摘要： PURPOSE: To prevent the seizure of a concn. boiler and to enhance working efficiency by enlarging the tolerant limit operation range of a concn. apparatus, in performing the operation of a membrane falling type concn. boiler, by controlling the inflow amount of the raw solution from an inlet by a relatively simple control method.
CONSTITUTION: In order to prevent the seizure in a membrane falling type concn. boiler 11 by controlling the flow amount of a raw solution at the inlet of said boiler 11, at first, the concn. D
0 of the concn. solution in the outlet pipe 13 of the concn. boiler 11 and the evaporation amount G
0 in a vapor pipe 15 are detected. The flow amount of the concn. solution per the unit peripheral length of the heat transfer surface in the concn. boiler 11 is calculated by operating said detected values by an operator 18 and subjected to the comparison operation with the solution amount of the conc. solution per a predetermined unit peripheral length required in preventing the seizure and output y
1 for determining the min. necessary inlet flow amount F
1 of the raw solution is operated on the basis of the operated values. On the other hand, output MV for determining the flow amount F
1 required in holding the concn. D
0 of the outlet conc. solution to a predetermined value is operated and the outputs y
1 MV are subjected to comparison operation in an operator 19 to output a value for increasing F
1 as y
2 while the set value of the inlet flow amount of the raw solution is controlled by y
2 and the inlet flow amount F
1 of the raw solution is controlled by the controlled set value.

0 and an evaporation amount G
0 are detected from the raw solution pipe 12, a concn. pipe 13 and a steam pipe 15 of a concn. boiler by detectors 1W4 and the deviation Z of the concn. D
0 and a set value is outputted by a concn. controller 17 and an operator 18 issues output (y) on the basis of the transmission function Y
0 operated from the aforementioned detected values and the deviation Z while output MV is operated in the controller 17 by P.I.D. operation based on P.I.D. constant and a raw solution flow amount set value and flow amount F
1 are compared by a flow amount controller 16 to operate a valve 5. In addition, process gain coefficient K
p is operated on the basis of the aforementioned detected values by the operator 18 and α is set to fixed coefficient to select the function Y
0 =α/K
p . By this method, the extremely stable automatic operation of the concn. control of the concn. solution is enabled.
