Abstract: A method for simultaneous removal of NO and carbonic particles and inorganic dust from flue gases in a reactor with a catalyst for direct decomposition of nitric oxide located on a metallic monolith, includes tangential introduction of flue gases to the reactor circumference. Flue gases flow rotationally and downwards in the reactor in contact with an undulating surface of metallic foil located on an inner wall of the reactor chamber and in contact with the catalyst on a spiral band falling to the lower part of the reactor, and next flue gases jet direction counter-currently to a cylindrical inner chamber containing slices of the monolithic catalyst disturbing laminar flow of the flue gases jet. The reactor arrangement provides for simultaneous removal of NO and carbon particles and inorganic dust from flue gases.

Abstract: The method of simultaneous removal of NO and carbonic particles and inorganic dust from flue gases in the reactor equipped with the catalyst for direct decomposition of nitric oxide located on a metallic monolith consists in tangential introduction of flue gases to the reactor circumfer-ence generating rotational flow of the flue gases downwards of the reactor with simultaneous flow disturbance due to flue gases contact with undulating surface of metallic foil located on an inner wall of the reactor chamber and split of the flue gases by contact with the catalyst located on a spiral band falling to the lower part of the reactor, and next flue gases jet direction counter-currently to a cylindrical inner chamber containing the slices of the monolithic catalyst disturbing laminar flow of the flue gases jet. The deposited solid particles of the pollutants are collected in the lower part of the re-actor.

Abstract: An amorphous alloy which is resistant to hot corrosion in sulfidizing and oxidizing atmospheres at high temperatures, consisting of at least one element selected from the group of Al and Cr and at least one element selected from the refractory metals Mo, W, Nb, and Ta, a portion of the set forth refractory metals being allowed to be substituted with at least one element selected from Fe, Co, Ni and Cu. The addition of Si further improves the alloy's oxidation resistance.
