ABSTRACT:
In a process for gasifying and burning waste materials, the waste materials are introduced into an incinerator (1) and end up on a burning grate (6) to which combustion air is conducted through various undergrate forced draft chambers (8a to 8e). In the first area combustion air is introduced at a superstoichiometric level in order to ignite the waste materials. Then, via the undergrate forced draft chambers (8c to 8e), oxygen is mixed into the air which is used for the gasification, thereby establishing a substoichiometric level which results in gasification of the waste materials. The combustible gases which result from this process pass via a waste gas flue (12) into a second furnace (2), in which the gases are burned at a superstoichiometric level through the introduction of combustion air. The resulting waste gases pass to a heat exchanger (3).
