PURPOSE:To improve heat transfer efficiency by mounting a heat transfer acceleration plate in a radiation heat transfer pipe along its longitudinal direction. CONSTITUTION:A heat transfer plate 6 of, for example, high alumina-contg. bricks, ceramics, mica or the like, is mounted in a radiation heat transfer pipe, for example, steel pipe 1, along its longitudinal direction. As a result, the quantity of the heat transferred from fuel gas into a furnace is increased by the radiation heat transfer from the plate 6 to the inside wall of the pipe 1 and the increase in the convection heat transfer itself of the pipe inside wall. |
