LIMB Lime/Limestone Injection Into A Multi-Stage Burner
LIMB Lime/Limestone Injection Into A Multi-Stage Burner : A flue-gas desulfurization process used in Germany and Finland. Dry, ground limestone is injected directly into the combustion chamber. This reacts with the sulfur dioxide, and the dry particulate product is collected downstream together with the ash. The process is suitable only for those systems which limit the maximum combustion temperature by staging, in order to minimize the production of oxides of nitrogen
