链条炉脱硝控制原理选择什么样的厂家

Denitrification combustion control principle The mechanism of nitrogen oxides generating nitrogen during combustion usually includes three types: 链条炉脱硝控制原理选择什么样的厂家， thermal, fuel and instantaneous. The decisive factor in the oxide generation of thermal nitrogen is temperature, which is generally thought to be very small at temperature of 1500K. The principle of denitrification combustion control technology is to try to establish the burning area of oxygen-rich fuel, to reduce the temperature of local high temperature area, to reduce the oxygen concentration in the combustion area, etc. Nitrogen oxide emissions can be reduced by changing combustion conditions and burner structure to achieve the above objectives, including low oxygen combustion, air graded combustion, fuel graded combustion, flue gas recirculation, low nitrogen burner and other methods. These methods can reduce the nitrogen oxide in the flue gas by 20% to 60%. Fluigasdenitrification technology, the current flue gas denitrification technology is a wide variety of, according to the denitrification process whether to add water and denitrification products of the wet and wet form, flue gas denitrification is divided into wet flue gas denitrification technology and dry flue gas denitrification technology. In recent years, Hebei Yaoyi to comply with the national "resource-saving, environment-friendly" policy requirements, always adhering to the "technology-oriented, realistic innovation" business purposes, the scale of business continues to expand, our company in the country has a number of typical project cases. For boiler denitrification, boiler furnace denitrification technology belongs to the new technology, HNCR technology investment cost is low, construction cycle is short, denitrification efficiency is high, the most important is the low cost of late operation.

脱硝燃烧控制原理
燃烧过程中生成氮的氧化物的机理通常包括热力型、燃料型和瞬时型3种。热力型氮的氧化物生成的决定因素是温度,一般认为温度<1500K时,氮的氧化物生成量很小。脱硝燃烧控制技术的原理就是设法建立缺氧富燃料的燃烧区域、设法降局部高温区温度、使燃烧区氧浓度适当降等。在燃烧过程中可通过改变燃烧条件和燃烧器结构以达到上述目的来降氮的氧化物的排放, 包括氧燃烧、空气分级燃烧、燃料分级燃烧、烟气再循环、氮燃烧器等方法。这些方法可使烟气中氮的氧化物降20%~60%。烟气脱硝技术，目前烟气脱硝技术种类繁,按脱硝过程是否加水和脱硝产物的干湿形态,烟气脱硝分为湿法烟气脱硝技术和干法烟气脱硝技术。近年来，河北耀一遵循“资源节约型、环境友型”的政策要求，始终秉承“技术为本，求实创”的企业宗旨，业务规模不断扩大，我公司在国内拥有项典型项目案例。对于锅炉脱硝，锅炉炉内脱硝来说，HNCR炉内干法脱硝技术属于技术，HNCR技术投资成本，建设周期短，脱硝，链条炉脱硝控制原理选择什么样的厂家，主要的是后期运行费用。
