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

Keywords: boiler, drying, dust preparation system, coal, studded zone, drying agent, burner, slag

Abstract

 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).
