In a furnace wall heat-transfer pipe unit in a spiral wound-type boiler, for distributing gas-liquid double layer fluids from lower part spiral pipes to upper vertical pipes, a horizontal pipe is interposed between the spiral pipes and the vertical pipes and extends in a horizontal plane around the furnace wall. The gas-liquid double-layer fluids flow into the vertical pipes via the horizontal pipe extending around the furnace wall from the lower part spiral pipes. Uniform layers of the fluid flow into each vertical pipe so as to minimize an imbalance of fluid temperature at the outlet of the furnace.
