What are the factors that affect the NOx emission concentration
1. Factors affecting denitration efficiency Due to the different quality of coal in different areas, the CO combustion of coal is the same. Therefore, a large amount of flue gas will appear when burning some low heat coal; on the contrary, if some high heat coal is used, the amount of flue gas wi...
What are the differences in conditions, equipment and operation of silver electrolysis in different plants
The vertical electrode electrolyzer invented by Mobius in 1890 is the most widely used one in Europe and other regions. However, the horizontal electrode electrolyzer invented by tume and balbach thum was also used in America. Although the latter has the advantage of dissolving anode completely, ...
