Control Algorithm Design for Large Boiler Dosing System
This article uses the mathematics method to study in view of boiler zero pollution discharge automatic dosing control and other aspects during the dosing control system model parameter is a variable instead of a constant. If the solution density changes, the object characteristic also along with the change, When the system load will change, can cause for the discharge of water changes, examines the PH value also can change along with it, will cause the controlled member model also correspondingly to change. Because the steam system heat supply pipeline has grown, a successful Canadian medicine circulation needs several minute perhaps several dozens minutes, overall system existence serious lag flaw. In view of the above, we used DDCSRD 3211B dosing system control system to eliminate hysteresis to ensure proper, efficient, energy-saving operation of steam boilers. Zero-effluent dosing system from steam to prevent pollution at the source, the boiler system to environmental decline in the discharge of sewage to zero or close to zero.[
