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 in which 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 fuel gas supplied from an external fuel gas source and the combustion air supplied through the combustion air blower are premixed. The premixed combustion method improves combustion efficiency and reduces the generation of carbon monoxide and nitride oxides, making it safe to use as the mixed gas produced by mixing is divided 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.

In general, warm 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.

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.

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.
