Co-firing of biomass in coal-fired utility boilers . The co-firing tests were successful in many ways, but the behaviour of the coal mills caused some problems, and therefore the simultaneous feed will not be the solution in a long-term use. Fortum has developed a new concept for co-firing coal and biofuels in large pulverised-coal fired boilers.
Biomass co-firing has been used in Europe and the Netherlands in particular for over a decade. Full-scale commercial co-firing of at least 10 percent biomass (based on heat input) is a daily practice, with a wide variety of bio-fuels and co-firing configurations. The technology of co-firing has been demonstrated in many boilers types in Europe.
2003-6-1 · By cofiring biomass with coal, a continuous supply of biomass would not be an issue, since the boiler plant would always have the primary fuel, coal, for 100% utilization. Cofiring biomass with coal, in comparison with single coal firing, helps reduce the total emissions per unit energy produced.
