Description
Изобретение.относится к энергетике и может быть использовано в различных топливосжигающих агрегатах, например, в печных установках.The invention relates to energy and can be used in various fuel combustion units, for example, in furnace installations.
Цель изобретения - снижение содержания окислов азота в продуктах сгорания путем их восстановления.The purpose of the invention is to reduce the content of nitrogen oxides in the combustion products by reducing them.
На чертеже представлена схема устройства для реализации предлагаемого способа.The drawing shows a diagram of the device for implementing the proposed method.
Устройство содержит сопло 1 для подачи в зону горения пылевоздушной смеси 5 и сопло 2 для подачи вторичного воздуха, Периферийная зона устройства состоит из ряда каналов 3, подключенных к источнику газообразного горючего. Выходные участки каналов 3 наклонены к оси потока. На чертеже показан фронт 4 воспламенения .The device contains a nozzle 1 for supplying the dust-air mixture 5 to the combustion zone and a nozzle 2 for supplying secondary air. The peripheral zone of the device consists of a series of channels 3 connected to a source of gaseous fuel. The output sections of the channels 3 are inclined to the flow axis. The drawing shows the front 4 of ignition.
Способ осуществляется следующим образом.The method is as follows.
Восходящая из сопла 1 топливовоздушная смесь смешивается с вторичным воздухом, выходящим из сопла 2, и воспламеняется. Газообразное горючее, выходярще из каналов 3 в виде острых струй, поступает за фронт 4 воспламенения в зону горения топливовоздушной смеси 5. При этом кон5 центрация кислорода в зоне горения уменьр'ается как посредством разбавле ния указанной смеси газообразным горючим, так и за счет взаимодействия высокореакционного горючегоThe air-fuel mixture ascending from the nozzle 1 is mixed with the secondary air leaving the nozzle 2 and ignited. The gaseous fuel coming out of the channels 3 in the form of sharp jets enters the ignition front 4 into the combustion zone of the air-fuel mixture 5. At the same time, the concentration of oxygen in the combustion zone decreases both by diluting the mixture with gaseous fuel and due to the interaction of highly reactive fuel
10 с килородом первичного и вторичного воздуха. Таким образом, количество кислорода, соединяющегося с азотом, который выделяется при горении пылевидного топлива, значительно сокра15 щается. Кроме того, вследствие высокой реакционной способности вещества вводимого за фронт воспламенения, указанное вещество восстанавливает часть образовавшихся окислов азота10 with a kilor of primary and secondary air. Thus, the amount of oxygen combining with nitrogen, which is released during the combustion of pulverized fuel, is significantly reduced. In addition, due to the high reactivity of the substance introduced over the front of ignition, this substance reduces part of the resulting nitrogen oxides.

2О+2Нг=2НгО + 22O + 2H g = 2H g O + 2
Все это приводит к снижению образования окислов азота по сравнениюAll this leads to a decrease in the formation of nitrogen oxides compared to
