MAIN CONCEPTUAL SOLUTIONS AND METHODS OF THEIR IMPLEMENTATION WHEN CHANGING THE 300 MW ENERGY UNITS FROM BURNING ANTHRACITE CULM TO BURNING COAL OF THE GAS GROUP
Various schemes have been developed for reconstructing the existing dust-system of the TPP-210A boiler of Unit № 4 of the Trypillia TPP with the discharge of the spent drying agent into the main burners (low-cost technologies) or into the cooling zone located above the pre-furnace and behind the boiler (medium-cost technologies). The advantages of medium-cost technologies over low-cost are shown, in particular, ensuring a high level of fire and explosion safety, slag-free operation and minimization of emergency injections due to redistribution of the ratio of drying agent entering the cooling zone and behind the boiler, a wide range of unit load changes from 150 to 285 MW. Two ways of switching the power unit to a load of 180 MW are shown: 1) by changing both bodies to a load of 60% of the nominal load without lighting with oil fuel (maneuvering mode); 2) by stopping one of the bodies and increasing the load of the second body to 165 MW (basic mode).
