| 摘要 |
The present invention relates to a boiler including a multilayer heat plate furnace smoke tube having superior heating efficiency and reduced volume. The boiler includes: a furnace smoke tube (2) including at least two electric plates (1) stacked onto one another and including at least two uneven pleats (11), a burner insertion hole (12), and an exhaust hole (13); and a pressure container (31) that is insulated from the outside so as to serve as a water chamber (32) by being filled with water. The furnace smoke tube (2) is vertically disposed within the water chamber (32). The furnace smoke tube (2) is heated by a directional spray flame of a burner (51) directly inserted into the furnace smoke tube (2), and the water within the water chamber (32) is heated through an external electric surface of the furnace smoke tube. The multilayer heat plate furnace smoke tube may be significantly reduced in size so as to occupy a small amount of space when installed as compared to a conventional boiler having the same heating capacity. Also, the boiler may have an increased hot water and steam generating rate due to the high heating efficiency and quick heat transfer thereof, and the manufacturing costs of the boiler may be reduced. |
