    Waste incineration and biomass combustion produce a complex and hard to control combustion process, which also causes detrimental conditions to boiler materials.Boiler tubing, such as superheaters, can experience severe material wastage due to corrosion and erosion.In this study, a novel approach to both monitor the temperature of a boiler and protect the susceptible boiler construction is introduced.The main innovation is to combine a protective coating and temperature monitoring optical fiber by developing a novel temperature monitoring protective coating.Protective HVOF and arc sprayed coatings have been tested in high temperature corrosion laboratory tests and in real boiler conditions.Analysis of the samples has been performed with SEM/EDS.In this paper, the preliminary results of developing the monitoring coating system are introduced.
