PURPOSE: A boiler using firewood and electricity is provided to keep heat after combustion for a long time and to facilitate the connection of a pipe. CONSTITUTION: A boiler using firewood and electricity comprises a main body(110), a combustion chamber(120), a combustion flue(130), a hot-water supply pipe, a spiral water-heating pipe, an electric heater rod and a ventilation duct(170). The combustion chamber is integrally formed with the main body. The inside of combustion flue is formed into a hollow conduit line. The combustion flue discharges the combustion gas to outside. One end of the hot-water supply pipe is located in the top of inside of the main body and is expanded from the lower part of the main body as outside. The feed water heating pipe is spirally circled the combustion flue surrounding. The electric heater rod produces heat for electric supply. The ventilation duct comprises a ventilation cowl, an exhaust line for ventilation, and a blowing fan(173). |
