Abstract

PURPOSE: To easily remove sulfate from a heating surface, by adding specific agents to combusion gas.
CONSTITUTION: Power of at least one of basic calcium compound, magnesium compound, sodium compound, manganese compound and iron compound is mixed or carried with fire-resisting inorganic powder and then added together with ammonia through between an economizer and the are preheater into the combustion gas which has a temperature of 700°C or more and is produced in a combustion chamber of a heavy oil combustion boiler equipped with the air preheater behind the economizer. Thereby, the nitorgen oxides of the combustion gas are reduced and sulfate adhering to the heating surface of the air preheater is easily removed by the combination of the chemical action of the basic substance with the physical action of the fire-resisting inorganic substance.
