New ideas, small cost brings great benefits! Recently, Hefei Debo's "research and development of low-carbon technology for biomass gasification of coal-fired units and indirect CO combustion of coal" won the 2021 electric power science and Technology Innovation Award! As long as you have a coal-fired unit, you can use biomass gasification technology to increase the proportion of green and low-carbon energy at a very small cost. Add a set of biomass gasifier near your coal-fired unit to send biogas to the original coal-fired unit to realize mixed combustion!
