Biomass fuels offer very attractive options for fossil fuelled boilers, with reduced level
of Carbon-di-oxide emission. In many parts of North America provincial regulation on restrictions of
Carbon-di-oxide emissions level are compelling the electric utilities to explore and switch to more
and more of biomass Fuels. Many utilities are exploring the options of firing biomass of either firing
biomass either as co-firing with coal or completely switching over to biomass fuels on the existing
boilers.
However depending on their origin, biomass fuels could be corrosive and have potentials to cause
fouling and corrosion at the usual operating temperatures of conventional Pulverized Fuel boilers.
This proves to be a challenging task to design and maintain such boilers to get the desired level of
efficiency.
