ни . с выхода измерительного блока 8 сигнал поступает на вход регулирующего прибора 10, с помощью которого осуществл етс , управление работой регулирующего органа 15. Положение подвижного щтока регулируюпдего органа контролируетс  указателем 16 положени , на который поступают одновременно сигналы от регулирующего ц рибора 10 и исполнительного механизма 17. При увеличении суммы сигналов уровн , расходов и температур увеличиваетс  величи на выходного сигнала регулирующего прибора 10, который открывает регулирующий орган 15, увеличива  подачу питате.дьной воды в барабан содорегенерационного котлоагрегата . Применение дополнительно измер емых сигналов по температуре сгорани  топлива в топочной камере котлоагрегата и температуре сгорани  на выходе из нее позвол ет снизить инерционность регулировани  за счет упреждающего учета и ликвидации возмущений , вызываемых нестабильностью полезного тепловыделени  в топочной камере и шлакованием поверхностей нагрева, топочной камеры. Формула изобретени  Способ автоматического регулировани  уровн  воды в барабане содорегенерационного котлоагрегата путем измерени  сигналов по уровню воды в барабане, расходам перегретого пара и питательной воды и нодачи этих сигналов на регул тор, воздействующий на регулирующий орган расхода питательнои воды, отличающийс  тем, что, с целью повыщени  точности регулировани , дополнительно измер ют сигналы по температуре сгорани  топлива в топочной камере котлоагрегата и температуре продуктов сгорани  на выходе из нее и подают их на регул тор одновременно с сигналами по уровню воды и расходам перегретого пара и питательной воды.

F 22 D 5/30, 1969.neither from the output of the measuring unit 8, the signal is fed to the input of the regulating device 10, with which the regulation body 15 is controlled. The position of the movable pin of the regulatory body is controlled by the position indicator 16, to which the signals from the regulator 10 and the actuator 17 are simultaneously received. With an increase in the sum of the signal level, flow rate and temperature increases the output signal of the regulating device 10, which opens the regulator 15, increasing the flow feed water into the drum of the recovery boiler; The use of additional measured signals based on the combustion temperature of the fuel in the boiler chamber of the boiler unit and the combustion temperature at the outlet from it allows reducing the inertia of control due to proactive accounting and elimination of disturbances caused by instability of the useful heat generation in the combustion chamber and slagging of heating surfaces, the combustion chamber. Claims The method of automatically adjusting the water level in the drum of a recovery boiler is measured by measuring the level of water in the drum, the consumption of superheated steam and feed water, and supplying these signals to a regulator acting on the regulator of the feed water flow, characterized in that control accuracy, in addition, the signals are measured by the temperature of combustion of fuel in the combustion chamber of the boiler unit and the temperature of the combustion products at the exit from it and feed them on the controller simultaneously with the signals on the water level and the flow of superheated steam and feed water.
