Dry desulfurization equipment

Dry desulfurization technology applications 1 Introduction plants in service in our country, a considerable part of the desulphurization facilities not yet complete, according to environmental standards, these plants should be gradually complete desulfurization facilities. But the early construction of desulfurization units generally do not set aside space, after the furnace chimney distance between the very short, narrow space, desulfurization equipment layout difficulties, together with the current power supply, a longer construction period desulfurization equipment, if the machine Leader time to stop construction of desulphurization equipment current tight electricity supply will lead to greater difficulties. Fujian-net with the introduction of the German LLAG company CFB (CFB-FGD) dry FGD technology successfully solved several major problems desulphurization transformation of the old units encountered. Here we Matou Power Plant 6 # furnace, for example, 1 × 200MW unit introduced the original water film dust removal, the transformation of CFB-FGD dry desulfurization and dust removal device, in order to meet environmental discharge requirements. 2 Project Overview Matou Power Plant is located in Handan City, Hebei Province, 15 kilometers south of horse town, southwest of the North China Plain, Taihang Mountain, from the Beijing-Guangzhou railway line, the horse train station about 1 km. 6 unit capacity of 200 MW, with 670t / h boiler. 6 units in November 1979 and put into production, Department of the former Soviet Union boiler tower dry Locke "Red boiler's" factory production ТЛЕ-211С series ЕЛ670 / 140 type. Continuous water boiler slag, after backpass with four sets of Venturi Water filter, using hydraulic ash mode, with a suction blower each two. The desulfurization unit renovation project, is one of the book claim responsibility must be put into operation this year, the project "five" sulfur dioxide emission reduction projects at the national power grid company and the State Environmental Protection Administration signed original proposal limestone - gypsum wet FGD technology , but the presence of high investment funds is limited, site layout difficult issues, difficult to implement, Ma Tau power plant after careful investigation, careful study, that circulating fluidized bed dry flue gas desulfurization process development to mature, taking into account the desulphurization Investment, site layout and construction period and other factors, the final choice circulating fluidized bed dry desulphurization technology as the 6th unit transformation processes.
