PURPOSE: A boiler funnel is provided to improve the outer appearance of the boiler funnel and to prevent the back-flow by connecting a back-flow preventing pipe to a T-shaped pipe. CONSTITUTION: A boiler funnel includes a T-shaped pipe(12) connected to an exhaust gas discharging section. A back-flow preventing pipe(14) is installed at both ends of the T-shaped pipe(12) such that an H-shaped structure is achieved. An exhaust gas discharging hat(16) is formed at upper and lower portions of the back-flow preventing pipe(14) in order to guide the discharge of the exhaust gas. A light emitting diode(22) connected to a power source(20) is installed in the exhaust gas discharging hat(16) so that the exhaust gas discharging hat(16) has an illumination function. A grill is formed at an outlet of the exhaust gas discharging hat(16).
