The invention provides a water pipe heating pipe residual heat boiler system arranged in a sintering machine flue and relates to the technical field of steel smelting equipment. The water pipe heating pipe residual heat boiler system comprises a large flue and a small flue of a sintering machine, a large flue heat pipe type evaporator, a small flue heat pipe type evaporator, a large flue primary water pipe type evaporator, a large flue secondary water pipe type evaporator, a small large flue primary water pipe type evaporator, a small flue secondary water pipe type evaporator, a steam pocket and a water feeding system, wherein the large flue and the small flue are provided with a plurality of gas guide pipes respectively. According to the water pipe heating pipe residual heat boiler system, the water pipe type evaporators and the heat pipe type evaporators are divided into a plurality of heat exchange modules to be directly arranged on the large flue and the small flue of the sintering machine, so that the reasonable and effective gradient utilization of energy sources is realized; equipment investment is saved and an occupied area is small; respective advantages of the water pipe type evaporators and the heat pipe type evaporators are fully played in a use process; the flue gas residual heat is recycled to the greatest extent; meanwhile, the production of the sintering machine is not influenced and the water pipe heating pipe residual heat boiler system can be widely applied to the industry of a steel enterprise sintering machine.
