METHOD (VERSIONS) AND SYSTEM OF AIR POLLUTION REDUCTION Russian patent published in 2013 - IPC F23J15/02 B01D53/00 

FIELD: power engineering.

SUBSTANCE: method to reduce pollution created with a combustion source includes the following operations: contact of a fluid flow leaking out of a combustion source and containing sulphur oxides, with a solid material, formed as a result of mixing of a sludge component, having one or several chemically active silicate compounds, with a binding component, besides, before contacting, the fluid flow has temperature of approximately less than 600°F (316°C), at the same time sulphur oxides available in the fluid flow are removed after contact to provide for efficiency of removal that is more than or equal to 70%, compared to the initial quantity of sulphur oxides, available in the fluid flow before contact. Also a system is described for reduction of pollution extent, as well as a method of pollution extent reduction.

EFFECT: reduced extent of air pollution.
