ABSTRACT:
This invention relates to a method and device for converting energy by combustion of solid fuel, especially incineration of bio-organic fuels and municipal solid waste to produce heat energy and which operates with very low levels of NOx, CO and fly ash, in which that the oxygen flow in the first and second combustion chambers in at least one separate zone and by sealing off the entire combustion chambers in order to eliminate penetration of false air into the chambers, the temperatures in the first and second combustion chamber are strictly controlled, in addition to the regulation of the oxygen flow, by admixing a regulated amount of recycled flue gas with the fresh air which is being led into each of the chambers in each of the at least one separate zones, and both the recycled flue gas and fresh combustion gases are filtered in unburned solid waste in the first combustion chamber by sending the unburned solid waste and the gases in a counter-flow before entering the gases into the second combustion chamber.
