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