Does the opening degree of the smoke extractor inlet butterfly valve affect its speed? Please, masters, help to answer by giving some advice.
It should have an impact. . . It should be kept within a certain range; the opening degree of the butterfly valve also affects the pressure in the regenerator. Therefore, not only the speed of the smoke extractor needs to be taken into account, but also other factors
It does not affect the speed of the flue gas fan, but it is necessary to work well with the double-acting slide valve in order to properly control the pressure in the regenerator.
It won’t have any impact; the speed adjustment has nothing to do with the inlet butterfly valve.
The speed of the exhaust fan is determined by the speed of the motor; therefore, once the main motor is activated, its speed remains constant, regardless of whether the motor is in a charging or generating mode, and it has nothing to do with adjusting the high-temperature butterfly valve
The flue gas extractor – the main fan – and the generator/motor form a coaxial unit. Under normal operating conditions, the speed of this unit is controlled by the rated speed of the motor, whereas the rated speed of the motor is determined by the frequency of the power grid. The amount of energy recovered by the flue gas extractor can only be reflected in the change in the motor current; it cannot affect the speed of the flue gas extractor.
