摘要：
A simple and effective system has been developed to clean the waste gases formed in small furnaces. It is proposed that a 5–10% solution of Ca(OH)2 be used to neutralize SO2 in the gases. The correct amount of solution to use has been determined. Activated charcoal of the 3–20 mm fraction has been tried as the adsorbent and can be used repeatedly after desorption. A high degree of efficiency is obtained in cleaning the waste gases: 88–99% for charges of composition I and 91–98% for charges of composition II.
