On-Line Supervising System for Boiler Combustion of Power Station

To help operators of power station to monitor major operating parameters and accurately adjust air distribution, this system is developed independently on the base of fieldbus Technology and JBuilder software. And heat balance law is accepted as the principal for the measurement of pulverized coal´s concentration. This system could monitor and save operating parameters at all time, such as velocity and temperature of primary and secondary air, temperature of pulverized coal and pulverized coal-air, pulverized coal concentration. At the same time, it could realize past records inquiry, trend curve analysis, failures detection and alarm. So that this system could significantly improve boiler air distribution and combustion, and prevent pulverized coal-air pipe jam, then increase safety, stability and economy of boiler´s operation.
