Abstract

A water-cooling U-valve is composed of a downcomer (1), a riser (2), and a return chute (3), which are sequentially connected. An intermediate partition (4) is disposed between the downcomer (1) and the riser (2), the lower parts of the downcomer (1) and the riser (2) are interconnected. A material returning partition (5) is disposed between the riser (2) and the return chute (3), the upper parts of the riser (2) and the return chute (3) are interconnected. The casing of U-valve comprises membrane walls, the inside of the membrane walls are laid with refractory. Some water-cooling tubes of the membrane walls extend into the inside of the U-valve, forming the water cooing intermediate partition (4) and material returning partition (5). The headers (40, 50) are connected with the headers (33, 13) formed by some water-cooling tubes of membrane walls by connecting tubes (7, 8).
