ANALOG COMPUTER SIMULATION OF ALLIS-CHALMERS/COMBUSTION ENGINEERING 20,000 SHP SELF-REGULATING STEAM GENERATOR
In a program designed to reduce costs of merchant ship construction and operation, a concept for a self regulating shipboard steam generating system was developed. An analog computer study was made to evaluate the characteristics of such a system under transient load conditions. Results of the study indicated satisfactoriness of the general principles of the system but indicated that some additional automation is required to obtain optimum transient response without excessive deviation of the controlled variables. It was also determined that the design of the boiler is such that a problem with excessive boiler water level excursions caused by inherent "shrink and swell" may exist. Alleviation of this condition can be expected to improve the self regulatory performance of the plant.
