Description

technical field

[0001] The invention relates to a flue gas desulfurization atomizing ceramic nozzle used for a coal-fired generator set in a thermal power plant, and also provides a manufacturing method for the flue gas desulfurization atomizing ceramic nozzle. Background technique

[0002] Flue gas desulfurization is currently used to control SO in thermal power plants 2 Emission is effective and the most widely used technology, and the atomizing nozzle is a key component in the wet desulfurization device. Chinese patent 02112991.6 discloses a "conical spiral nozzle for desulfurization and dust removal, its manufacturing method and mold". The nozzle is made of ceramic materials. It is precisely formed by grouting once, and the selected ceramic materials can be alumina porcelain, corundum, zirconia, silicon carbide, etc. The content of alumina is 75-99%, and 5-25% of zirconia is added. It is conventional 95 porcelain, and its disadvantages are (1) poor wear resistance. Bec...
