いという経済的な問題も有している。Nitrogen oxides (hereinafter referred to as NOx), especially nitrogen dioxide (
Air pollution caused by NO2 (hereinafter referred to as NO2) has become a social problem, but in recent years attention has also been paid to indoor pollution caused by NO2. Under these circumstances, conventional indoor open-air heating systems use Bunsen burners or Schwank burners in the combustion section, but it is said that the former Bunsen burners produce a lot of NOx and NO2 in the combustion exhaust gas. Although the latter type of Schwunk burner generates less NOx than the Bunsen burner, the ratio of lNO2 to NOx is high, and it takes time to reach the stable combustion range from the ignition process. -There is also an economic problem in that the cost is high.

なものにすることを目的とする。The present invention eliminates these conventional drawbacks by reducing the amount of NOx and NO2 in combustion exhaust gas, improving the combustion start-up characteristics, and improving safety by providing a semiconductor gas sensor or a solid electrolyte gas sensor. The purpose is to make it better.

媒を設けたものである。In order to achieve this object, the present invention provides a surface combustion combustion system in which a metallic outer cylinder is fixed to the combustion part, and a flame hole made of a cylindrical wire mesh is fixed to the inside of the nuclear outer cylinder by a mixing tube. A semiconductor gas sensor or a solid electrolyte gas sensor is provided in the combustion chamber of the surface combustion burner (lj, a transition metal catalyst is provided directly above the combustion chamber).

Since a uniform all-primary surface combustion flame is formed before and after the combustion, thermal NOx generation is extremely low.

The 1m1 body electrolyte gas sensor makes it possible to control the indoor oxygen concentration and ensure safety in the event of incomplete combustion, extinction, etc.

成されている。In Figure 2, 1 is a nozzle, which faces the mixing tube 2 (7
A metal outer cylinder 3 and a flame hole 4 made of a cylindrical wire mesh are fixed to the mixing tube 2, and sealing metal tubes 6a and 6b are inserted into the combustion chamber 6 through the mixing tube 2. A semiconductor gas sensor or a solid electrolyte scum sensor 7 and a discharge plug 8 are fixed therethrough. The transition metal catalyst 9 is provided at a position where secondary air can be prevented, so that the structure is sealed except for the combustion chamber 5 and the exhaust gas outflow direction. Blower 1o
1. is placed directly on the surface combustion burner 12 via the rectifying plate 11. The hot air passage wall 13 is configured to surround the baffle plate 11, the transition metal catalyst 9, and the outer cylinder 3, and is further configured to be recessed from an exterior body 16 having an outlet 14 at the lower part of the front surface.

It is possible to suppress the generation of CO by cooling the flame hole with air and prevent malfunction of the gas sensor 7. Furthermore, by keeping the transition metal catalyst 9 and the combustion chamber 5 airtight, it is possible to suppress the oxidation of NO2 due to the rapid cooling of the combustion exhaust gas by secondary air, and the transition metal catalyst 9 can be used efficiently. .

という効果が得られる。As described above, according to the hot air heating device of the present invention, a surface combustion burner is used in which a metal outer cylinder and a flame hole made of a cylindrical wire mesh are fixed to the inside of the nuclear outer cylinder with a mixing tube. As a result, it is possible to realize low NOx combustion, which is comparable to that of the conventional method, and also to perform combustion with a fast rise characteristic. The reduced transition metal catalyst reduces NO2 in NOx to NO and oxidizes some CO to CO2, achieving clean combustion. In addition, the semiconductor gas sensor or solid electrolyte gas sensor provided in the combustion chamber has the effect of ensuring various safety features such as oxygen deficiency detection, incomplete combustion prevention, and burnout detection.
