Co-combustion - A summary of technology

摘要: Co-combustion of biomass or waste together with a base fuel in boiler is simple and economically suitable way to replace fossil fuels by utilise waste. high-efficiency power station means utilisation higher thermal efficiency than what otherwise had been possible. Due transport limitations, the additional will only supply minor part (less few hundreds MWfuel) energy plant. There are several options: co-combustion coal pulverised fluidised bed boilers, combustion on added grates inserted combustors for coupled parallel steam circuit plant, external gas producers delivering its an oil, burner. Furthermore can be used reburning order reduce NO emissions after burning N2O boilers. Combination give rise positive negative synergy effects, which best known interactions between S, Cl, K, Al, Si that may prevent deposits tubes catalyst surfaces, have influence formation dioxins. With better knowledge these effects ones utilised avoided.
