If the biomass burner equipment is insufficient during the work, it is easy to cause an abnormality in the burner, what should I do? What are the classifications of low nitrogen oxide burners together?
What are the classifications of low nitrogen oxide burners?
Low nitrogen burners are an important equipment for industrial furnaces that ensure that fuel stabilizes fire combustion and fuel complete combustion, etc., it is necessary to inhibit the amount of nitric oxide must be started from the burner. So what are the classifications of low nitrogen oxide burners? We are specific to the professionals to specify! Depending on the combustion technique of reducing nitrogen oxide, the low-nitrogen oxide burner is roughly divided into the following categories: 1. Stage combustor is designed with low nitrogen burners designed according to the grading combustion principle, so that the fuel and air segmented burn, due to combustion deviation theory The equivalent ratio, so it can reduce the production of nitric oxide.瑄瑄 Burner 2. The self-recirculating burner is an indiscriminate burn that combusts the air to burn some combustion to the burner, and combustion with the air. Due to the recycle of flue gas, the thermal capacity of combustion flue gas is large, the combustion temperature is lowered, and nitric oxide decreases. Another self-recirculating burner is to enter partial flue gas into the recycle in the burner, and the combustion process is added, and the burner is inhibiting nitrogen oxide and energy saving dual effects. 3. The principle of the thick burner is to make a portion of the fuel to be concentrated, and the other fuel is faded, but the overall air volume remains unchanged. Since both parts are blended from the chemical equivalent ratio, nitrogen oxide is low, which is also referred to as deviation of combustion or non-chemical equivalents. 4. Split the flame-type industrial low-nitrogen burner whose principle is to divide a flame into several small flames, and due to the large heat dissipation area, the flame temperature is low, so that "thermal reaction NO" has decreased. In addition, the flames shortened the residence time of oxygen and nitrogen and other gases in the flame, and there is a significant inhibition of "heat reactions NO" and "fuel NO" 5. The mixed promotion burner flue gas is in high temperature zone residence time is One of the main factors affecting the amount of nitric oxide, improve the mixing of combustion and air, so that the thickness of the flame surface is thinned, in the case where the burning load is constant, the flue gas is shortened in the flame surface, that is, the residence time in the high temperature zone is shortened, and thus The amount of nitric oxide is lowered. The mixed promoting combustor is designed in this principle.瑄瑄 burner 6. The pre-combustion chamber of the low nitric oxide pre-combustion chamber burner is a high efficiency, low nitric oxide grading combustion technology in my country in the past 10 years. The pre-combustion chamber is generally mainly treated (or secondary wind) Composition, fuel injection system, etc., fuel and primary wind are mixed, and fuel mixtures are formed in a combustion zone in the pre-combustion chamber. Because of hypoxia, only partial fuels are combustion, fuel is in a flame area with lower guanoxidation and flame temperatures. The precipitation of volatile, thus reducing the production of nitric oxide.
