Coating solutions against high temperature corrosion - performance validation and feasibility at biomass fired boilers
Abstract
To overcome severe corrosion problems of heat exchangersurfaces, especially superheaters, in biomass firedboilers protective thermal spray coatings can be applied.Fouling and corrosion in biomass boilers originate fromused fuels, which contain alkali metals, chlorine andother corrosive elements, and can lead to tube failureand leakage in the worst case. Different HVOF (highvelocity oxy-fuel) and arc sprayed coatings were exposedto biomass co-combustion conditions in a CFB boiler usingpeat, coal, SRF and biomass as fuel.VTT is conducting a programme of material exposure trialsat the Alholmens Kraft power plant in the city ofPietarsaari. The exposure campaign involves thedeployment of one corrosion probe in a 550 MWthcirculating fluidised bed boiler. Duration of themeasurement campaign was about 1300 hours. The corrosionprobe measurement was performed for samples with fivecoatings: NiCr, IN625, Diamalloy 4006, SHS9172 andNiCrTi. Samples were exposed at two metal temperatureranges of 550 and 750°C, which correspond to both todaysand future steam temperatures of a high-efficiencyboiler. Used reference tube materials were ferritic steelT92 and nickel super alloy A263.Performance validation of the coatings was performed aswell as an indicative analysis of the effects of fuels,deposit properties and boiler process parameters oncorrosion phenomena. Preliminary economic feasibility ofthe use of coatings to extend lifetime of a superheaterwas included. Overall at 550°C the coatings hadnegligible corrosion and at the higher temperature cleardifferences emerged: NiCr and NiCrTi being the topperformers.
