Incinerator operation
When waste reaches an efw plant, it is received into a pit where an overhead crane mixes it evenly and feeds a charging hopper. The waste handling area is kept under negative air pressure to avoid the escape of dust and odour. The temperature is maintained at 850oC or above, for at least two seconds, which ensures complete combustion of the waste. Energy is recovered from the hot flue gases by a boiler system, creating steam to turn a turbo-generator which feeds the electricity grid.
