Order Received for Municipal Waste Incineration Plant in Osaka
NKK has received a ¥28.5-billion order from the Osaka City Environmental Project Bureau to design and build a municipal waste incineration plant and related facilities for the city's Hirano Clean Center in Hirano ward. This is NKK's first order from Osaka although the company has previously supplied several waste disposal plants in the Kyoto-Osaka-Kobe area, including Kyoto's 600-ton-per-day South Municipal No.l Plant. The Hirano waste incineration plant, with a daily treatment capacity of 900 tons, will be a refurbished version of an existing plant (600 tons/day), which was completed in 1971. The plant will incorporate NKK's latest technology for incineration, limiting the generation/emission of dioxins and other pollutants, and utilizing waste heat generated during incineration for power generation with maximum efficiency. Scheduled for completion in April 2003, it will be one of the largest waste disposal plants in Japan. The plant will be equipped with two 450 ton-per-day stoker incinerators employing NKK's two-way hyper-grate furnaces, which ensure highly efficient, uniform combustion. In terms of exhaust gas control, dioxin emissions will be reduced to less than 0.1 ng-TEQ/Nm3 , hydrogen chloride below 15 ppm, and nitrogen oxides below 20 ppm. The plant will also comprise high-temperature, high-pressure boilers designed to recover waste heat from the incinerators to generate a maximum 27,400kW of electricity. Civil engineering and building-related works will be undertaken by a joint venture formed by Kumagai Gumi Co. and three other construction companies. This Osaka City waste incineration plant is the largest order placed by a domestic municipality in fiscal 1998. Helped by this order, NKK's municipal waste incineration plant orders in the fiscal year increased considerably from the previous year in contract value, despite a current market depression reflecting tight municipal finance and environmental concerns expressed by local residents. |
