491~101021963~38966Y180L-6157301863~58916701~29631Y160L-87.5G4-68№11.2D145014277~290446606~82688Y280M-49096011874~127530856~54745Y225M-63073011079~73623464~41629Y180L-811G4-68№12.5D145015327~362064791~114952Y315L1-416096012335~158942896~76106Y280S-64573011354~91232619~57872Y225M-822G4-68№14D145016681~632791027~114518Y355M2-425026023~4532126263~161499Y355L2-431596012923~277660266~75819Y315S-67522639~199183595~106924Y315M1-69073011697~114845827~81307Y280S-837G4-68№16D96013826~260089960~159606Y355M1-616073012207~150168407~121367Y315M1-87558011393~95254351~96429Y315S-1045Y4-68型锅炉离心引风机性能参数表产品型号转速r/min序号全压Pa流量m3/h电动机型号功率kWY4-68№8D145011540~105915889~29038Y160L-415Y4-68№9D145011952~184422623~28864Y180L-42221756~134431984~41345Y200L-4309601853~58914978~27374Y160M-67.5Y4-68№10D145012413~165831033~56715Y225M-44596011059~72620546~37549Y180L-6157301608~42215623~28553Y160M2-85.5Y4-68№11.2D145013021~208043599~79681Y250S-47596011324~91228866~52754Y200L2-6227301765~53021950~40115Y180L-811Y4-68№12.5D145013767~356160611~77331Y315S-411023394~259085692~110772Y315M-413296011648~113840129~73339Y250M-6377301952~65730515~55768Y225S-818.5Y4-68№14D145014728~324785154~155627Y355M2-425096012070~142256378~103036Y315S-67573011197~82442871~78350Y250M-830Y4-68№16D96012708~256084156~107372Y315L1-611022433~1854118979~153803Y315L2-613273011560~107963994~116954Y315S-8555801991~67750844~92922Y315S-1045)
