摘要：NOVELTY - A whole wet-back fuel/gas boiler of shell type water-fire tube has longitudinal water pipe set in its internal furnace, the bottom of hearth and the shell bottom are linked through short fire tube, the whole wet-back shell, the hearth bottom and the shell bottom the internal furnace are heating surfaces. There is entrance hole at the burning port of the top internal furnace; the flame is parallel with the longitudinal water pipe. The flame and fume is discharged from the boiler through heat convection of the second backhaul flue header after radiation heat transfer with the water pipe, internal furnace, short fire tube and the shell bottom. The utility model has rational structure, high thermal efficiency, low temperature of smoke exhaust, reduced cost and convenient maintenance; it is applied to vertical fuel (gas) hot water and steam boiler.
