。However, such conventional books do not have the same smell.
Because the combustion temperature of burner fal is high, a relatively large amount of NOx is generated.
In addition, there are safety and hygiene disadvantages in that combustion exhaust gas is generated and released into the interior, and the combustion exhaust gas is high temperature and its flow is directed only upward (so-called upflow). Therefore, in order to improve the exhaust heat recovery efficiency, the vertical height of the heat exchange section +01 (41) must be considerably increased, and since it is an exhaust gas upflow type, the condensing type It was difficult to treat condensed water in the heat exchanger (1) and the exhaust gas cutoff board 1e).

The purpose is to use a low-temperature combustion burner that generates little NOx, and to make the heat exchange part as compact as possible, while also achieving efficient exhaust heat recovery through condensation. We are trying to develop a gas tanker with a completely new configuration that can process water relatively easily.

というように、種々の利点がある。The infrared heating type exhaust gas downflow type gas water heater has all the above features and features, and has the following functions and sound effects. In other words, as the heating device uses an infrared radiant burner that burns at a low temperature and radiates a large amount of infrared rays, the amount of harmful NOx generated is extremely small.
It is safe and sanitary, and (a) all the combustion exhaust gases from the burner are guided from the inner ascending path to the outer descending path and discharged. Although the height of the heat exchange part in the vertical direction is very small, the efficiency of heat recovery from the radiant heat from the low-temperature combustion type infrared radiant burner and the heat retained in the combustion exhaust gas is improved. (1) Direct the combustion exhaust gas downwards using the downflow method.
In other words, since a configuration is adopted in which the exhaust gas is discharged near the mixing pipe of the burner, the exhaust gas is also sucked in as the combustion air is sucked into the mixture/α, and the NOx due to exhaust gas recirculation is As mentioned above, all heat recovery vehicles are of the high exhaust gas flow type, so it is necessary to install a top plate to cut off the exhaust gas, unlike the conventional one: 1ilC< ,Also,
Since the condensed water mainly generated in the outer cylindrical part falls downward in the same direction as the exhaust gas discharge direction, for example, condensed water can be treated with a simple structure that only requires a plate to stop the metal receiver. , there are various advantages.

できる。In addition, if the combustion section is configured to have a double structure consisting of an inner cylindrical porous ceramic body and an outer cylindrical porous ceramic body surrounding the inner cylindrical porous body, the ignition can be maintained even more stably, and the turn The down ratio can be increased, and
If a large number of holes are bored in the peripheral wall of the inner cylinder, the infrared radiation from the burner can be transmitted to the side cylinder, further improving heating efficiency, and the bottom of the combustion and exhaust gas can be further improved. Exhaust gas is recirculated from the exhaust road side to the ascending road side, that is, the combustion section, so that the NOx reduction effect can be improved.
