Programing on Combustion Control System for Boiler

The process control of combustion is of vital importance in the automatic control system for industrial boiler. Taking the coal-fired boiler as an example, there are three kinds of automatic control systems in the process of combustion, that is, "combustion-air "system, combustion system with heat quantity signal and system with oxygen quantity signal. By comparing with the performances of the three systems, it considers the control systm with heat quantity signal to be suitable to use. The system adopts computer control, modularization programing, and clock interrupt mode in data aquisition and control to realize fast monitoring, display, print results, automatic control boiler's operation and record paramenters, which achieves the goal of saving energy.
