Abstract

The invention relates to a method for gasifying carbon-containing fuel in a fixed layer gasifier according to the countercurrent principle, where fuel is fed to the gasifying reactor to at least one point, which is, when seen from the reactor bottom up, at a height that is 20-70 % of total height of the reactor, whereby below the feed point the fuel bed forms a primary zone, where pyrolysis, reductive and oxidative reactions occur, and whereby primary air is fed from under the fuel bed and from the reactor, from above of the fuel bed, product gas is removed. The invention is characterized in that to the gasifying reactor (7), to the secondary zone above the feed point of the fuel (1) and above the fuel bed, secondary air is fed at least to the immediate vicinity of the fuel bed. The invention relates also to an apparatus for application of the method.
