Furnace flue-gas purification - by water scrubbing for domestic or ind applications

Combustion fumes from furnace are purified by first compressing by about 50%, secondly mixing with water to collect soot and ash and absorb oxide fumes (esp. sulphur based), thirdly expanding to atmos. pressure which cools fumes and coagulates water spray. Pref. centrifugal compressor, water-pump, and venting turbine are coaxial driven by single electric motor under furnace temp. control. Sulphur oxides may be neutralized by lime introduced into scrubbing water, which may be recirculated after cooling in heat exchanger with second water stream providing supplementary heat source. Sulphite in scrubbing water may be oxidised to sulphate by primary air to burner which will then be preheated and saturated with water to reduce sooting.
