Description
(54) СПОСОБ СЖИГАНИЯ TOFl/liiBA(54) METHOD OF BURNING TOFl / liiBA
Изобрэтение относитс к технике сжйганЕ топлива и мо сет быть использовано иреймущаственно в котельных агрегатах большой мощности, а также может примен тьс дл регулировани температуры первичного и вторичного пара газовым методом .The invention relates to a technique of fuel and power to be used and therefore in boiler units of high power, and can also be used to control the temperature of the primary and secondary steam by the gas method.
Извест 1Ы способы сжигани путем встречной подачи струй топлива н подачи снйзу газов рециркул ции i.Known combustion methods by the counter-feed of jets of fuel and the feed of a decrease in recirculation gases i.
Недостатками такого способа вл ютс низка надежность пароперегревател и высока концентраци окислов азота в продуктах сгорани , обусловленна неравномерностью скоростного и температурного полей в поперечном сечении топки пароге нератора.The disadvantages of this method are the low reliability of the superheater and the high concentration of nitrogen oxides in the combustion products, due to the uneven speed and temperature fields in the cross section of the steam generator.
Известен также способ сжигани топлива путем тангенциальной подачи топливо-«оздушной смесй аксиального отвода продуктов сгорани и одновременной пода чи газов рециркул ции в осевую часть закрученного факела 2 .There is also known a method of burning fuel by tangentially supplying an air / air mixture to the axial removal of combustion products and simultaneously feeding recirculation gases into the axial portion of a swirling flame 2.
Недостатками текого способа вл ютс низка гъ работы пг.роперегреватсл к BfcfcoKas когщектрах-.ин ок ;слоо аго« ТЕ b продуктах сгорани .The disadvantages of the current method are the low gj of the work of the superheater to BfcfcoKas co-spectra-in; ok; ago "TE" b combustion products.
Целью иаобре-тени вл етс повышекие нацежкости а сн11женйе вредных выбросов .The purpose of the shade is to increase national sensitivity and reduce harmful emissions.
Это достигаетс тем, ч-л газы рециркул дкк подают спутно направлению отгю да прод ктов сгорани . Кроме того, газы рецаркул цаи подают турбулизировакным потоком. При этом пол температур и скоростей выравниваютс .This is achieved by the fact that the h-l gases of the recirculated fuel cell supply are supplied in parallel to the direction of exhaust and combustion products. In addition, rezarkul tsai gases are supplied by a turbulization stream. In this case, the floors of the temperatures and velocities equalize.
lie фнГ;, 1 ;43ображен парогенератор, реализующий предлагаемый способ, гфодоль-ный разрезу на фиг. 2 - разрез Л-Л на Лиг. 1.lie fnG ;, 1; 43 depicts a steam generator that implements the proposed method, according to the section in FIG. 2 - LL slit on Lig. one.
Парогенератор содержит тога:у 1 с танге1щнальными горелками 2 и соплом 3 дл подачи газов рециркул ции.The steam generator contains togas: 1 with tangent burners 2 and a nozzle 3 for supplying recirculation gases.
К конвектиь;1эй шахте 4, в которой ус™ тановлеш парс-перегреватели 5, подк.тю чек трубогфовод 6 с вентнл торим 7 дл 1К1дачи газов рециркул5тцнк в сокпо 3.To the convection; 1st mine 4, in which the installation of the superheated steam superheaters 5, piped up the check of the pipe driver for 6 with ventilation 3 for 1 1 1 of the transfer of gases to recirculating gas in Sokpo 3.
