3.3 Solution Flow Rate Control
The reduction of the solution flow rate by the speed control of solution pump ensures an efficient
and stable operation in cooling operation at partial load.
Since the pressure of the high pressure generator reduces due to the reduction of the fuel
consumption in partial load, the solution level in the high pressure generator tends to rise up.
Detecting the solution level with the electrode, the speed of solution pump is controlled to keep the
correct level.
Level too high Solution pump stop
Level high Speed of solution pump
Ⅰ
decrease
Solution level in high Proper level Speed of solution pump
Ⅰ
unchanged
Pressure generator Level low Speed of solution pump
Ⅰ
Increase
Level too low Combustion stop
(Prevention of void combustion)
