Environment-friendly firing for coal fuels preferably for steam boilers

摘要

To prevent high temperatures in industrial furnaces, at which harmful substances, especially thermal nitrogen oxides, which can be released into the atmosphere with the flue gases, are formed the conversion of the chemically bound pollutants in the fuel into sensible heat is carried out in two or more coupled processes for combustion and gasification, the temperature being kept below predetermined limits and the fuel heat being liberated in stages.
