用途
G4-73与Y4-73型锅炉通、引风机适用于火力发电厂中670t/h以下蒸汽锅炉的通、引风机系统。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，必须加装除尘装置，以尽可能减少进入风机中烟气的尘含量。
结构特点
风机主要由叶轮、机壳、进风口、调节门及传动部分组成。
（1）叶轮由后倾机翼斜切的叶片焊接而成，由于采用了机翼形叶片，保证了风机高效率、低噪声、高强度。叶轮经静、动平衡校正，故运转平稳。
（2）机壳是用普通钢板焊接而成的蜗形体。
（3）收敛、流线形的进风口制成整体结构，用螺栓固定在风机入口侧。
（4）调节门是用来调节风机流量的装置，轴向安装在风机前面。
（5）传动部分的主轴由优质钢制成，本风机均采用滚动轴承。轴承箱由整体的筒式轴承箱和枕式轴承箱。
