GE Water & Process Technologies Korea “H” Paper Petrocoke Boiler Furnace Slagging Comparison (CEC2571 TEST RESULT) GE Water & Process Technologies Korea

Test Summary Fuel Type: Petro coke Test Period - Before CEC2571: 30 days - After CEC2571: 2011. 07.15~08. 09(25 days) TEST Result - Before using CEC2571 (actually treated by other vendor’s MgO product), the slagging and fouling material nearly blocked the gas passages of tubes. Also, the slagging was so hard to remove during shutdowns. - After using CEC2571, the slagging and fouling was significantly reduced. Also, the slagging was soft and easy to remove during a shutdown. - The boiler system is operating for more than 10 months without plant shutdown.
