The Automatic Energy-Saving Control strategy for Coal-fired Boiler Heating System

摘要

This paper mainly introduces the energy-saving control strategy for coal-fired boiler heating system. The controlled objects of coal-fired boiler heating system includes the blowers of the boiler, the induced draft fan of the boiler, the chain for coal-carrying, the primary side water circulation and the secondary side water circulation. All the controlled objects are droved by electrical motors. By the optimal frequency conversion technical, more energy and coal can be saved.
