Yeong-heung

Bituminous coal

• Location: Yeongheung Island, about 40km from Seoul
• Resource used to generate electricity: Bituminous coal
• Imports Bituminous from (not in Korea): 
• Austrailia (37%), China (4%), Indonesia (35.5%), Canada (9.3%) 
• Russia (7.5%), U.S. (2.5%), etc (4.2%)

Bituminous coal

• Primary consistuents are maceral (coal component):
• (vitrinite & liptinite)
• carbon content: 60-80%
• rest composed of: 
• water, air, hydrogen, sulphur

Resource used

• 150,000 ton & 200,000 ton ships
• coal yard -- 600,000 tons
• Unit 1 & 2 = 2,415 ton/h  x  2
• Unit 3 & 4 = 2,637 ton/h  x  2

Electricity generated

• 20% of electricity of metropolitan seoul
• Unit 1 & 2 = 800MW  x  2
• Unit 3 & 4 = 870MW  x  2
• Photovoltaic power plant = 1,400 MWh
• hydro power plant = 11,892 MWh

Environmental Effect

• generates 1.1million tons of coal cinders
• -- material produced from incomplete combustion of coal
• 37% of coal cinders recycled
• expected to raise to 95% of recycling rate
• lifespan of landfills will be expanded to 70 years
