Abstract
A radiant heat recovery heater includes U-shaped heat transfer tubes each including a first path and a second path arranged on a mounting section. The U-shaped heat transfer tubes are housed in a container fixed to the mounting section. The first paths and the second paths of the U-shaped heat transfer tubes are arranged on the mounting section at equal intervals with a pitch angle θ. The first paths are each arranged on the mounting section at a position offset from the pitch angle θ for the associated second path by a predetermined angle α, so as not to completely overlap a projection of that second path, the projection extending from the container toward the center C of the container.
