ABSTRACT:
An apparatus for detecting a head wind in a gas boiler and method is disclosed which is capable of the magnitude of variation of voltage corresponding to the R.P.M. of an exhaust fan and the combustion state of flame. A microcomputer in the gas boiler detects the R.P.M of exhaust fan and voltage applied to the exhaust fan when the R.P.M exceeds a normal limit. The detected voltage is compared with a reference voltage. If the compared result exceeds a predetermined value, to sense the combustion state of flame an infrared rays sensor is used. When the head wind is introduced into an exhaust conduit, the red wavelength is sensed at flame due to incomplete combustion. Accordingly, in case that the magnitude of variation of voltage exceeds a predetermined value and the red wavelength is sensed, microcomputer can detect the head wind.
