Abstract
The invention relates to a novel boiler smoke afterheat energy saver. The novel smoke afterheat energy saver comprises a boiler smoke discharge system and a boiler afterheat utilization system. A boiler smoke discharge pipeline is arranged at a smoke discharge hole in the rear upper portion of a boiler, a dust extractor is arranged in the middle of the boiler smoke discharge pipeline, a cold-heat exchanger is arranged at the position close to the front end of the boiler smoke discharge pipeline, a boiler afterheat smoke recycling pipeline is arranged at the top end of the cold-heat exchanger, the tail end of the boiler afterheat smoke recycling pipeline is connected with a conical smoke discharge pipeline, an oxygen delivery pipeline is arranged at the front end of the boiler afterheat smoke recycling pipeline, and a smoke guide fan is arranged at the tail end of the boiler smoke discharge pipeline. The novel boiler smoke afterheat energy saver is characterized in that afterheat smoke generated during burning of the boiler is oxygenated and then discharged to the boiler through an oxygen supply fan, secondary burning supporting is realized, heat conduction efficiency is improved, and afterheat smoke is recycled. Meanwhile, dust in the smoke is greatly reduced, environmental purification is facilitated, and dual effects of energy saving and environment protection are achieved.
