Показано, что минимальная концентрация оксидов азота в дымовых газах образуется при сжигании топлива в горелках с разомкнутыми факелами и внешним смешением при сжигании низкокалорийных видов топлива. Подогрев воздуха горения в несколько раз увеличивает концентрацию оксидов азота в продуктах горения. Получена экстремальная зависимость концентрации оксидов азота в дымовых газах от величины коэффициента расхода воздуха, критическое значение которого, соответствующее максимальной величине концентрации, составляет 1,16 – 1,17.</p></abstract><trans-abstract xml:lang="en"><p>The concentration of nitrogen dioxide in the smoke gases from the combustion of fuel in burners with different ways of forming the fuel-air mixture was calculated with the use of empirical procedures. It was shown, that a minimum concentration of nitrogen oxides in smoke gases was at fuel burning in burners with open torches and external mixing incineration calorie fuels. The heating of the combustion air increased the concentration of nitrogen oxides in the combustion products in several times. The extreme dependence of the concentration of nitrogen oxides was obtained in the smoke from the coefficient of the air flow, the critical value of which corresponded to the maximum concentration – 1.16 – 1.17.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксиды азота</kwd><kwd>дымовые газы</kwd><kwd>горелка</kwd><kwd>способ смешения</kwd><kwd>подогрев воздуха горения</kwd><kwd>коэффициент расхода воздуха</kwd><kwd>экстремальная зависимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nitrogen oxides</kwd><kwd>smoke gases</kwd><kwd>burner</kwd><kwd>mixing method</kwd><kwd>heating of combustion air flow</kwd><kwd>rate of air</kwd><kwd>extreme dependence</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sigal I.Ya.
