【正文】 附錄2：外文翻譯PLC in steam boiler steam drum fluid position PID control system applied analysis 1 introductionThe industry steam boiler steam drum water monitor duty is the control causes it for the water current capacity with the transpiration rate maintenance dynamical equilibrium, maintains the steam drum water level in the craft permission scope, is guarantees the boiler safety in production movement the essential condition, also is one of boiler regular production movement major targets or quotas. If the water level excessively is high, affects the soft drink separation the effect, the use was mad the equipment breaks down。 But the water level excessively low can destroy the soft drink circulation, is serious when causes the explosion of a boiler, therefore the boiler steam drum water level must strictly control. In order to guarantee the boiler to produce stable, reliable and the economical movement, we designed use the performance to be advanced the boiler PID automatic control system which forever great automatic equipment and so on FBsPLC, frequency conversion velometer, puter application will pose. This control system through examination water vapor pressure, temperature, movement physical quantity and so on steam drum fluid position, in movement process entire automatic control, has guaranteed the industry boiler security stable highly effective movement.2 industries boilers related craft introductionThe steam boiler is the factories and mines important power equipment, its duty is the supplies qualified stable steam, satisfies the load the need. Therefore, boiler production process each main parameter all must strictly control. But holds the very great proportion using the afterheat gas as the heat change medium afterheat boiler in the nation, its energy conservation falls consumes the effect especially to be obvious. Some chemical plant sulfuric acid afterheat boiler is the furnace gas which es out using the ebullition stove (mainly is SO2) the hyperpyrexia, takes it as the heat change object, through afterheat boiler vice midproduction pressure steam for each production branch factory use, also has guaranteed the production need, also
