Description
Изобретение касаетс способов сжигани топлива и может быть исиользовано дл снижепи концентрации окислов азота в газообразных продуктах сгорани , в частности, в котельных агрегатах, оборудованных горелка .ми Известны способы сжигани топлива в котельных агрегатах, в которых часть горелок котла работает с недостатком воздуха .а остальна часть -с избытком его 1. Однако такие способы сжигани обладают сложностью регулировани соотношени расхода воздуха на горелки и усложн ют услови эксплуатации агрегата. Кроме того, ухудшаетс качество сжигани топлива вследствие разрыва между основным и дополнительным факелами горелок, в результате чего повышаетс содержание сажи и окислов азота в продуктах сгорани . Также известны способы сжигани топлива, осуш,ествл емые в горелке нутем одновременной подачи компонентов горени двум потоками в зону сжигани , один из которых вл етс богатой топливовоздушной смесью 2. Недостатками таких способов сжигани топлива , когда все топливо сгорает на первой стадии, а затем продукты сгорани догорают в потоке пр моточного воздуха, вл етс высока температура пламени, а также длительное врем пребывани в зоне горени , что приводит к повышенному содержанию окислов азота в продуктах сгорани . Цель изобретени -снижение содержани окислов азота в продуктах сгорани . Это достигаетс тем, что богатую смесь подают с а 0,5-0,8, а вторым потоком подают бедную топливовоздушную смесь с « 1,3-1,6, где л - коэффициент избытка воздуха. Кроме того, в потоки бедной и богатой смесей могут быть введены инертные газы, а также может впрыскиватьс инертна жидкость , например вода. По предложенному способу компоненты горени в зону сжигани подают одновременно в виде богатой и бедной смесей, полученных путем предварительного перемешивани компонентов горени внутри горелки, причем оптимальный коэффициент избытка воздуха богатой смеси составл ет 0,5-0,8, а бедной - 1,3-1,6, Кроме того, в потоки могут вводитьс инертные компоненты либо впрыскиватьс инертна жидкость. Предварительное смешение и одновременна подача двух типов смесей в зону горени способствует уменьшению времени пребывани The invention relates to methods for burning fuel and can be used to reduce the concentration of nitrogen oxides in combustion gases, in particular, in boiler units equipped with a burner. There are known methods for burning fuel in boiler units, in which part of the boiler burners work with lack of air. part with an excess of 1. However, such combustion methods have difficulty adjusting the ratio of air flow to the burners and complicate the operating conditions of the unit. In addition, the quality of combustion is deteriorated due to the gap between the main and additional torches of the burners, resulting in an increase in the content of soot and nitrogen oxides in the combustion products. Also known are methods of burning fuel, dried in a burner by simultaneously feeding two components to the combustion zone simultaneously, one of which is rich in air-fuel mixture 2. The disadvantages of such methods of burning fuel are when all the fuel burns in the first stage and then the products Combustion burns out in a stream of flowing air; the flame temperature is high, as well as a long residence time in the combustion zone, which leads to an increased content of nitrogen oxides in the combustion products. The purpose of the invention is to reduce the content of nitrogen oxides in the combustion products. This is achieved by the fact that the rich mixture is fed from a 0.5-0.8, and the second stream serves a lean air-fuel mixture from 1.3-1.6, where l is the coefficient of excess air. In addition, inert gases can be introduced into lean and rich mixtures, and an inert liquid, such as water, can also be injected. In the proposed method, the combustion components are fed to the combustion zone at the same time as rich and lean mixtures obtained by pre-mixing the combustion components inside the burner, the optimum excess air ratio of the rich mixture being 0.5-0.8, and the poor ratio 1.3. 1.6. In addition, inert components may be introduced into the streams or an inert liquid may be injected. Pre-mixing and simultaneous feeding of two types of mixtures to the combustion zone helps to reduce the residence time.
продуктов в зоне горени , а также снижает температуру факела, что способствует уменьшению содержани окислов азота в продуктах сгорани .products in the combustion zone, and also reduces the temperature of the flare, which helps to reduce the content of nitrogen oxides in the combustion products.
