The most severe corrosion problems in biomass-ﬁred systems are expected to occur due to Cl-rich deposits formed on superheater tubes. The presence of alkali chloride salts in deposits may cause accelerated corrosion well below the melting point of the salt.
Unrefined biomass contains high levels of potassium and other alkalis, which cause deposit formation and corrosion in the boilers of combustion …

Corrosion behaviour of steel used in boilers for biomass combustion Katarzyna Irena Siwek Thesis to obtain the Master of Science Degree in Energy Engineering and Management Supervisor: Prof. Maria de Fátima Grilo da Costa Montemor Examination Committee
However, high-chlorine fuels (Clar>0,2%) like: biomass, waste and high chlorine coals generate the risk of intensified corrosion process and a limited steel mechanical strength is observed. The paper presents a thermodynamic analysis of chloride-induced corrosion in the Fe-O-Cl system.
In particular, the presence of potassium chloride (KCl) in the deposits is believed to play a major role in the corrosion observed in biomass-fired boilers. The presence of KCl in the deposit can cause selective chlorine corrosion of chromium and iron, leaving a

Lesson 3 also deals with high temperature corrosion in biomass boilers. But this is to be seen as an extension of the study I presented in lesson 2. We will talk about the purpose of the study and the experimental conditions under which this was done. There
2010/12/22 · Prevention of corrosion in coal fired boilers can usually be accomplished by using a higher alloyed steel typically with a higher content of chromium. In biomass fired boilers the corrosion is caused by chlorine, and the chlorine tend to selectively remove the chromium and to a lesser extent the iron out of the steel.
chloride-induced corrosion, although attack by acid/basic fluxing caused by sulfate deposits, molten chlorides, and oil-fired boiler environment (70% V2 O5-20% Na2 SO4 …
Chloride corrosion in biomass-fired boilers – Fe-O-Cl system thermodynamic analysis Robert Kaczmarczyk1,a and Agata Mlonka-Mędrala1 1 AGH University of Science and Technology, Faculty of Energy and Fuels, 30 Mickiewicza St., 30059 Krakow, Poland
biomass-fired systems are expected to occur due to Cl-rich deposits. In general, chlorine gas can influence the corrosion in many ways. Gases containing Cl 2, HCl, and KCl may cause a direct corrosion by increasing the oxidation rate of the metal alloys
