Abstract

A method in a furnace (2), which comprises two or several successive spaces (5, 2, 23) with different pressures and at least one passage (11, 21, 30) between them. In the method ash is conveyed by means of a conveyor (34) to said passage and the ash is compressed to the passage by means of said conveyor, wherein the compressed ash prevents the flow of gases between the spaces through said passage. The furnace (2) comprises: a fire chamber; a grate (3); at least two successive spaces (2, 5, 23, 29) with different pressures, comprising at least a first space and a second space; at least one conveyor (34) arranged to move ash from the first space to the second space; and at least one passage (11, 30) through which dry ash can be pushed by said conveyor from the first space to the second space. The ash conveyed by the conveyor plugs and seals said passage.
