  • Method and plant for producing high steam temperatures when burning problematic fuels
    Patent number: 5619933
    Abstract: When burning problematic fuels, the hot flue gas produced is held physically separate from the superheater (4) of the plant, a part of the hot flue gas being made to flow towards a heat exchanger (3), in which an energy carrier is heated and transfers the heat to the superheater (4). In this manner, problems due to high-temperature corrosion are avoided.
