    摘要: The invention is directed to a process and to an apparatus for saving fuel in furnaces for thermal dissociation of halogenated aliphatic hydrocarbons, especially of 1,2-dichloroethane, using chemical dissociation promoters or physical measures which initiate the dissociation reaction.The initiation of the dissociation reaction lowers the temperature level in the reaction mixture with the same conversion. This can also lower the mean firing chamber temperature and save fuel.In a preferred process variant, flue gas leaving the convection zone of the dissociation oven is analyzed and its dew point is calculated. The dew point of the flue gas or the conversion of the dissociation reaction serves as command parameter for the intensity of the physical measure for initiation and/or for the amount of the chemical dissociation promoter added and/or for the amount of fuel.In a further preferred process variant, the latent heat content of the flue gas is used to preheat the burner air or other media.
