| titleOfInvention | Method for determining content of calcium sulfate in sintering desulfurization and denitrification ash |
| abstract | The invention discloses a method for measuring the content of calcium sulfate in sintering desulfurization and denitrification ash, which mainly solves the technical problem that the content of calcium sulfate in the existing sintering desulfurization and denitrification ash can not be accurately measured. The technical scheme is that the method for measuring the content of calcium sulfate in the sintering desulfurization and denitrification ash comprises the following steps: 1) removing calcium sulfite in the sintering desulfurization and denitrification ash, and adding 0.200-0.500 g of desulfurization and denitrification ash sample into a conical flask; then adding 20-30 mL of hydrochloric acid solution with the volume concentration of 50% into the conical flask, and shaking up the sample in the conical flask; 2) extracting sulfate ions in the filtrate, and heating the filtrate containing the sulfate ions in the beaker by using an electric hot plate at the temperature of 80-90 ℃; 3) and calculating the mass content of calcium sulfate in the sintering desulfurization and denitrification ash. The method has the advantages of simple operation, good precision, high accuracy and low detection cost. |
