PURPOSE: A blowing module for a boiler is provided to extinguish a burner unit before the burn-down of fuel by selectively cutting off the inflow of air into the burner unit. CONSTITUTION: A blowing module(400) for a boiler comprises a blowing unit(420), a shutter, a shutter housing(440), and a rotating unit(460). The blowing unit connects to the burner unit and supplies external air to the burner unit. The shutter is rotatably mounted on an inlet of air flowing into a blowing unit. The shutter housing accepts the shutter and surrounds an inlet. The rotating unit is installed on one side of the shutter housing. The rotating unit is coupled with the shutter to transfer torque. |
