Growing market share for AUMUND in the Chinese power industry
Despite the declining number of new construction projects in the power sector, the AUMUND Group has secured an increased market share in the Chinese power industry over the past two years. The combined efforts of the AUMUND subsidiary in Beijing and the AUMUND power technology team in Germany has resulted in orders for several power stations belonging to the Shenhua Power Group, as well as from Shanneng and Guodian.
Tightening of environmental protection regulations has led to an increased volume of enquiries for flue gas purification systems from power plant operators in China, who are now opting for silos rather than stockpiles for their gypsum storage. AUMUND has noted increased interest in flue gas desulphurisation and silo discharge with AUMUND Rotating Rotary Discharge Machines type BEW-K. The rotating rotary discharge machine was specially developed for large extraction openings and silos of 6 to 14m diameter. A typical application is the extraction of FDG gypsum in coal-fired power stations. These machines work on the first-in, first-out principle, are designed for mass flow and can feed and extract the material at the same time.
AUMUND received orders from the Shenhua Group for the supply of two rotating rotary discharge machines to each of four power plants, in Luzhai, Jiujiang, Ningdong and Ezhou. The eight machines were installed, over a period of about two years, for the discharge of FDG gypsum from the respective silos into trucks.
Following this success, AUMUND received another order, from the Shanneng Group for its power plant in Zhaoshipan. In this case a rotating rotary discharge machine with a diameter of 10m and a capacity of 150t/h was ordered. China Shenhua Energy Company Limited was incorporated in 2004 in Beijing and is a subsidiary of Shenhua Group Corporation Limited. The company has extensive coal reserves in the People’s Republic and is a leading energy provider. Its main business includes production and sales of coal-derived power and coal-related products, as well as transportation of these products using its own integrated network of railway and shipping routes.
Samson® Material Feeder type 1600 for the power plant in Fengcheng
The sales success of AUMUND Beijing was enhanced by the order to supply a Samson® Material Feeder type 1600 for coal handling in the Guodian power plant in Fengcheng. Mobile conveyors of this type are installed in applications all over the world, predominantly to receive correctives, additives and alternative fuels.
The Samson® has already proved its flexibility in being able to handle such a diverse range of conveying properties displayed by materials like sewage sludge, manufacturing by-products, biomass and industrial or domestic refuse. The machine is now underlining its flexibility in the Asian power industry.
Unlike on conventional tipping yards, the Samson® Feeder does not just deposit the material but actively extracts it from the truck. In this way, a regulated material flow is achieved, irrespective of whether the materials are wet, sticky, heavy or abrasive. Furthermore, the machine is installed above ground, with no need for preparatory construction, and no expensive civil works for deep pits or underground hoppers. Being mobile, it can easily be repositioned for use in different locations and even provides temporary buffer storage capacity. The wide-apron belt design eliminates bridging or spillage, giving a reliable conveying solution whatever the material.
