FIELD: heat power engineering.
SUBSTANCE: method comprises cleaning and passivating the inner sides of the boiler pipes with a cleaning agent composed of a mixture of oxygen with feed water or vapor or water-vapor mixture. The concentration of oxygen is maintained within 10-15 g/kg. The cleaning is performed for 4.5-5.5 hours at a temperature of 90-950°C.
EFFECT: enhanced efficiency.
