METHOD OF OPERATION OF DUST SYSTEM AT PEAK BOILER MODES

摘要

This invention relates to the branch of preparation of fuel before feeding it to the units for burning. The method of operation of the dust system of boiler of heat power plant proposed is in fact that the under-mill separated from separator is not directed to the mill for repetitive milling, but collected and/or directly from separator it is supplied to the burner of the boiler where it is burned together with the main flow of coal dust. This invention promotes increase of productivity of the dust system in modes of peak loads of the boiler and its maneuverability.
