Zusammenfassung:The utility model discloses a combustion engine backpressure protection device, including reducing flue and booster fan. The flue gas entry of flue gas condensation heat exchanger and the chimney of being connected with exhaust -heat boiler are connected to the reducing flue. In the reducing flue was located to the booster fan, the diameter of reducing flue changed to booster fan direction convergent from the chimney. So, owing to adopted the reducing flue of convergent structure to the influence of flue gas drag increment is overcome to the pressure of the flue gas entrance through booster fan increase flue gas condensation heat exchanger, forms more stable flue gas flow field.
