AB - After the last revitalization of thermal power block of 100 MW in TPP  “Kostolac A”, made in the year 2004, during the operation of the plant,  pulverized coal deposition often occurred in horizontal sections of the  aero-mixture channels. Deposition phenomenon manifested itself in places  ahead of spherical compensators in the direction of flow of pulverized coal  to the burners, due to unfavorable configuration of these channels. Coal dust  deposited in the channels dried and spontaneously combusted, causing numerous  damage to channels and its isolation as well as the frequent stoppage of the  operation for necessary interventions. The paper presents the original  solution of reconstruction of aero-mixture channels which prevented  deposition of coal dust and its eventual ignition. In this way the  reliability of the mill plant is maximized and higher availability of boiler  and block as a whole is achieved.
