<p>PURPOSE:To enhance dust collection effect in an electrostatic precipitator by adding both a specified alkaline earth metallic compd. and an SO3 adsorbent of specified amount therefor to combustion gas contg. SO3 of a boiler and introducing this mixture into the electrostatic precipitator. CONSTITUTION:The mixture of both one or more kinds of alkaline earth metallic compds. selected from magnesium and calcium compds. and an SO3 adsorbent consisting of the rate of 5-50wt.% for this alkaline earth metallic compd. is added to combustion gas contg. SO3 of a boiler. Then this mixture is introduced into an electrostatic precipitator and dust collection of the combustion gas of the boiler is performed. As an embodiment of used magnesium compd. and calcium compd., CaCO3, CaO, MgCO3 and MgO, etc., are used. Further as the SO3 adsorbent, silica, alumina, iron oxide such as Fe2O3, diatomaceous earth, activated carbon, acid clay and bentonite, etc., are used.</p> |
