Abstract

See full text

The present invention is such that, with H1 being the height from a slurry outlet to a control liquid level, H2 being the height from the control liquid level to the top of a flash vessel, and being the diameter of the flash vessel, 0.35D≦H1≦0.45D, and 0.75D≦H2≦0.85D, and at least one liquid level sensor detects a slurry liquid surface at a control liquid level; when the liquid level sensor detects a slurry liquid surface which has risen, a slurry discharge valve installed on a slurry discharge pipe derived from the flash vessel is opened; and when the liquid level sensor detects a slurry liquid surface which has fallen, the slurry discharge valve is closed, whereby opening and closing of the valve is appropriately controlled thereby to reduce troubles with a steam discharge pipe, the slurry discharge pipe, and the slurry discharge valve.
