The boiler has a two-layer furnace with water cooling membrane wall, a steam separator, a water cooling circuit connected with the inlet of the separator, and a cooling steam circuit connected with the dry steam output of the separator, including the cooling membrane wall with the steam of the previous kiln.

摘要

A boiler includes a low-temperature furnace, the membrane wall of which is water-cooled, an upper furnace, the membrane wall of which is steam cooled, a steam separator, with fluid input and dry steam output, A cooling water circuit connected to the liquid input of the steam separator to provide wet steam to the steam separator. This is a water cooling circuit, including the film wall cooled in the low-temperature furnace, There is also a cooling steam circuit connected to the dry steam output of the steam separator to receive the steam from the dry steam output,The cooling steam circuit here includes the upper kiln steam cooling film wall.
