Abstract:
With the steady and rapid development of coal-f ired pow er plant s, the w eakness of usual w ater ash-handling system has become more obv ious fo r its w ater reso urce w ast ing , environment po llut ion and land occupat ion. It can be resolved by compressed air ash-handling method. In this paper , a negat ive-pressure air ash handling cont rol system is int ro duced, w hich is installed in thermopow er plant of Jingl in Pet ro-Chemical Works. By analy sing it s st ructure principle and pro grammable cont roller-based co nt rol st rategy , as w el l as three years pract ice, shown it is that this sy stem funct ion is advanced and o peratio n is r eliable. It may g uarantee the pow er product ion safe and hig h eff icient .
