Abstract

FIELD: fuel combustion. SUBSTANCE: burner has gas supply nozzles 34,36,38 used to introduce air portion for combustion, and blade swirler 20 designed to rotate and mix gases in primary combustion region. Swirler 20 can be adjusted in axial direction to change distance between swirler 20 and first combustion region while blades of swirler 20 are adjustable in setting angle to optimize rotation and mixing of gases. Combustion air is supplied to air channel 16 to form various combustion regions so as to ensure complete combustion. Rate of air flow for combustion is controlled by means of flap 14 according to combustion characteristics. Additional reduction of toxic gas emissions is attained by recirculating furnace gases and mixing them with fuel for combustion prior to introduction in combustion chamber through reductor nozzles 34,36,38. Further reduction is attained by adding secondary compound, such as water or chemical agent, to circulating furnace gases so as to optimize combustion level thereby reducing emissions. EFFECT: reduced emission of nitrogen oxides that can be adjusted to obtain optimal combustion rates, temperatures, and oxygen content. 1 dwg

Предложена система 10 сгорания в виде горелки со сниженным выделением NOx, которою можно отргулировать для достижения оптимальных с скоростей горения, температур и уровней кислорода. Горелка включает в себя сопла 34, 36, 38 для подачи газов, через которые вводят порцию воздуха для сгорания, и лопастный завихритель 20 для вращения и смешения газов в зоне первичного сгорания. Завихритель 20 можно регулировать в осевом направлении, чтобы изменять расстояние между завихрителем 20 и первой зоной сгорания, тогда как лопатки завихрителя 20 можно регулировать по углу установки, чтобы оптимизировать вращение и смешение газов. Воздух для сгорания подают в воздушный канал 16, чтобы образовать различные зоны сгорания для обеспечения полного сгорания. Скорость потока воздуха для сгорания регулируют посредством заслонки 14 в соответствии с характеристиками горения. Дополнительных снижений ядовитых выделений достигают путем рециркуляции топочных газов и смешения их непосредственно с топливом для сгорания перед введением в камеру сгорания через эдукторные сопла 34, 36, 38. Дальнейших снижений достигают путем примешивания вторичного соединения, такого, как вода или химическое вещество, к рециркулированным топочным газам, чтобы оптимизировать уровни сгорания, снижая тем самым выделения.A combustion system 10 is proposed in the form of a burner with reduced NO x emission, which can be adjusted to achieve optimal combustion rates, temperatures, and oxygen levels. The burner includes nozzles 34, 36, 38 for supplying gases through which a portion of air for combustion is introduced, and a blade swirler 20 for rotating and mixing gases in the primary combustion zone. The swirl 20 can be axially adjusted to vary the distance between the swirl 20 and the first combustion zone, while the blades of the swirl 20 can be adjusted in the installation angle to optimize gas rotation and mixing. Combustion air is supplied to the air duct 16 to form various combustion zones to ensure complete combustion. The flow rate of combustion air is controlled by the shutter 14 in accordance with the combustion characteristics. Further reductions in toxic emissions are achieved by recirculating the flue gases and mixing them directly with the combustion fuel before being introduced into the combustion chamber through the eductor nozzles 34, 36, 38. Further reductions are achieved by mixing a secondary compound, such as water or a chemical, with the recycled flue gases to optimize combustion levels, thereby reducing emissions.
