Limestone

Product Description

To obtain good diffusion of the heat without hot points, an annular layer of a neutral body can be used, which will not react with the refractory at the level of the injectors. Thus, the annular chute can be charged with particles of calcareous rock or limestone flux, which will form a protective layer along the wall of the furnace. The gases in contact with the air injected by tuyere burn while passing the limestone flux and utilize their sensible heat and their calorific power for the transformation of the limestone flux into lime.
