Natural gas is a mixed gas consisting of hydrocarbons, hydrogen sulfide, nitrogen, and carbon dioxide, etc., which is a combustible gas that is off underground. Natural gas burners can be applied to heating projects, then do you know all kinds of low-nitrogen burners? (one)
Do you know all kinds of low-nitrogen burners? (one)
According to the principle of reducing nitrogen, there are currently four low nitrogen burners: stage combustion type low nitrogen burners, thick low nitrogen burners, self-recirculated low nitrogen burners, and split flame low nitrogen burners. In fact, in our long-lived official website, there is a simple introduction to these four burners. Xiaobian brings some information to everyone, and put some relevant data. Low nitrogen burners are firstly a stage combustion-type low nitrogen burner that is mainly used to reduce combustion temperatures and oxygen concentrations to inhibit NOx. The fuel stage combustion low NOx burner can reduce the amount of NOx, mainly well organized aerodynamic working conditions and mixing of fuel and air. A swirl blade is provided in the burner outlet to achieve a certain swirl strength, the inner surface layer of the fuel is sprayed, so that the fuel is uniformly mixed with one air, partially air to form a fuel over-concentration combat region; in the fuel The unburned combustible combustible combustion in the concentration is mixed with the high-speed outer airflow to form a fuel over-off, and finally complete the combustion process. This combustion method is different from the two-stage combustion, in the fuel concentration, due to the high temperature flue gas reflow, the flame temperature is low, and the air is insufficient, but it can not only suppress the temperature type NOx, but also reduce fuel type. The amount of NOx is produced, and since the entire flame is surrounded by outer rotating airflows, the soot and NO generated in the fuel cross concentration will continue to be burned when the fuel is over light. This burner can reduce the NOx concentration to about 50%. It is then a concentrated low nitrogen burner, and the principle of concentrated low nitrogen combustor is to make a portion of the fuel overflow, and the other fuel is overfold. Due to large air volume, the combustion temperature is inevitably lowered, there is a decrease in temperature type NOx, which is "deviated from combustion" or "non-chemical equivalent combustion". The upper portion of the thick burner is an overfur burner, and the lower portion is a concentrated burner, the air of the two burners, and the fuel is pressed from 22% to 40% and 78% to 60% dispensing. If the deviation ratio is too large, it will cause smoke and NO to increase. The combustion Y-shaped injector is deviated in a nozzle to achieve a strong burning burner is called itself from the combustion oil tunnel. Such an oil tissue can have two arrangements, that is, the size of the spout is divided into a small spout, and the lower half is a large spout arrangement, and the large spout is achieved, and the small spout is overfold. NOx generation amount can be reduced by 20% to 40% compared to general nozzles. The boiler low-nitrogen burner specifically explained that Hebei Qingshan green water undertakes the non-standard custom of various low-nitrogen burners. We have developed non-standard burner shipments have hundreds of sets, customers all over the country, Short delivery time. For more than a decade, we have continuously improved upgrade technology and close to customer needs. Since each case is different, the product requirements and on-site materials are different. We must provide users with appropriate and cost-effective solutions after communicating or actual exploration.
