Paul Wurth IHI Co., Ltd.has reached an understanding with a leading international steel group for upgrading their existing dilute phase PCI plants in Japan. The key measure of these modernizations is the installation of Gritzko type coal flow control valves in the injection lines. This installation is based on the excellent operation results reported from a recently commissioned Paul Wurth PCI plant.
A first order for the supply of over 160 Gritzko valves for two blast furnaces has been awarded in March 2017. Orders for the customer’s further blast furnaces will follow gradually until March 2018. All projects will be awarded on EPC basis and the scheduled completion for these projects encompassing around 700 Gritzko valves will be April 2019.
Paul Wurth IHI management believes that this achievement will help to further promote upgrades for existing PCI plants of both dense phase and dilute flow systems.
Pulverised coal injection (PCI) helps to reduce the cost of ironmaking and the carbon footprint of the primary cycle of integrated steelmaking.
