| 摘要 |
A method and apparatus for recovering heat from solid material, such as ash, removed from hot processes such as combustion or gasification processes and/or from cleaning processes of hot gases. The ash is conducted from a combustion chamber (2) or from a gas cleaning means (16) into a heat exchanger (8), where it is brought into heat exchange contact with liquid for transferring heat from the ash to the liquid. The liquid heated in this manner is mixed with the feed material of the hot process, such as for example coal, in a mixing chamber (14) for moistening and preheating the feed material prior to feeding thereof into the combustion chamber (2). |
