ET-98-22Publication details: Bangkok : Asian Institute of Technology, 1998Description: 105 leavesSubject(s): Online resources: Dissertation note: Thesis (M.Eng.) - Asian Institute of Technology, 1998 Summary: The steel production and energy consumption levels in the recent past and at present, of the two Myanmar Steel Plants: Ywa Ma Steel Plant and Pyin Oo Lwin Steel have been presented. The conditions of Ywa Ma Steel Plant have only been analyzed in detail, as the data of Pyin Oo Lwin Steel Plant has been limited only to the past records. Both of the steel plants in Myanmar are based on secondary steel production route with 15-ton electric arc furnaces (EAF). For Ywa Ma Steel Plant, the specific electricity consumption in electric arc furnace and continuous casting machine are 665 kWh per ton and 40 kWh per ton respectively based on molten steel produced in the year 1997. The first law energy efficiencies of the electric arc furnace, and the largest reheating furnace in Ywa Ma Steel Plant are: 58.3% and 30.9% respectively. The potential energy saving in terms of electricity consumption at main sections in the Ywa Ma Steel Plant with respect to the current best practice values in Iron and steel industry: EAF/CCM, wire processing, and medium and light rolling process are about 286 kWh (1.03 GJ) /ton of molten steel (85.2 % of total electricity consumption), 17.5 kWh (0.06 GJ) I ton of crude steel (5.2 %of total electricity conswnption) and 32 kWh (0.12 GJ) /ton of crude steel (9.6 % of total electricity conswnption) respectively. Analysis of trends of energy consumption based on the decomposition techniques has been used to see the influence of the structure and efficiency changes. The energy demand has been projected to the future: 1998 to 2010 years based on the results of the decomposition analysis. The environmental aspect of steel making at Ywa Ma Steel Plant has been reported. The potential pollutant reduction has been presented comparing current pollutant levels in the Ywa Ma Steel Plant with the best practice values of pollutant levels in USA.

The steel production and energy consumption levels in the recent past and at present, of the two Myanmar Steel Plants: Ywa Ma Steel Plant and Pyin Oo Lwin Steel have been presented.
