Features of Deep Load Reduction of Mosenergo Drum-Type 130 kgf/cm2 Steam Pressure Boilers
At present, Mosenergo is carrying out computations and experiments to substantiate the possibility of reducing the minimum load for a group of natural-gas fired boilers (live steam pressure = 130 kgf/cm2) and ensuring continuous, without restrictions, operation of the main and auxiliary equipment. According to the operating documentation, the minimum load of Mosenergo boilers is 50 to 60%. To preliminarily assess the minimum permissible load, thermal and hydraulic analyses were carried out using specially developed mathematical models. To confirm that boilers can operate at a reduced load, to adjust the operating modes, and to determine the performance indicators, tests at various Mosenergo boilers were conducted. In the tests, the load of these boilers (TGME-464, TP-80, TP-80M, TP-87, TGM-84B, TGM-96) was reduced to 40 – 45% of the rating while maintaining the required reliability criteria, permissible environmental performance, and rated steam parameters.
