FIELD: heat power engineering. ^ SUBSTANCE: method comprises preliminary water-oxygen cleaning and passivating of water-steam path of the power plant by means of a cleaning water-based agent in the mixture with oxygen at a high temperature of 350-450°C and high oxygen concentration of 1-2 g/kg. During operation, oxygen is supplied to the feeding water permanently, and at a concentration of ferrum compounds more than 10 mug/kg, oxygen is supplied periodically. The concentration of oxygen in feeding water ranges from 70 to 100 mug/kg. ^ EFFECT: enhanced safety. ^ 1 dwg, 2 ex |
