Model:KR-N6
The KR-N6 nitrogen in coal analyzer is developed by our company in accordance with GB/T 19227-2008. It has the advantages of intelligent setting of the constant temperature zone of the hydrolysis furnace, fast analysis speed, simple operation steps, and accurate measurement results. This nitrogen content testing equipment is widely used in coal, electric power, metallurgy, environmental protection, commodity inspection, teaching and other fields to determine the nitrogen content in coal and coke, graphite and graphitized petroleum coke.
Nitrogen is an important element in coal. Nitrogen oxides produced by its combustion cause serious air pollution and are easy to form acid rain, which acidifies the soil. At the same time, nitrite is an important carcinogen. In the power industry, the determination of nitrogen content in coal can be used to calculate the combustion heat of coal, the theoretical combustion temperature, the composition of combustion products and the heat balance.
