Abstract
Объектом изобретения является устройство измерения концентрации молекулы, такого как СО, NO, NO, в газовой атмосфере при температуре сверх 1200°С в камере, при этом упомянутая молекула имеет спектральную линию поглощения при длине волны от 4 до 8 мкм, при этом упомянутое устройство содержит излучатель (2) лазерного излучения с длиной волны, соответствующей длине волны спектральной линии поглощения, при этом упомянутый излучатель (2) излучает лазерное излучение через первое окно (4), затем через упомянутую атмосферу (7), при этом упомянутое окно (4) выполнено из твердого материала с коэффициентом пропускания, для толщины материала 1 мм, превышающим 50% при длине волны лазерного излучения, при этом лазерное излучение анализируют после прохождения через упомянутую атмосферу (7) при помощи анализатора (11), определяющего поглощение лазерного излучения молекулой в газовой атмосфере (7), при этом окно (4) расположено на или в стенке (6, 10) камеры, в случае необходимости, через вставку, чтобы препятствовать выходу горячей атмосферы из камеры. Устройством в соответствии с изобретением можно оборудовать стекловаренную печь для непрерывного измерения концентрации газообразных веществ в горячей атмосфере (7) во время нормальной работы печи (1). Это позволяет регулировать горелки печи во время работы.
