Pulverised biofuels flame propagation in comparison to coals

High emissions from burning of fossil fuels and their adverse environmental effects are serious issues that are discouraging their use in the power generation plants. The harmful gases like Carbon dioxide, Nitrogen dioxide and Sulphur dioxide return to land, as acid rain, that is a serious threat. UK relies heavily on the coal power generation plants and around 31% share of electricity was generated from existing coal power generation plants. The coal, in these plants is replaced by renewable biofuels for sustainable power generation. Utilization of coal for generation of electricity has fell down to 36% in 2014 compared to 2013. As a result, the overall emission to be decreased to 45 million tonnes of carbon dioxide that is 9.7% reduction in 2014 compared to 2013 (DECC, 2015). However, there are scarce data of combustion properties for the biofuels. The exploitation of biomass materials in place of coal require detailed investigation of their properties of flame propagation for retrofitting of existing coal power plants which is the aim of this work.
