The invention relates to an additive with a combustion-promoting and soot-inhibiting effect on heating oils, diesel fuels and other liquid fuels, in particular with a boiling end at normal pressure of over 300 ° C. In order to keep the efficiency of incineration plants high, they are operated with as little excess air as possible. However, this increases the risk of soot formation, which pollutes the environment and reduces the heat yield of the incineration plant. Conventional combustion-promoting additives have the disadvantage that they adversely affect the storage stability of the fuels. These disadvantages are inventively prevented or at least reduced by admixing the liquid fuel with an additive which is characterized in that it contains one or more oil-soluble and / or dispersible compounds of transition metals and / or alkaline earths and one or more inhibitors against Polymerization and oxidation of hydrocarbons, these inhibitors being heat-stable and, due to their vapor pressure and / or their decomposition temperature, temperatures of 300 ° C. and above at normal pressure can be exposed at least without loss of their polymerization-inhibiting effect. |
