Coal Fired Power Boiler System for Bottom Ash Removal Without Water, 1996 Engineering Conference Proceedings
Recent environmental regulations in Europe have forced power plant operators to close ash ponds and reduce sluice water effluent to a zero discharge, This presentation reviews how a European designed bottom ash removal system was applied to a USA Power Boiler located in Florida, where local regulations on water usage encouraged the retrofit of a zero discharge ash removal system. Design cost and energy comparisons to typical sluice systems are described. Also initial operation, problem identification, correction and present status are included. The system will have operated for three years at the time of this presentation and world- wide systems of a similar design already have over 275,000 hours of actual retrofit operation.
