ABSTRACT:
The invention relates to a method and apparatus for feeding reaction substances, i.e. pulverous solid material and reaction gas, into a smelting furnace, particularly into the top part of the reaction space (1) of a smelting furnace. The reaction gas is fed into the reaction space (1) through at least one feed gate (9) so that the solid material supplied through this feed gate (9) are fed into the reaction space (1) from an area in between the two sub-flows (5, 6) of the divided reaction gas supply flow. Roughly 50-90% of the reaction gas supply is fed from outside the solid material supply.
