[0002] Currently, most tobacco flue-curing rooms use air-source heat pumps as a heating source. While air-source heat pumps are more environmentally friendly than biomass burners, they also have significant drawbacks. A power outage can render the entire room inoperable, significantly reducing flue-curing efficiency. Using biomass burners as a heating source is not environmentally friendly in the long term, so a flue-curing room with dual heating sources is highly desirable. Utility Model Content

[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.
[0011] like Figure 1 As shown, a tobacco flue-curing room with dual heating of a combustion furnace and a heat pump comprises a tobacco flue-curing room 1, a burner 2, an air source heat pump 3, a heat exchanger 4, a circulating fan 5, a dehumidifying fan 6 and a sealed door 7. A front partition 11 is provided at the front end of the tobacco flue-curing room 1. The front partition 11 divides the inner cavity of the tobacco flue-curing room 1 into a heat source chamber 12 and a tobacco flue-curing chamber 13 arranged in front and back. A plurality of tobacco hanging rods 16 are arranged horizontally in the tobacco flue-curing chamber 13. The top and bottom edges of the front partition 11 are spaced apart from the top and bottom walls of the tobacco flue-curing room 1 respectively. A circulating fan 5 and a heat exchanger 4 are installed in the heat source chamber 12 from bottom to top. The heat exchanger 4 is connected to the air source heat pump 3.
