It has a wide variety of industrial burners, industrial burners for conventional boilers, called boiler burners, low nitrogen burners with the view of what is progressive of nitrogen emissions
Low nitrogen burners any better sense of nitrogen emissions
Currently, there are a variety of skills for handling high-temperature nitrogen oxides, comprising: a burner design, exhaust gas or flue gas recirculation. Chemical additives (such as ammonia). The catalyst adjuvant. Burner manufacturers use low nitrogen oxide emissions deflector, flue gas recirculation and air staging and other design. The furnace combustion products (POC) introducing the flame or fuel mixed with air or POC exhaust system, the furnace temperature is then lowered, i.e. can achieve the purpose of flue gas recirculation. Can induce complete combustion flue gas recirculation (POC) from the furnace exhaust flame products or systems using the POC, or fuel mixed with air, the flame temperature drops. May be used to control the speed of reaction of the oxygen, it is also diluted, and then decrease the possibility of oxygen into the nitrogen oxide formation reaction. Furnace temperature control air classification skills of cultural learning environment, and then drop the formation of nitrogen oxides. Low NOx burners are summarized Bloom's low NOx burner covers the range commonly used in industry. It contains direct flame burners and radiant tube burner, combustion air can be used to preheat the combustion air and cold heat exchangers and thermal storage devices occurs. Direct flame burners center is proven spoiler skills. With modern reproduction cold combustion air burner, emission levels of nitrogen oxides, carbon monoxide and carbon dioxide were significantly lower than expected. In the design of the radiant tube, Bloom choice of common engineering approach, when the exhaust gas recirculation burner, heat efficiency or very small loss of only minimal. Low nitrogen burner and low NOx burners, the fuel combustion process refers to low nitrogen emissions from burner, burner selection of low nitrogen emissions of nitrogen oxides during combustion can be lowered. Oxides of nitrogen in the combustion process occurs mainly NO and NO2, generally these two known as nitrogen oxides of nitrogen oxides of nitrogen. Many experimental results show that the nitrogen oxide emissions from combustion apparatus main is NO, even about 95%, while only about 5% NO2.
