Japan-headed Kawasaki Heavy Industries, Ltd has disclosed that it has received an order for an Internal Circulation Fluidized Bed Boiler (ICFB) from GS Engineering & Construction Co., Ltd., world-class engineering, procurement, and construction (EPC) contractor based in Seoul, South Korea. The boiler will be installed at a new waste-to-energy (WtE) facility to be built and scheduled to become operational by Daejeon Metropolitan City, South Korea, in 2017.
According to a statement, the boiler, the value of which has not been disclosed, will be installed at a new waste-to-energy (WtE) facility to be built. The plant will use Refuse Derived Fuel (RDF) as fuel for power generation and heat supply, the latter of which will generate about 50 tonnes of high-temperature, high-pressure steam per hour. The plant is scheduled to become operational by Daejeon Metropolitan City, South Korea, in 2017.
Kawasaki says that its ICFB can burn solid fuel made from refuse and waste plastic, including corrosive materials and environmental pollutants, as well as various waste materials and sludge. The boiler features combustion and heat recovering cells that are divided into separate partitions.
This internal structure allows the fuel and bed materials to circulate from the combustion cell to the heat recovering cells by varying the velocity of airflow. This design contributes to controlling temperature of the fluidized bed and protects the heat exchanger tubes from corrosion caused by chlorine and other gases, thus enabling highly efficient and reliable plant operation.
Third consecutive order
Kawasaki highlight that this is the third and consecutive order in South Korea following the Jeonju Paper Project received in December 2014 and has been awarded based on the recognition of Kawasaki’s proven track record, high performance for contract fulfillment and the superior technology of the two ICFBs delivered in Japan, and one delivered abroad.
The South Korean government has implemented the Renewables Portfolio Standard (RPS) in 2012 with the aim of promoting the development and use of new renewable energies, including biomass and waste materials. Under the system, power suppliers that sell electricity beyond a certain amount are mandated to supply new renewable energies corresponding to a fixed percentage of the total electricity they generate.
Thus the demand for boilers with a highly efficient and reliable operation that can burn biomass and waste materials is expected to grow in South Korea.
