chemical reaction for a coal boiler scrubber


Boiler Wet Scrubbers - Steel Boiler Wet Scrubber

Boiler Wet scrubber is a form of pollution control technology.. It includes removal from the suction of air stream which includes the harmful gases and dust particles by blower, the gaseous particles are removed by either chemical reaction or absorption of water. Our wet scrubber literally washes dust and smoke particles out of air.
