German company KSB Aktiengesellschaft has been awarded contracts to supply four new-generation boiler recirculation pumps to two Chinese developers for new state-of-the-art coal-fired power plants. The new power plants will be located in Laiwu of the Shandong province and Taizhou of the Zheijang province.
The new plants are being designed to use twice-heated boiler technology, the only technology of its kind in the world which is capable of handling the highest temperature and pressure requirements for power plant boilers, according to KSB. The German pump manufacturer will supply pumps from its LUVAk series designed to handle pressures of 400 bar and operating temperatures of 425 degrees Celsius. The pumps are driven by high voltage motors with supply voltages of 6,000 and 10,000 volts. The drive rate of the pumps is about 800 kilowatts.
KSB said the development of the new pump sets marks a technical milestone and provides two key reference projects. The pump sets are scheduled for delivery in November 2014 (Laiwu) and February 2015 (Taizhou).
China is pushing the creation of new power plants throughout the country because of its need for a more reliable energy grid. Much of China's coal is in the interior regions of the country leading to difficulties in transporting the resource to areas in need. It also relies on importing foreign coal, particularly from Australia and Indonesia to make up for the shortage of its internal supply.
