The main difference is that in an incinerator the combustion creates an exhaust stream at high temperature. The heat recovery process produces an energy stream that can generate electricity. There are some pollutants that are removed by scrubbers but essentially all of the other combustion products are exhausted to the atmosphere.
Not exactly correct.

I am not sure what you are referring to when you say "not exactly correct". I addressed the products of combustion since
Orange Blossom Baby stated that they were captured/reduced in the power generation equipment. This is not correct. The heat recovery only removes heat and turns it into steam which in turn powers a steam turbine to generate electric power. All of the combustion gases are then exhausted to the atmosphere at a lower temperature.
If you are referring to the removed non combusted solids, I did not refer to that. The non combusted materials, bottom ash, etc. from the incinerator are further processed in a separate group of equipment and some are recycled but nothing is removed in the power generation equipment other than some minor amounts of solids in the incinerator scrubber.
If I did not hit your point please tell me what was not correct. TIA
