A review on methods of flue gas cleaning from combustion of biomass

Application of renewable energy technology is essential for achieving zero carbon buildings within the timescale envisaged by the UK government and the EU because the carbon intensity of the grid will still be high (well above 70% of current level) by 2016 and 2019. The biomass is a key renewable energy source, but its use in buildings is often affected by the emission of particulates and other pollutants in the waste gas, resulting in significant resistant to the technology by building users. The proposed research investigated various ways of removing pollutants, from the exhaust gas of biomass boilers. The review of literature shows that low cost and low maintenance technologies e.g. cyclones are preferred choices however they come with some limitation in removal of particulates. Recent advances in flue gas cleaning came with novel hybrid solutions to overcome traditionally used technologies for flue gas cleaning. Use of electrostatic preceptors with combination of other technologies is one example. The study found that it is difficult to obtain high removal efficiency for smaller particle range and require combination of technologies and improved hybrid solutions.
