Energy recovery during incineration

Energy recovery system is necessarily integrated with incinerator to utilize the generated heat energy. The overall efficiency of the incinerator is depended on the utilization of the recovered energy. The heat energy generated in the furnace can used for district heating as well as electricity generation. District heating has less revenue but higher efficiency, while lower efficiency shows on electricity generation.

The flue gases generated in the furnace have a high temperature of 1,000^oC-1200^oC. This temperature should be lower down before the gases passed on to the cleaning system. The cooling process shall be implement with a boiler, and the heat energy inside the gases can be transferred into water and become steam.  Then, the energy can be recovered to provide district heating and high-pressure steam can be pumped into turbine to generated electricity. It should be noticed that the feasibility of steam store is low, which means consumers should be contracted to the manager before the incineration project. As to the production of electricity, it is possible to generate it directly by incinerate prepared waste in pressurized fluidized bed.

Meanwhile, Water that may be used to cool down the furnace during the incineration should be recycled. Energy recovered from the water can be utilized for in-plant used straightforward. Moreover, the steam generated is possible for backup electric-driven equipment as well.
