Problems solved by technology

[0004] But, with regard to the far-infrared radiating machine in the past, since the gas passing through the far-infrared radiating tube is discharged into the atmosphere from the chimney as the exhaust gas, although a large amount of cooling air is used, the defect of increasing heat loss is brought.
Not only that, but the combustion of the burner cannot be carried out at high temperature, which will inevitably be accompanied by the generation of NOx. As a result, the conventional far-infrared emitters have brought about the negative impact of exhausting these NOx from the chimney to the atmosphere.

Embodiment

[0024] use as figure 1The multistage far-infrared radiation machine of the described structure carries out the kerosene combustion test. 1.96 liters of kerosene is supplied to the burner combustion device 1 and 0.98 liters of kerosene is supplied to each catalytic combustion device 7 and 8 per hour. Moreover, the blower 3 is used to supply 52Nm to the burner combustion device 1 every hour. 3 The air used is part of the air used as cooling air, the apparent air ratio of the burner combustion device is 3.0, and the combustion temperature is 900°C. And, let the multi-stage far-infrared radiation machine operate under these conditions, at this time, the inlet gas temperature of each catalytic combustion device is 400°C, the humidity air ratio is 5.9, and the combustion temperature is 850°C.

[0025] In the above-mentioned combustion test, Table 1 shows the gas analysis values ​​discharged from the far-infrared radiation tube 6c located on the most downstream side. In order to c...

Abstract

The present invention provides a nuisanceless multistage far-infrared radiation machine with less heat loss of exhaust gas. A far infrared rays radiating tube at the outlet port of combustion gas of a catalyst combustion device of a burner of the multistage far-infrared radiation machine, is connected in series to one or two heat generating units, provided with a far infrared rays radiating tube at the combustion gas outlet port of a burner combustion device.

Description

technical field [0001] The invention relates to a far-infrared radiating machine used as a heating device in a large space such as a gymnasium, an indoor arena, a factory, or an open space such as a golf training ground. The heating device formed by the far-infrared radiating tube arranged above and the heating device formed by the far-infrared radiating tube arranged on the combustion gas discharge passage of the catalytic combustion device are connected in series to form a multi-stage far-infrared radiating machine. Background technique [0002] Far-infrared heating is a very efficient heating method, which can directly heat the object to be heated even in the absence of heat media such as air. Therefore, in the occasion of heating a large space or an open space, a far-infrared radiating machine is widely used. This far-infrared radiating machine will be used to burn fuel that is cheaper than electricity as an energy source together with air in a burner. The burner combus...
