Fireside Corrosion Of Boiler Tube Materials - Effects Of Co-Firing Biomass With Coal: Project Summary

This resource links to a document we hold in our system

Abstract:

The objectives of this project were:

  • To determine the effect of co-firing biomass with coal on boiler tube fireside corrosion rates in existing subcritical coal fired power plants.
  • To determine the likely fireside corrosion rates that could be expected on boiler tubing in future advanced (ultra) supercritical power plant.
  • Typical and potential boiler tube alloys have been exposed to simulated furnace wall and superheater/reheater environments in the 1MWTh Combustion Test Facility (CTF) at Power Technology.

    A total of four nominally 50 hour duration exposures have been completed. Specimens were exposed to a range of metal temperatures, heat fluxes and gaseous environments, representative of pulverised coal combustion under low NOx conditions with biomass additions. Biomass was co-fired with Daw Mill coal on 20% and 10% thermal or heat input basis (approx 35% and 17% by mass). Specimens were exposed to the combustion environment on air-cooled, precision metrology, corrosion probes.
