A boiler exhaust pipe is in tangential connection with a cyclone dust collector, dust is exhausted from a cone bottom through an air-lock valve after cyclone de-dusting, and exhaust enters a cone through a cyclone riser, passes through a tube nest after being uniformly dispersed, and is discharged by an exhaust pipe through an induced draft fan after being centralized by an upper tapered hopper; an impeller of the induced draft fan adopts the structure that blades are shaped like hollow reversed water droplets and a back plate is dish-shaped; the contour line of the induced draft fan is an involute. The tail heat recovery and dust removal integrated coal-fired boiler creatively integrates boiler tail heat recovery and dust removal, and a cyclone dust removal efficient tail heat recoverer is designed to complete tail heat recovery and dust removal in one step, so that the equipment investment is reduced and the working efficiency is improved; as the structure that the blades are shaped like hollow reversed water droplets and the back plate is dish-shaped is adopted, dust on the impeller of the induced draft fan can be cleaned in real time, the impeller strength of the induced draft fan is improved, the stability is enhanced, safety accidents caused by dust accumulation are effectively prevented, and the application prospect is wide.

The invention discloses a condensation water drainage pipe of a wall-mounted furnace. The condensation water drainage pipe comprises a condensation water drainage pipe main body, a large elastic tubeis annularly arrayed on the inner wall of a outer sheath, anti-folding plates are annularly arrayed on the inner wall of the outer sheath, a small elastic tube is annularly arrayed on the outer wall of the condensation water drainage pipe body, and elastic plates are arranged in the inner cavity of the large elastic tube and the inner cavity of the small elastic tube. According to the condensationwater drainage pipe, the pipe is provided with the small elastic tube, the large elastic tube and the anti-folding plates, the bending resistance is improved by utilizing the mutual extrusion pressure of the anti-folding plates, the small-sized elastic tube and the large-scale elastic tube, meanwhile, the impact force and the pressure brought by the outside can be buffered, and the service life of the condensation water drainage pipe body can be prolonged; elastic plates are arranged in the small elastic tube and the large elastic tube, and the elastic buffering capacity of the small elastictube and the large elastic tube is further improved.
