    • In a method of removing dioxins in a waste incineration plant for cooling combustion gases from an incinerator by means of a first and/or second heat exchangers, and for exhausting the gases into the atmosphere through a dust collector of a bag-filter. The method comprises the steps of controlling a temperature of the gases right after the first heat exchanger within a range of 200.degree. C..about.140.degree. C., by use of the first heat exchanger, and also controlling a pressure loss of the gases right after the first heat exchanger within a range of -20 mmH.sub.2 O.about.-60 mmH.sub.2 O.
    • 在通过第一和/或第二热交换器从焚烧炉中除去废气焚化装置中的二恶英并且通过袋式过滤器的集尘器将气体排出到大气中的方法中, 该方法包括以下步骤:将第一热交换器之后的气体的温度控制在200℃的差异140℃,通过使用第一热交换器,并且还控制气体的压力损失 第一换热器在-20mmH2O差异-60mmH2O的范围内。
