Использование относится к теплоэнергетике и, более конкретно к способам защиты от коррозии и отложений пароводяных трактов энергетических блоков тепловых электростанций. Сущность изобретения: пароводяные тракты энергетических блоков подготавливают путем предварительного подогрева элементов энергетического блока до температуры не ниже 60oС и пассивации поверхностей подачей кислорода в рабочее тело, причем одновременно с подачей кислорода в рабочее тело подают поверхностно-активное вещество в виде аминосодержащих соединений. Подготовку тракта перед подачей кислорода производят очисткой их поверхностей путем подачи в рабочее тело поверхностно-активных веществ в виде аминосодержащих соединений, а в качестве аминосодержащего соединения используют флотамин. Подача кислорода осуществляется при нагрузке котла в диапазоне от растопочного до номинального значения до появления его концентраций в рабочем теле на выходе из трактов не ниже, чем 20 мг/кг.The use relates to a power system and, more specifically, to methods of protection against corrosion and deposits of steam-water paths of energy blocks of thermal power plants. The inventive steam-water paths of energy blocks are prepared by preheating the elements of the energy block to a temperature not lower than 60 o C and passivation of the surfaces by supplying oxygen to the working fluid, and simultaneously with the supply of oxygen to the working fluid serves surfactant in the form of amine-containing compounds. The tract is prepared before oxygen is supplied by cleaning their surfaces by supplying surfactants in the form of amine-containing compounds into the working fluid, and flotamine is used as an amine-containing compound. Oxygen is supplied at the boiler load in the range from the starting to the nominal value until its concentration in the working fluid at the outlet of the tract is not lower than 20 mg / kg.
