一、风机的用途
G4-73与Y4-73型锅炉通、引风机适用于火力发电厂中2~670T/h蒸气锅炉的通、引风机系统。在无其他特殊要求时,G4-73亦可用于矿井通风及一般通风。
通风机输送的介质为空气,较高温度不得**过80℃;引风机输送的介质为烟气,较高温度不得**过250℃。
在引风机前,必须加装除尘装置,以尽可能减少进入风机中烟气的含尘量。根据一般电厂使用情况,除尘效率不得低于85%。
二、G4-73型、Y4-73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。
