Order for Steam Turbine Generators Received from Taiwan
Jun. 20, 2011
Tokyo, June 20, 2011 — Kawasaki Heavy Industries, Ltd. announced today that it has received an order for two steam turbine generator (STG) units from Nippon Steel Engineering Co., Ltd. The STGs will be used by Dragon Steel Corporation, a leading steel manufacturer in Taiwan.
These steam turbine generators are designed to be installed in a coke dry quencher (CDQ*1). A CDQ quenches red-hot coke, dried by distillation in a coke oven*2, with inert gas and recovers sensible heat*3 using a boiler to produce steam for power generation.
Dragon Steel, a key subsidiary of China Steel Corporation (Taiwan's largest steel maker), produces coke for use in its steel manufacturing process. The company currently has two blast furnaces, one in operation and another under construction, and is planning to erect two new CDQs with an eye to saving energy and cutting CO2 emissions.
Since the launch of its first industrial steam turbine in 1956, Kawasaki has supplied approximately 340 steam turbine units worldwide, including 13 CDQ steam turbines. This latest order is a testament to the superior performance and lifecycle cost of Kawasaki steam turbines. Its proven track record has made Kawasaki a trusted name across the globe.
Kawasaki continues to expand the sales of its highly efficient power generation systems, boasting a smaller environmental footprint than ever, as it moves forward to bring its energy and environmental business to new heights.

*1 Coke dry quencher |
|
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.

*2 Dry distillation of coal |
|
A process in which coal is heated at high temperatures to be decomposed into coke and volatile gases
|
|
*3 Sensible heat |
|
Thermal energy transferred to or from a substance, resulting in a change of temperature but no change in the substance’s physical state |
