PURPOSE: A detachable air inflow control apparatus of a firewood boiler, which prevents the malfunction and a deformation of a motor by protecting a precision control motor from fire and humidity, is provided to maintain the uniform fire power by using a precision control motor. CONSTITUTION: A detachable air inflow control apparatus of a firewood boiler comprises an air injection opening/closing device(100), an open and close driving room(40) and a precision control motor. The air injection opening/closing device is composed of an outer tube(10), a rotary shaft(20) and an air control disc(30). The outer tube is installed in the air injection hole of the outer wall side of the combustion chamber of a boiler. The rotary shaft passes through the outer tube in a diametric direction. |
