Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a special energy-saving device for a boiler comprises an energy saver 1, wherein a plurality of sections of spiral finned tubes 2 are embedded in the energy saver 1, the overlooking surfaces of the spiral finned tubes 2 are in a plurality of continuous S-shaped arrangements, the surface area of the spiral finned tubes 2 in the energy saver 1 is increased, the spiral finned tubes 2 are communicated with one another, the bent ends of the spiral finned tubes 2 penetrate through the side wall of the energy saver 1 and are positioned outside the energy saver 1, the high-frequency resistors 3 are wrapped outside the horizontal ends of the spiral finned tubes 2, two ends of the spiral finned tubes 2 penetrate through the outer wall of the energy saver 1 and extend to the outside of the energy saver 1 respectively, two ends of the spiral finned tubes 2 are communicated with a water inlet pipe 9 and a water outlet pipe 10 respectively, the water inlet pipe 9 and the water outlet pipe 10 are arranged in a plane-centered symmetry manner relative to the energy saver 1, the water inlet pipe 9, because the hot air floats upwards, the spiral finned tube 2 at the top is not contacted with the flue gas with higher energy at the top, and the spiral finned tube 2 at the bottom is contacted with the flue gas with lower energy at the bottom, so that a better energy conversion effect is obtained.

Specifically, as shown in fig. 1 to 3, an air inlet 4 is communicated with one end of the bottom of the economizer 1, and air outlets 5 are communicated with both horizontal ends of the top of the economizer 1.
