Abstract
PURPOSE: To considerably reduce the production of NOx by controlling the grain sizes and compositions of sintering compounding raw materials.
CONSTITUTION: Fine powder portions of less than 1 mm in grain size are contained more than 25% in sintering compounding raw materials. At this time said fine power portions are used by controlling their basicity (Cao/SiO2) to more than 2. Thereby, Nox conversion may be reduced by as much as 30 to 40% than ordinary methods.
