Reject to Power – A Key Technology for Waste Recovery
Incinerating Technology using Spinning Wheels
Whereas classic waste incineration plants incinerate waste on a grate at extremely high temperatures, the incineration process in the Reject-to-Power process takes place at much lower temperatures.
As part of this process, household refuse, industrial waste products from paper, pulp and wood processing plants, or even sewerage sludge are thrown into the furnace by a spinning wheel, spreading the waste products evenly across a grate with different zones. Some waste is also burnt mid-flight. You can find a detailed description of this technique by clicking here.
Efficient Incineration and Optimum Use of Energy
The heat that is generated by this incineration is used to produce steam. The characteristics of the steam can be adapted to suit the relevant requirements – be it for processing heat or for producing electricity. Thanks to the efficient incineration of waste materials and this re-employment of energy, the Reject-to-Power process results in savings on both disposal and energy costs. Christof Industries plants employing this technique can produce between 5 and 30 MWth of heat.
