Fuzzy Adaptive Scheme of Boiler Combustion System and Its Relization

In burning coal boiler widely used in internal motivity,the common control scheme is to regard simply the ratio of air and coal as the simple function of burden(steam pressure) and be closed to the ratio connection.Therefore it cannot adapt well to the change of coal and burden.An on-line fuzzy adaptive control scheme is proposed to adapt the diverse coal and to improve the combustion efficiency.The method resolves the ubiquity problem of low thermal efficiency and serious waste and ensures the economical combustion in different working circs with different kind of coal.
