The combustion heat energy of energy-saving gas burner is mainly composed of radiation energy and convection heat energy. Because of the heat transfer characteristics of radiation, it has a strong penetrating power to the heated object, and its heat is easily absorbed by the heated object, so it has the advantages of high thermal efficiency and energy saving. Radiation energy accounts for about 50%-60%, and the combustion energy of atmospheric burner products is mainly convection energy, and radiation energy only accounts for a small part. Convective heat transfer is carried out by the temperature difference and residence time between the flowing heat (hot air, flame) and the heated object. Because of its short residence time, it consumes a lot of convective heat, greatly reducing the heat received by the appliance and making the thermal efficiency low.
Second, environmental protection and health.
Because the energy-saving gas burner adopts the complete primary air premixed combustion mode, the air required for combustion is completely from the injected primary air, and the proportion of primary air is large, and the combustion is complete, and the carbon monoxide content in the combustion flue gas is very low. As we all know, carbon monoxide and nitrogen oxides are toxic and harmful substances. If the content of carbon monoxide and nitrogen oxides in the air is too high, it will poison people and endanger people's lives in serious cases. The harmfulness of nitrogen oxides is much higher than that of carbon monoxide, and its toxicity is more than ten times that of carbon monoxide. It must be controlled well to achieve the effect of environmental protection.
