Description
При аварийном погаса ии пламени в топке ее стенки наход тс в раскаленном состо нии и излучают световой поток, который также пульсирует в результате поступлени в топку холодной смеси топлива и газа в виде завихренного потока. Но ввиду того, что фотодатчики 4 установлены один против другого на одной оптической оси и сфокусированы на темные п тна, вли ие светового потока раскаленных стенок топки на фотодатчики исключаетс . В свою очередь, фотодатчики, оказавшиес вне зоны действи светового потока, выдают сигнал в блок-схему управлени , котора подает команду на закрытие тонливного клапана (на чертеже не показан), а затем на повторный поджиг факела топки. При евоспламенении топлива после повторного поджига блок-схема управлени включает аварийную сигнализацию.In case of emergency extinguishing of the flame in the firebox, its walls are in a hot state and emit a luminous flux, which also pulsates as a result of the cold mixture of fuel and gas entering the furnace in the form of a vortex flow. But since the photosensors 4 are mounted one against the other on the same optical axis and are focused on dark spots, the influence of the light flux of the heated walls of the furnace on the photosensors is excluded. In turn, photosensors that are out of range of the luminous flux, give a signal to the control block diagram, which gives the command to close the thin valve (not shown in the drawing), and then to re-ignite the furnace flame. In the event of fuel ignition after re-ignition, the control flow chart includes an alarm.
