30 states ( the District of Columbia) have mandated, or enforceable, renewable portfolio standards (RPS). Another seven states have voluntary goals for renewable energy.Coal consuming utilities and industrial are exploring biomass as an option for RPS compliance. Biomass is expected to be the largest source of renewable energy ~ comprising 6.4% of the targeted 15% RES by 2020 according to JP Morgan.Biomass co-firing boiler has the potential to reduce emissions from coal-fueled generation, without substantially increasing costs or infrastructure investments. Research has demonstrated that, when implemented at relatively low biomass to coal ratios, there are significant reductions in energy consumption, and solid waste generation, as well as reduced emissions. However, the nature and chemical makeup of biomass fuels can lead to significant cost increases, maintenance problems, boiler slagging and fouling issues, increased boiler corrosion, and decreased efficiency if biomass use is not very closely managed.There are three types of co-firing in use around the globe1.Direct Co-firing is the simplest of the three and the most common option chosen. In this version of co-firing, more than one type of fuel in a furnace/boiler at the same time. The same, or separate feed systems, mills, and burners can be used depending on the fuel characteristics2.Indirect co-firing biomass is converted from a solid fuel to a gaseous form before firing. The gas is then burned in the same furnace/boiler as the coal3.Separate biomass boiler a separate biomass boiler is added to the overall system to bolster the steam capacity of an existing coal boiler.Why use biomass co-firing?The primary reason for co-firing coal with biomass is as a means of reducing the potential environmental impacts associated with the combustion of fossil fuels.Who can use biomass co-firing?Given that co-firing requires large amounts of biomass fuels, co-firing typically works best with large coal-fueled utilities that have materials handling capability already on site. However, other industrial users cement plants, heating plants, etc. could also make use of biomass co-firing.Biomass costs compare very favorably to other renewable optionsThe addition of biomass to a coal-fueled boiler is not likely to, or will, at worst, have only a minimal negative impact on generation efficiency (depending on fuel preparation measures taken)With proper fuel selection and management, overall emissions of SOX, NOX, and mercury, as well as and net GHG emissions can be reduced. Biomass is typically nearly free of sulfur and mercury, so these emissions are reduced in proportion to its use (NOX emissions may fall or rise slightly depending on boiler operation) . Biomass is considered to be carbon-neutral, so its use can have a proportional reduction in GHG emission.
