Overview

The DN-2 semi trace steam nitrogen analyzer detects nitrogen in coal, which is an important element in coal. The nitrogen oxides generated by its combustion cause serious air pollution, easily leading to acid rain and soil acidification. At the same time, nitrite is an important carcinogen. In power industry, the determination of nitrogen content in coal can be used to calculate the combustion heat of coal, theoretical combustion temperature, composition of combustion products and heat balance. The semi trace steam nitrogen analyzer in coal testing equipment is also an essential indicator in coal, just like the calorimeter, sulfur analyzer, and coal quality analysis instrument, which are equally important.

Product Details

Principle of Xinda DN-2 semi micro steam nitrogen analyzer: A certain amount of coal or coke sample, under the conditions of using alumina as a catalyst and loosening agent, is introduced with steam at 1050 ℃, and all nitrogen and its compounds in the sample are reduced to ammonia. The generated ammonia is washed with sodium hydroxide solution, distilled, absorbed with saturated boric acid solution, and titrated with standard sulfuric acid solution. The nitrogen content is calculated based on the consumption of the standard sulfuric acid solution.
