Nippon Coke & Engineering Orders Kawasaki Steam Turbine Generator
May. 12, 2009
Tokyo, May 12, 2009 — Kawasaki Heavy Industries, Ltd. announced today that it has received an order for a 16.5 MW steam turbine generator from Nippon Coke & Engineering Co., Ltd. (NCE, formerly Mitsui Mining Co., Ltd.). The steam turbine generator will be delivered to NCE’s Kitakyushu Coking Works in Fukuoka Prefecture in April 2011.
The steam turbine generator will be installed in a coke dry quencher (CDQ*). The CDQ quenches red-hot coke, which has been dried by distillation in a coke oven, with inert gas and recovers sensible heat using a boiler to generate steam for power generation. Kitakyushu Coking Works, Japan’s leading coke producer, currently has one CDQ in operation. It plans to accelerate its efforts to save energy and reduce CO2 emissions with the implementation of an additional CDQ through a subsidy from Japan’s New Energy and Industrial Technology Development Organization (NEDO).
Since the launch of its first industrial steam turbine in 1956, Kawasaki has built up a proven track record that includes the delivery of more than 330 steam turbine units. Kawasaki has supplied a number of products to NCE in the past, including a coal moisture control plant. This latest order is a testament to the superior performance and lifecycle cost of Kawasaki steam turbines as well as Kawasaki’s outstanding reliability and proven track record.
*A CDQ quenches red-hot coke, which has been dried by distillation in a coke oven, with inert gases circulating in a quenching chamber. The CDQ quenching process occurs in a completely air-tight environment. The thermal energy, which would otherwise dissipate into the ambient environment as vapor with conventional wet quenching methods, can be recovered by the CDQ and used to generate electric power.
