| 摘要 |
The invention relates to a heating plant (1). The plant comprises a combustion chamber (2) for combustion of a solid fuel (F), an outlet (3) from the combustion chamber (2), and a heat exchanger (5) containing a cooling medium and arranged in connection with the combustion chamber. A flue duct (6) is connected to the outlet (3) of the combustion chamber (2) and passes through the heat exchanged (5). Downstream the heat exchanger (5), a cyclone (7) is arranged to separate ash from the flue gases, and a flue fan (8) is arranged to draw flue gases through the flue duct (6). The flue duct (6) and the flue fan (8) are dimensioned to maintain a high velocity of flow in the flue duct (6), all the way from the outlet (3) of the combustion chamber (2) and up to the cyclone (7), in order to achieve a blasting effect on the inside of the flue duct by ash particles being drawn through the flue duct (6). |
