Five Year Performance and New Challenges at a State-of-the-Art Fluidized-Bed Municipal Sewage Sludge Incinerator System

This paper presents actual performance of a fluidized bed incinerator system with unique air emission control technologies at YCUA for five years. Data includes operation, sludge quality, and air emission from the System with historic comparison. This paper also describes improvements in the sludge quality over the years, due mainly to a successful program YCUA developed under the Industrial Pretreatment Program. This paper also presents challenges brought about by new MACT rules U.S. EPA promulgated that took effect in 2011. The plant is improving operational flexibility by demonstrating regulatory compliance without GAC.
