handling system. Therefore, the ash can be conveyed by means of a pneumatic conveying system to the final silo (Figure 7). A trial operation showed that mixed fly and bottom ash from a coal fued power plant can be reused as raw material for cement production [6]. By mixing the ash its disposal is simplified as the combined ash is sent to the
There are primarily four systems which are necessary for effectively handling and disposing the ash generated in coal based thermal power plants. These are: 1. Water system 2. Fly ash system 3. Bottom ash system 4. Ash evacuation system From an operation point of view there are three systems. They are: 1. Bottom Ash System 2. Fly Ash System 3.
BOTTOM ASH CONVERSION OPTIONS AND ECONOMICS 6 Conventional Dewatering Systems: When new power plants were being designed in the 1970's, the state of the art ash handling systems at the time were closed loop water recirculation systems that involved a "tank farm" thousands of feet away from the boiler.
