Description
мальной работе блока клапан на регенерации полностью открыт, поэтому сигнал 1 равен нулю, и сигнал 6, вл ющийс произведением сигнала 1 и 4, тоже равен нулю. Точно также соответственно равен нулю сигнал 10 на входе регул тора топлива, который Б этом случае работает по обычной схеме.When the unit is working, the valve on the regeneration is completely open, so signal 1 is equal to zero, and signal 6, which is the product of signal 1 and 4, is also zero. Similarly, the signal 10 at the input of the fuel regulator is equal to zero, which in this case works in the usual way.
При резком увеличении нагрузки регулирующий клапа« на линии отбора пара к ПВД начинает закрыватьс и тогда по витс сигпал 1 на выходе датчика 2 и сигналы 6 и 10. Сигнал 10 после блока 7 поступит на регул тор 8. Последний начнет увеличивать расход топлива в котел.With a sharp increase in the load, the regulating valve on the steam extraction line to the LDPE starts to close and then the sigpal 1 at the output of sensor 2 and the signals 6 and 10 will go.
Таким образом, выведение сигнала, характеризующего «произведение мощности на положение клапана, позвол ет по более правильному закону управл ть расходом топлиза . Топливо в топку будет поступать с учетомThus, the removal of a signal characterizing the "product of power at the valve position" allows, according to a more correct law, control of the fuel consumption. The fuel in the furnace will come with
предсто щего поступлени в котел «холодной воды. Благодар этому приемистость блока будет выше.The arrival of cold water in the boiler. Thanks to this acceleration of the block will be higher.

к регенеративному подогревателю с учетом сигналов, пропорциональных вырабатываемой мощности и положению клапана на линии отбора к подогревателю, отличающийс тем, что, с целью повыщени приемистости блока,to a regenerative preheater, taking into account signals proportional to the output power and the position of the valve on the extraction line to the preheater, characterized in that, in order to increase the capacity of the unit,
ополнительно измен ют расход топлива по сигналу, пропорциональному произведению сигналов по вырабатываемой мощности и но положению клапана на линии отбора к подогревателю .The fuel consumption is additionally changed by a signal that is proportional to the product of the signals according to the output power and the position of the valve on the extraction line to the preheater.
