Abstract: A method and apparatus for burning hydrocarbons or other combustible liquids and gases, the apparatus (APP) has been provided with at least one inlet for a liquid and/or gaseous fuel (FUE) and air (AIR) and at least one outlet (EXHG) for gases for removing the gases (EXHG) generated in the apparatus (APP), at least one measurement and adjustment unit (C) for adjusting the amount of fuel (FUE) and air (AIR), at least one pre-combustion zone (Cz11, Cz12, Tz1) for the partial combustion of gases, and at least one post-combustion zone (Tz2, Cz21, Cz22) for the combustion of gases generated in pre-combustion, for the reduction of NOx's produced in pre-combustion, and/or for the oxidation of hydrocarbon and carbon monoxide emissions.
