FIELD: heating.
SUBSTANCE: invention relates to a boiler cleaning method, in which, while in the combustion chamber (C) of the boiler fumes (F) are formed and propagate up to the boiler heat exchangers, into combustion chamber is injected aqueous solution (S) of dissolved chloride and/or magnesium sulphate and/or dissolved calcium chloride in form of droplets, which as a result of evaporation from an aqueous solution of water with subsequent thermal decomposition are converted into a combustion chamber into particles of magnesium oxide and/or calcium, which when mixed react in combustion chamber with molten salts and/or molten oxides presented in fumes, so as to lead to crystallisation of said molten salts and/or to glass transition of said molten oxides before said melted salts and/or said molten oxides come into contact with heat exchangers. Invention also relates to device for implementation of this method and to boiler equipped with such device.
EFFECT: boiler cleaning method, corresponding device and boiler are proposed.
