The pipe level of superheater is set, and superheater is made up of the first superheater 2, the second superheater 3 and the 3rd superheater 4, by setting
Three groups of superheaters are put, vapor (steam) temperature can be controlled and prevent that flue-gas temperature reduction is too fast, in case bioxin is generated.
As shown in figure 1, the influent header of the first superheater 2 connects the saturated vapor output channel of drum 1, the first superheater
2 outlet header connects the influent header of the second superheater 3 through the first attemperator 6, and the outlet header of the second superheater 3 is through second
Attemperator 5 connects the influent header of the 3rd superheater 4, the outlet header connection main steam line of the 3rd superheater 4.Outlet header
Pipeline between influent header for superheater.
Flue collector above combustion chamber above the first flue with connecting, with being connected below the second flue below the first flue,
And dust content can be so reduced, the second flue is sequentially provided with from top to bottom provided with mechanism of gathering dust in connection position bottom
First superheater 2, the second superheater 3 and the 3rd superheater 4.
In order to be accurately controlled vapor (steam) temperature and flue-gas temperature, the confession of three layer of first attemperator 5 of attemperator 6 and second
