Zusammenfassung:	The utility model provides a low-heat value fuel boiler with a spiral-fin slag-bonding pipe structure, and the boiler is characterized in that a furnace cavity is connected with an outlet collection box of a slag-bonding pipe; the outlet collection box of the slag-bonding pipe is connected with a spiral-fin slag-bonding pipe; the other end of the spiral-fin slag-bonding pipe is connected with a rear water-cooling wall outlet collection box through a three-way joint; and the rear water-cooling wall outlet collection box is connected to a rear smoke channel. The boiler can solve the problems that a conventional low-heat value fuel boiler is insufficient in evaporation and heat absorption and is high in smoke evacuation temperature, and reduces the metal consumption.
