ABSTRACT

The good working condition of the mills is very important for boilers, which use coal dust. The mills are very important for Power Plants because their work have a direct influence on the combustion process in the boiler furnace. On time controlling the mills condition and their correct repairing during a revision in accordance, technical standards enable unhindered work of the mills with a maximal load. Depending on the coal quality, a maximal load of the mills directly enables increasing of the heat in the boiler. In continue of the paper are shown the characteristic, parameters and capacity of the fans mills during tests: before overhaul (with current maintenance, with partial reparation with a lot of shortcomings) and after overhaul (with complete reparation). According to the received results, a comparative analyze was made for the effect of the mills' condition on the capacity of the boiler and of course of the Power Plant. In order to reach better characteristics of the mills, at the end of paper are mentioned measures for increasing mills‘ capacity for 20t/h with execution technically properly overhaul, with elimination on all gaps in the mills, with improving sealing on the whole coal line etc.
