Abstract

A combustion process wherein a comburent, a fuel and the following components are fed: i) component B) sulphur or compounds containing sulphur in an amount to have a molar ration B1/C1≧0.5, wherein B1 is the sum by moles between the total amount of sulphur present in component B)+the total amount of sulphur (component B11)) contained in the fuel, C1 is the sum by moles between the total amount of alkaline and/or alkaline-earth metals contained in the fuel (component C11))+the amount (component C)) of alkaline and/or alkaline-earth metals in the form of salts and/or oxides contained in component B), ii) component A), comprising low-melting salts and/or oxides or their mixtures, having a melting temperature<1,450 K, wherein the ratio by weight A′/(A″−A′)≧1:100, wherein A′ is the sum by moles between the metals under the form of low-melting salts and/or oxides or their low melting mixtures in the component A) and the amount of metals of low-melting salts and/or oxides contained in the fuel, A″ is the sum of the amount of all the metals contained in the fuel and those contained in component A), in which the combustor is isothermal and flameless.
