The present invention relates to a warm air and carbon dioxide gas supply device for supplying warm air and carbon dioxide gas to an indoor space such as, for example, a greenhouse or greenhouse. More specifically, the present invention relates to a device where external air supplied through a blower for forming warm air is installed inside. Thermal energy generated from the metal fiber gas burner of the premixed combustion method is directly heated and supplied indoors in the form of warm air, thereby enabling indoor heating, and at the same time, combustion gas generated by combustion by the metal fiber gas burner is supplied indoors. As the carbon dioxide gas (carbon dioxide) contained in the combustion gas increases, the photosynthesis of indoor crops can increase. In particular, the mixed gas of fuel gas and combustion air is split and burned at a uniform air-fuel ratio through the micropores of the metal fiber pad. This relates to a hot air and carbon dioxide gas supply device using a metal fiber gas burner with a premixed combustion method that improves combustion efficiency and reduces the generation of carbon monoxide and nitride oxide, making it safe to use.

In general, hot air and carbon dioxide supply devices are mainly installed in greenhouses or greenhouses, and allow indoor heating by directly heating the outside air supplied through a blower for forming hot air and supplying it indoors through the heat energy generated by burning fuel gas. This refers to a device that promotes the growth of indoor crops by supplying carbon dioxide gas contained in the combustion gas generated from combustion to the indoor space to induce an increase in photosynthesis.

As an example of such a warm air and carbon dioxide gas supply device, Korean Patent Registration No. 10-1174336 (August 16, 2012) includes a burner on one side that burns air introduced from the outside, and a hollow hole in which an induction plate that fixes the burner is fixed. Combustion chamber in the form of a tube; and a front plate coupled to the other side of the combustion chamber and forward, a side wall connected to the front plate, a plurality of bent grooves are formed on the side wall, and a bent portion protrudes from the bent groove, and a space is formed between the plurality of bent portions. A carbon dioxide gas generator equipped with a high-efficiency combustion plate including this formed combustion plate is disclosed.

In addition, Korean Patent Registration No. 10-2217635 (2021.02.19.) discloses a housing having an outlet and an inlet formed on one side and the other side and a space therein; a combustion chamber installed on one side inside the space facing the outlet, forming a discharge port open toward the outlet on one side, and having an opening formed on the other side facing the discharge port; an outer circumference of the combustion chamber; A heat-insulating outer tube installed on the inner circumference spaced apart from each other; a blowing fan installed around the inner circumference of the inlet; a burner installed on the other side of the combustion chamber to ignite the supplied fuel to burn the fuel in the combustion chamber; an external air supply pipe extending from the outside of the housing to the burner and connected to the burner to supply external air to the burner; In the gas heater device capable of controlling the generation and amount of carbon dioxide consisting of a complete combustion induction shield installed facing the discharge port and spaced apart from one side of the combustion chamber, a first side plate is installed on an inner circumference of the opening, and the first side plate is installed on the inner circumference of the opening. A coupling hole is formed in the center of the side plate, the burner is installed in connection with the coupling hole, a plurality of vortex generation inlet holes are formed as radiators around the outer circumference of the coupling hole, and a vortex is induced around the inner circumference of the vortex generation inlet hole. The sides are formed to be inclined; A second side plate is installed around the inner circumference of the discharge port formed in the combustion chamber, and air is installed on the other side of the combustion chamber and air flows into a plurality of vortex generating inlet holes provided in the first side plate by the blowing force of the blowing fan. When the high-temperature heat and combustion gas generated by combustion in the burner are converted into a vortex form inside the combustion chamber and moved from the other side of the combustion chamber to one side, a plurality of radiators are formed on the second side plate of the combustion chamber and an inner radiator is formed. Combustion gas in the form of a vortex and high-temperature heat are discharged through the combustion gas vortex discharge hole, which has a vortex discharge piece inclined around the circumference; Carbon dioxide generation, characterized in that a groove formed in a cone shape in the center of the complete combustion induction shield, a side plate is formed around the outer circumference of the groove, and a vertical standing protrusion is formed integrally with the outer circumference of the side plate. A gas heater device whose amount can be adjusted is disclosed.

As described above, in the case of the conventional warm air and carbon dioxide gas supply device, a forced mixing type burner is applied in which combustion is achieved by structurally mixing the fuel gas and air injected through the fuel nozzle and combustion gas nozzle, respectively, at the burner head. Accordingly, fuel gas and air are mixed and burned at the head of the burner for a relatively short period of time. In this case, fuel gas that is not properly mixed with air is discharged as is, which not only reduces combustion efficiency, but also causes safety problems in that emissions of carbon monoxide and nitrogen oxides increase due to uneven air-fuel ratio.

In addition, in the case of forced-mix burners, the length of the flame is relatively long, so the size of the entire device has to be increased, and due to the characteristics of forced-mix burners, there is also a disadvantage that partial overheating may occur due to the shape of the flame.
