FIELD: power engineering.
SUBSTANCE: device for establishment of feed water mass flow controls flow rate of feed water, controlled value of which is mass flow of feed water, and specified value for which for mass flow of feed water is specified depending on specified value L assigned according to steam generator capacity, moreover, actual value ρE of feed water density at heater inlet is supplied to control of feed water flow as one of input values.
EFFECT: method for operation of direct-flow steam generator must allow for synchronous change of feed water mass flow through evaporating surface of heating and introduction of heat into evaporating surface of heating in any condition of technical plant operation without considerable technical expenses.
