Large scale power plant boiler co-combustion advantage

Co-combustion in large scale power plants can lead to an overall saving of fuels in comparison to independent fossil and biomass fired plants. Also, it can increase the fuel flexibility and reduce investment cost. Comparing with coal, biomass is a renewable energy source, which is considered as a CO2 neutral fuel with lower emissions of SO2, NOx, heavy metals. NOx emissions could be reduced by biomass, which has a lower nitrogen and high volatile content.  A high efficient biomass cogeneration boiler can meet your requirement on industry.

1. Reducing greenhouse gases emission- biomass is considered as a “ carbon neutral” fuel in the co2 emitted during biomass combustion is equal to that absorbed during the biomass growing. When biomass displaces a fossil fuel, a net reduction in greenhouse gas emissions is achieved.
2. Reducing local air pollutant emissions-burning biomass instead of fossil fuel results in lower emissions of SO2 and NOx.
3. Increasing electrical efficiency- the electrical efficiency of co-combustion power plant is higher than the traditional biomass plant, which has a small scale.
4. Ensuring security of supply- there exists a wide range of usable biomass fuels. Varying qualities and quantities of fuel can be partially compensated by adjusting the co-combustion rate.
5. Reducing cost- co-combustion presents the opportunity to use the existing fossil fuel fired power plant infrastructure, which can be modified for co-combustion relatively easily. An optimum thermal biomass blending ratio of biomass co-combustion is 10%. Addition of biomass to a coal fired boiler does not impact or at worst only slightly decrease the overall generation efficiency of a coal fired power plant. Compared with other renewable options, biomass co-firing represents the most cost effective means of renewable power generation in many cases.
