Report of year 2000 version on basic study for promotion of joint implementation. Feasibility study on energy saving at Anshan Iron and Steel Group Complex

Abstract

In order to promote the COP3 joint implementation, a survey was conducted in fiscal 1999 at Anshan Iron and Steel Group Complex in China. The complex is the leading iron and steel maker in China. The unit requirement for energy consumption per ton of crude ore is 7.00 Gcal, which is close to 1.4 times that in Japan. The feasibility study has discussed and planned modification of ignition furnace facilities and waste heat recovery in the sintering process, top-pressure gas recovery at uniform pressure, and top-pressure recovery turbine (TRT) in the blast furnace, based on the locally available data and surveys. The modification of the ignition furnace in the sintering process resulted in reduction of fuel consumption of 578.0 TJ/year in the facility No. 2, and 718.9 TJ/year in the facility No. 3. The amount of electric power generated by the TRT is 121.13 GWh/year assuming the annual blast furnace operation factor of 90%. This can be converted to the heat quantity of 1,370 TJ/year. The top-pressure gas recovery amount is 163 TJ/year when converted to the heat quantity. Annual CO2 reduction amounted to 15,373 tons. The profitability was discussed by using the present worth method. Because of coal price  More>>

The profitability was discussed by using the present worth method. Because of coal price being low and the energy unit price being low in China, it was revealed that the profitability at the private sector level could not be achieved. (NEDO)}
