3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Coal Combustion agent sulfurfixationagentduringcoalcombustion
Capable of forming a stable solid residue of sulfur in coal chemical reaction in the combustion process and remain in the coal ash, do not bring a new source of pollution
Class to add substance.
3.2
Emissions of sulfur emittedsulfur
Coal sample at a certain temperature complete combustion of sulfur release quality.
3.3
Effective desulfurization rate effectivesulfurfixationrate
Sulfur itself has the ability ABSORBENTS, the specimen before and after the poor quality of the desulfurization agent sulfur emissions as a percentage of sulfur emissions of coal quality.
4 Method summary
Test sample in an air stream of combustion, the sulfur in the sample to sulfur oxides, hydrogen peroxide solution is absorbed to form sulfuric acid, dissolved with sodium hydroxide
Droplet generation of sulfuric acid, sodium hydroxide standard solution according to the volume involved in the reaction of the samples to emissions of sulfur content. At different temperatures
Add sulfur emissions before and after desulfurization agent sample curve ABSORBENTS effective desulfurization rate curve evaluate the effect of desulfurization desulfurization agent.
5 Reagents and materials
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity.
