Wood boiler with integral combustion chamber with flue flue inverted and flat tube for natural convection

摘要

PURPOSE: A timber boiler with an integral combustion chamber with a disposed upside down flue and a flat tube for natural convection is provided to use the calorie of timer to the maximum by enhancing heat transfer effect according to the temperature distribution of flame and the exhaust characteristic of combustion gas. CONSTITUTION: A timber boiler(100) comprises a steel combustion chamber(10), a water tank(20), and an exhaust pipe(27). Timber is put into in the steel combustion chamber. The water tank surrounds the combustion chamber. The exhaust pipe is arranged at the upper end of the combustion chamber. A copper heat transferring flat tube(13) is tranversely arranged inside the combustion chamber. The hole enabling the water of the water tank to flow is pierced at the flat tube. The flat tube is formed as a flat tube shape. A copper heat transfer plate(12) is arranged at each of one or more sides of the combustion chamber.
