A gas hot air furnace is here to teach you how to reduce your gas consumption!

The national level of natural gas supply and demand pattern attaches great importance to the coal to gas policy more targeted, such as in the supply of natural gas required to ensure that the first "2 + 26 cities", in these key cities to prioritize the protection of last year has been converted to coal gas users, such a policy to make the upstream enterprises have a soft landing platform. In the face of such a situation, natural gas as the main fuel gas hot air furnace how to reduce gas consumption:

1. Improve the conditions of airflow encounter: improve the gas hot air furnace gas and air two streams of airflow conditions, the purpose is to increase their contact area. The larger the contact area, that is, the larger the reaction area, strengthening the combustion. Specific methods, gas and air can be divided into a number of streams, so that the two streams have a certain speed and cross the encounter; Ger a stream of gas (usually gas) through and submerged in another stream, and so on.

2. Strengthen the mixing, perturbation: gas hot air furnace combustion of gaseous fuels combustion is a single-phase reaction, ignition and combustion than solid fuels easy, but its combustion rate and combustion of the perfect degree of gas and air mixing good and bad relationship is close. The better the mixture, the more rapid and complete combustion, the flame is also short. Therefore, as long as the stability of the flame is not destroyed, should try to improve the airflow outlet or combustion chamber in the air velocity, and even set up at the entrance of the baffle and other resistance obstacles, so that it presses the strike, punch the flame, increase the disturbance of the airflow to strengthen the mix.

3. Preheating gas and air: improve the temperature of gas and air, can strengthen the combustion reaction. Therefore, the exhaust should be used to preheat the gas and air temperature, thereby increasing the combustion temperature and flame propagation speed, so that the combustion process can be strengthened.

4. Rotating and circulating gas flow: to promote the rotation of gas flow can strengthen the disturbance and mixing. At the same time, in the center of the rotating airflow will form a reflux zone to guide a large number of flue gas reflux, circulation, both to strengthen the mixing, but also to extend the flue gas in the gas hot air furnace flow routes and stay time and reduce the incomplete combustion losses.

5. Flue gas recirculation: In order to improve the gas hot stove combustion reaction area of the temperature, a part of the high-temperature flue gas can be led to the combustion according to, so that the end of the combustion or combustion is burning the combustible mixture mixed to improve the intensity of combustion. However, it should be noted that the amount of flue gas recirculation should not be too large, otherwise it will be too much inert material and dilute the combustible mixture hook, but to slow down the combustion rate, or even lack of oxygen pyrolysis, resulting in incomplete combustion loss of gas hot air furnace.
