Typical SunCoke Energy Battery<br />
• Coal specifications<br />
– Typical volatile matter is 21% to 28%, campaign 19% to 32%<br />
– Average reflectance range of 1.00 to 1.65<br />
• Can generate steam or power<br />
– Approximately 9 MW / 100 kmt annual Run of Oven coke production<br />
– Annual power production of 788 kW-h / mt coke<br />
• No wastewater treatment plant required<br />
• Can be constructed on a new site or exist<strong>in</strong>g site (brownfield)<br />
• 48 hour cycle / 43.2 metric tons (48 short tons) coal<br />
• 1540C max temperature<br />
• Plant designed for 30 year run life<br />
• Approximately 2 – 4% Yield Loss<br />
• 2 – 5 CSR <strong>in</strong>crease over By-product plant us<strong>in</strong>g same coals<br />
– Improved Strength attributed to slower heat<strong>in</strong>g rate, higher temperatures and longer soak<br />
time result<strong>in</strong>g <strong>in</strong> consistent crystal growth<br />
