Additives recovery from incinerator exhausts - using cooling stage after electrostatic precipitator to condense out and recycle additives

摘要

Additives are recovered from the gas cleaning on the exhaust from waste incinerators by introducing a cooling stage after the filter which is normally an electrostatic precipitator. Additive recovered together with some quantities of wash liquor are reintroducing before the electro-filter. The process is used as part of the gas cleaning system on waste incinerators. The cleaning process uses additives described in DT 2538312. This process recovers these additives, thus reducing the operating cost.
