Oct 22, 2019 · The payback time for the biomass boiler system is 6 years if replacing a natural gas boiler (Table 6). If replacing oil and coal boilers, the payback time is 3 and 4 years, respectively, and for the electric boiler, it is less than 2 years. This is estimated by dividing the capital investment by the average annual net income.Boilers: Economic Change From Coal to Biomass Torrefaction, pelletization and gasification can offer viable and economic means to convert coal- or oil-fired boilers to biomass.

For the carbon footprint analysis, all the sources of emissions in the system have to be primarily defined. In the observed power plant co-firing system (), it is clear that the emissions are caused by the coal combustion (CO 2,co [kgCO 2 /yr]) and various transportation processes.As mentioned previously, it is considered that all the carbon-dioxide emitted from biomass combustion is used by .The changes mean new, dedicated plants using imported biomass will see their support fall from 1.5 REC/MWh to 1 REC/MWh, while new cofiring and coal-to-biomass conversion projects using imported wood will now receive no support at all.
