The SCR is a four-layer silicon device, the layers being alternately p- and n-type semiconductor materials. This structure is referred to as p-n-p-n. Three semiconductor junctions are therefore formed in the device. Figure 4 overleaf is a representation of the layer construction in an SCR. Figure 4 SCR layer constructionApr 14, 2015 · Small and bulk urea deposit samples that formed during engine dyno tests with exhaust temperatures between 200 and 425 °C were analyzed. The results showed that exhaust temperatures of 200-250 °C inside the decomposition tube yielded unreacted urea, biuret and cyanuric acid. However their proportions varied appreciably from test to test.The SCR reactor is located in the tail of boiler (high dust configuration) and the coal used is bituminous coal containing about 0.7 wt.% S from Datong, China.
